(Summary) Craniopharyngioma (CP) is mainly classified into two pathological subtypes: adamantinomatous (ACP) and papillary (PCP). CTNNB1 (β-catenin) mutations are detected in ACPs, and the BRAF V600E mutation is detected in PCPs. However, genetic analysis is not always possible in general medical practice. In this study, we investigated whether immunohistochemistry could replace genetic analysis as an aid in subtype diagnosis. Here, 38 CP patients who had undergone their first tumor resection were included. Among the 38 cases, 22 were morphologically diagnosed as ACP, 10 cases were diagnosed as PCP, and six cases were diagnosed as undetermined CP that were morphologically difficult to classify as either ACP or PCP. Results of immunohistochemistry and genetic analysis and clinical features were compared. Based on the immunohistochemistry, 26 (22 ACPs and four undetermined CPs) showed nuclear β-catenin expression, 11 (nine PCPs and two undetermined CPs) exhibited positive BRAF V600E immunostaining, and one PCP showed membranous β-catenin expression and negative BRAF V600E immunostaining. Among the 26 nuclear β-catenin expression cases, 11 had CTNNB1 mutations; however, 15 cases had mutations of neither CTNNB1 nor BRAF V600E. All 11 BRAF V600E immunopositive cases had BRAF V600E mutations. When comparing clinical features, pediatric patients and those with tumor calcification and less solid components on MRI more commonly had nuclear β-catenin expression tumors than BRAF V600E immunopositive tumors, reflecting the differences in clinical features between ACP and PCP. Accordingly, immunohistochemistry can replace genetic analysis as an aid to determine the subtype diagnosis of CP in general medical practice.

(Summary) Germline mutations in the aryl hydrocarbon receptor-interacting protein (AIP) gene are responsible for a subset of familial isolated pituitary adenoma (FIPA) cases and sporadic pituitary neuroendocrine tumors (PitNETs). To compare prospectively diagnosed AIP mutation-positive (AIPmut) PitNET patients with clinically presenting patients and to compare the clinical characteristics of AIPmut and AIPneg PitNET patients. 12-year prospective, observational study. We studied probands and family members of FIPA kindreds and sporadic patients with disease onset ≤18 years or macroadenomas with onset ≤30 years (n = 1477). This was a collaborative study conducted at referral centers for pituitary diseases. AIP testing and clinical screening for pituitary disease. Comparison of characteristics of prospectively diagnosed (n = 22) vs clinically presenting AIPmut PitNET patients (n = 145), and AIPmut (n = 167) vs AIPneg PitNET patients (n = 1310). Prospectively diagnosed AIPmut PitNET patients had smaller lesions with less suprasellar extension or cavernous sinus invasion and required fewer treatments with fewer operations and no radiotherapy compared with clinically presenting cases; there were fewer cases with active disease and hypopituitarism at last follow-up. When comparing AIPmut and AIPneg cases, AIPmut patients were more often males, younger, more often had GH excess, pituitary apoplexy, suprasellar extension, and more patients required multimodal therapy, including radiotherapy. AIPmut patients (n = 136) with GH excess were taller than AIPneg counterparts (n = 650). Prospectively diagnosed AIPmut patients show better outcomes than clinically presenting cases, demonstrating the benefits of genetic and clinical screening. AIP-related pituitary disease has a wide spectrum ranging from aggressively growing lesions to stable or indolent disease course.

(Summary) BACKGROUND Alteration of DNA methylation of tumor suppressor genes (TSGs) is one of the most consistent epigenetic changes in human cancers. DNMTs play several important roles in DNA methylation and development of cancers. Regarding DNMTs protein expressions, little is known about the clinical significance and correlation with promoter methylation status of TSGs in human pituitary adenomas. MATERIAL AND METHODS We analyzed the protein expression of 3 DNMTs using immunohistochemistry and assessed DNA hypermethylation of RASSF1A, CDH13, CDH1, and CDKN2A (p16) in 63 pituitary adenomas. We examined associations between DNMTs expression and clinicopathological features or promoter methylation status of TSGs. RESULTS Overexpression of DNMTs was detected in pituitary adenomas. Frequencies of DNMT1 overexpression were significantly higher in macroadenomas, invasive tumors, and grade III and IV tumors. DNMT3A was frequently detected in invasive tumors and grade IV tumors. In addition, DNMT1 and DNMT3A were frequently detected in high-methylation tumors. Furthermore, in multivariate logistic regression, the significant association between DNMT1 or DNMT3A and high-methylation status persisted after adjusting for clinicopathological features. CONCLUSIONS Our findings suggested that tumor overexpression of DNMT1 and DNMT3A is associated with tumor aggressive behavior and high-methylation status in pituitary adenomas. Our data support a possible role of DNMT1 and DNMT3A in TSG promoter methylation leading to pituitary adenoma invasion and suggest that inhibition of DNMTs has the potential to become a new therapeutic approach for invasive pituitary adenoma.

(Summary) Predictive tools to identify patients at risk for gene mutations related to pituitary adenomas are very helpful in clinical practice. We therefore aimed to develop and validate a reliable risk category system for aryl hydrocarbon receptor-interacting protein () mutations in patients with pituitary adenomas. An international cohort of 2227 subjects were consecutively recruited between 2007 and 2016, including patients with pituitary adenomas (familial and sporadic) and their relatives. All probands (n=1429) were screened for mutations, and those diagnosed with a pituitary adenoma prospectively, as part of their clinical screening (n=24), were excluded from the analysis. Univariate analysis was performed comparing patients with and without mutations. Based on a multivariate logistic regression model, six potential factors were identified for the development of a risk category system, classifying the individual risk into low-risk, moderate-risk and high-risk categories. An internal cross-validation test was used to validate the system. 1405 patients had a pituitary tumour, of which 43% had a positive family history, 55.5% had somatotrophinomas and 81.5% presented with macroadenoma. Overall, 134 patients had an mutation (9.5%). We identified four independent predictors for the presence of an mutation: age of onset providing an odds ratio (OR) of 14.34 for age 0-18 years, family history (OR 10.85), growth hormone excess (OR 9.74) and large tumour size (OR 4.49). In our cohort, 71% of patients were identified as low risk (<5% risk of mutation), 9.2% as moderate risk and 20% as high risk (≥20% risk). Excellent discrimination (c-statistic=0.87) and internal validation were achieved. We propose a user-friendly risk categorisation system that can reliably group patients into high-risk, moderate-risk and low-risk groups for the presence of mutations, thus providing guidance in identifying patients at high risk of carrying an mutation. This risk score is based on a cohort with high prevalence of mutations and should be applied cautiously in other populations.

(Summary) Growth hormone (GH)-producing pituitary adenomas (PAs) in childhood or young adulthood are rare, and the details surrounding these tumors remain enigmatic. We present the clinical, pathological and genetic features of this disease. We identified 25 patients aged 20 years or younger with GH-producing PAs who underwent surgery between 2003 and 2016 at Toranomon Hospital in Tokyo. We retrospectively reviewed the clinical data, treatment outcomes and pathological features of these patients to shed light on childhood acromegaly. The cohort comprised 14 male and 11 female patients whose average age at the time of surgery was 17.3 years. Germline AIP mutations were present in 5 of 13 patients examined, and Carney complex was identified in 2 of 25 patients. The mean maximum tumor diameter was 26.7 mm, and total resection assessed during surgery was achieved in 17 patients. Based on their respective pathological findings, patients were divided into the following 4 groups: sparsely granulated adenomas (5), densely granulated (DG) adenomas (6), plurihormonal adenomas (9), and silent subtype 3 (SS3) adenomas (5). During the mean follow-up period of 50.3 months, complete endocrinological remission was achieved in 14 of 25 patients (56%) by surgery alone and in 19 patients (76%) after postoperative adjuvant therapy. GH-producing PAs in young patients are intriguing and difficult to treat due to their distinct tumor characteristics, including a lower incidence of the DG subtype and a higher incidence of SS3 adenomas and genetic abnormalities. Therefore, multi-modal therapies are essential to achieve optimal clinical outcomes.

(Summary) In adipose tissue, D-dopachrome tautomerase (DDT), a cytokine with structural similarity to macrophage migration inhibitory factor, is mainly expressed in adipocytes rather than preadipocytes and acts as an anti-obesity adipokine in an autocrine manner. However, its transcriptional regulation is largely unknown. In order to explore molecules affecting DDT transcription, a chemical library screening using HEK293 cells stably expressing a DDT promoter-reporter construct was performed. Several derivatives of 5-aminoimidazole-4-carboxamide-1--d-ribofuranoside (AICAR), an AMP-activated protein kinase (AMPK) activator, were identified as transcriptional activators of the DDT gene. Furthermore, DDT mRNA levels were reduced in SGBS adipocytes treated with compound C, an AMPK inhibitor, suggesting involvement of AMPK in DDT transcription. Overexpression of the FOXO1 constitutive active form reduced transcriptional activity of the DDT gene in SGBS cells, but increased it in HEK293 cells. Cell-type specific effects were also observed in the DDT gene expression of cells treated with AS1842856, a FOXO1 inhibitor. Finally, involvement of the mammalian target of rapamycin (mTOR) signaling in DDT transcription in SGBS adipocytes was investigated. Rapamycin, an inhibitor of mTOR, increased DDT mRNA levels and attenuated the inhibitory effects of compound C on DDT mRNA levels in SGBS adipocytes. In conclusion, DDT transcription may be regulated in a cell-dependent manner, and were enhanced by AMPK activation in SGBS adipocytes through inhibiting the mTOR signaling.

Here, we established a novel Chinese hamster ovary (CHO)-K1-derived cell line, CHO-K1-G34M, which carries a nonsense mutation (termed the Q525X mutation) in the GADD34 gene. The Q525X mutant protein lacks the C-terminal 66 amino acids required for GADD34 to bind to and activate protein phosphatase 1 (PP1). We investigated the effects of GADD34 with or without the Q525X mutation on the phosphorylation status of PP1 target proteins, including the subunit of eukaryotic initiation factor 2 (eIF2) and glycogen synthase kinase 3 (GSK3). CHO-K1-G34M cells had higher levels of eIF2 phosphorylation compared to the control CHO-K1-normal cells both in the presence and absence of endoplasmic reticulum stress. Overexpression of the wild-type GADD34 protein in CHO-K1-normal cells largely reduced eIF2 phosphorylation, while overexpression of the Q525X mutant did not produce similar reductions. Meanwhile, neither wild type nor Q525X mutation of GADD34 affected the GSK3 phosphorylation status. GADD34 also did not affect the canonical Wnt signaling pathway downstream of GSK3. Cell proliferation rates were higher, while expression levels of the cyclin-dependent kinase inhibitor p21 were lower in CHO-K1-G34M cells compared to the CHO-K1-normal cells. The GADD34 Q525X mutant had a reduced ability to inhibit cell proliferation and enhance p21 expression of the CHO-K1-normal cells compared to the wild-type GADD34 protein. These results suggest that the GADD34 protein C-terminal plays important roles in regulating not only eIF2 dephosphorylation but also cell proliferation in CHO-K1 cells.

(Summary) Mechanical stimuli regulate fundamental cell processes such as proliferation, differentiation, and morphogenesis. We attempted to identify microRNA (miRNA) whose expression is changed during compressive treatment in MC3T3-E1, a pre-osteoblastic cell line. Microarray analysis followed by reverse transcription-quantitative polymerase chain reaction revealed that compressive force at 294 Pa for 24 h in MC3T3-E1 cells increased levels of miR-494-3p, miR-146a-5p, miR-210-3p, and miR-1247-3p. Among these miRNAs, miR-494-3p was found to inhibit cell proliferation in MC3T3-E1 cells. Furthermore, cells subjected to compressive force showed slower cell growth compared with control cells. Levels of mRNA for fibroblast growth factor receptor 2 (FGFR2) and Rho-associated coiled-coil kinase 1 (ROCK1), which were predicted to be targets of miR-494-3p, were decreased by compressive force or overexpression of miR-494-3p mimics in MC3T3-E1 cells. Furthermore, binding sites of miR-494-3p within 3'-untranslated regions of Fgfr2 and Rock1 were determined using luciferase reporter assay. In conclusion, compressive force affected expressions of several miRNAs including miR-494-3p in MC3T3-E1 cells. Compressive force might inhibit cell proliferation in osteoblasts by up-regulating miR-494-3p followed by FGFR2 and ROCK1 gene repressions.

(Summary) The objective was to assess involvement of loss of the PRKAR1A gene encoding a type 1α regulatory subunit of cAMP-dependent protein kinase A located on 17q24 in a Carney complex (CNC)-related pituitary adenoma. We investigated aberrations of the PRKAR1A gene in a CNC patient with a GH-producing pituitary adenoma, whose family has three other members with probable CNC. A gene mutation was identified by a standard DNA sequencing method based on PCR. DNA copy number was measured to evaluate allelic loss on 17q24 by quantitative PCR. The breakpoints of deletion were determined by cloning a rearranged region in the deleted allele. A PRKAR1A mutation of c.751_758del8 (p.S251LfsX16) was found in genomic DNA obtained from a pituitary adenoma, but not leukocytes from the patient. Reduced DNA copy number at loci including the PRKAR1A gene on 17q24 was detected in both the tumor and leukocytes, suggesting a deletion at the loci at the germline level. The deletion size was determined to be ∼ 0.5 Mb and this large deletion was also found in two other family members. This is the first case showing a CNC-related pituitary adenoma with the combination of somatic mutation and a large inherited deletion of the PRKAR1A gene. Biallelic inactivation of PRKAR1A appears to be necessary for the development of CNC-related pituitary adenoma.

(Summary) MicroRNAs (miRNAs) are a class of recently identified noncoding RNAs that regulate gene expression at posttranscriptional level. Due to the large number of genes regulated by miRNAs, miRNAs play important roles in many cellular processes. Emerging evidence indicates that miRNAs are dysregulated in pituitary adenomas, a class of intracranial neoplasms which account for 10-15% of diagnosed brain tumors. Deregulated miRNAs and their targets contribute to pituitary adenomas progression and are associated with cell cycle control, apoptosis, invasion, and pharmacological treatment of pituitary adenomas. To provide an overview of miRNAs dysregulation and functions of these miRNAs in pituitary adenoma progression, we summarize the deregulated miRNAs and their targets to shed more light on their potential as therapeutic targets and novel biomarkers.

(Summary) Globalization of the professions has become a necessity among schools and universities across the world. It has affected the medical and dental professions in terms of curriculum design and student and patient needs. In Japan, where medicine and dentistry are taught mainly in the Japanese language, profession-based courses in English, known as Medical English and Dental English, have been integrated into the existing curriculum among its 83 medical and 29 dental schools. Unfortunately, there is neither a core curriculum nor a model syllabus for these courses. This report is based on a survey, two discussion forums, a workshop, and finally, the drafting of a proposed core curriculum for dental English approved by consensus of the participants from each university. The core curriculum covers the theoretical aspects, including dental English terms and oral pathologies; and practical aspects, including blended learning and dentist-patient communication. It is divided into modules and is recommended to be offered for at least two semesters. The core curriculum is expected to guide curriculum developers in schools where dental English courses are yet to be offered or are still in their early development. It may also serve as a model curriculum to medical and dental schools in countries in Asia, Europe, Africa, and Central and South America, where English is not the medium of instruction.

(Summary) Although the cause of familial isolated pituitary adenoma (FIPA) remains unknown in many cases, germline mutations in the aryl hydrocarbon receptor-interacting protein (AIP) gene were identified in approximately 20 % of families with FIPA. We investigated the AIP gene mutation by a standard sequencing method in 12 members of a Japanese two-generation FIPA family, which includes 3 patients with early-onset acromegaly. Multiplex ligation-dependent probe amplification analysis in a tumor sample was attempted to examine the loss of heterozygosity (LOH) in the locus. The effect of the detected mutation on cell proliferation was investigated. A germline mutation of c.943C > T (p.Q315X) generating an AIP protein with the C-terminal end deleted was found in the FIPA family. Biallelic inactivation of AIP by a combination of the germline mutation and LOH at 11q13 was confirmed in the tumor. The nonsense mutation disrupted the ability to inhibit cell proliferation. We conclude that p.Q315X mutation in the AIP gene is a pathogenic variant and the C-terminal region of AIP plays an important role in the predisposition to pituitary adenomas.

(Summary) Cushing disease is a potentially lethal condition resulting from hormone excess, usually due to a small pituitary tumor that fails to respond to negative feedback inhibition. A minority of patients develop larger, more aggressive tumors of the same lineage but with modest hormone excess. Here we show that a common polymorphism in the fibroblast growth factor receptor 4 (FGFR4) transmembrane domain yields receptor isoforms with distinct properties that mediate these biological differences. Forced expression of the major FGFR4-G388 variant allele supports pY-signal transducer and activator of transcription (STAT3) responses. In contrast, expression of the minor FGFR4-R388 allele enhances STAT3 serine phosphorylation, driving cellular growth. In addition, FGFR4-R388 enhances glucocorticoid receptor phosphorylation and nuclear translocation. Consistent with these findings, glucocorticoid administration resulted in enhanced hormone negative feedback in mice with knock-in of the FGFR4 variant allele. Moreover, clinical data from patients with pituitary tumors revealed that those homozygous for the R388 allele have a higher frequency of silent corticotroph macroadenomas than FGFR4-G388 carriers, who were more likely to have small but hormonally active microadenomas. These findings demonstrate that the FGFR4 transmembrane polymorphic variants can modulate cellular growth and sensitivity to glucocorticoid hormone negative feedback through distinct STAT3 modifications of relevance to the human forms of Cushing disease.

(Summary) 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is a potent toxin that alters normal brain development, producing cognitive disability and motor dysfunction. Previous studies in rats have proved that female rats are more sensitive to TCDD lethality than male ones. Recent studies have shown that TCDD induces cell cycle arrest and apoptosis, but the regulatory proteins involved in these processes have yet to be elucidated. In this study, we constructed an acute TCDD injury female rat model, and investigated the effects of TCDD on apoptosis and expression of cell cycle regulators, forkhead box class O 3a (FoxO3a) and p27(kip1), in the central nervous system (CNS). Increased levels of active caspase-3 were observed in the cerebral cortex of female rats treated with TCDD, suggesting that TCDD-induced apoptosis occurs in the CNS. The terminal deoxynucleotidyl transferase-mediated biotinylated-dUTP nick-end labeling assay showed that apoptosis primarily occurred in neurons. Furthermore, Western blot analysis, reverse transcription-polymerase chain reaction, and immunohistochemistry showed a significant up-regulation of FoxO3a and p27(kip1) in the cerebral cortex. Immunofluorescent labeling indicated that FoxO3a and p27(kip1) were predominantly localized in apoptotic neurons, but not in astrocytes. In vitro experiments using PC12, a rat neuron-like pheochromocytoma cell line, also revealed that TCDD induced apoptosis and an increase in FoxO3a and p27(kip1) expression. Furthermore, knockdown of FoxO3a expression inhibited p27(kip1) transcription and TCDD-induced apoptosis. Based on our data, induction of FoxO3a may play an important role in TCDD-induced neurotoxicity.

(Summary) 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is an environmental toxin that induces apoptosis of neurons and a pro-inflammatory response in microglial cells. First, we found that TCDD induced proliferation of HAPI microglial cells in a dose- and time-dependent manner. Flow cytometry analysis showed that this proliferation by TCDD was due to mainly enhancing the G1 to S phase transition. Next, it was found that TCDD treatment led to up-regulation of cyclin D1, which induces cell cycle progression from G1 to S phase, in a time-dependent manner. As for molecular mechanism, we revealed that TCDD was capable of inducing Akt phosphorylation and activation, resulting in phosphorylation and inactivation of glycogen synthase kinase-3 (GSK-3). Inactivated GSK-3 attenuated proteasomal degradation of cyclin D1 by reducing Thr(286)-phosphorylated cyclin D1 levels. Moreover, inactivated GSK-3 increased cyclin D1 gene transcription by increasing its transcription factor -catenin in the nucleus. Further, blockage of phosphoinositide 3-kinase/Akt kinase with their specific inhibitors, LY294002 and Akt 1/2 kinase inhibitor, significantly reduced TCDD-enhanced proliferation of HAPI microglial cells. In conclusion, TCDD stimulates proliferation of HAPI microglial cells by affecting the Akt/GSK-3/cyclin D1 signaling pathway.

(Summary) 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) has been known to induce inflammatory signaling in a number of cell types and tissues. However, the adverse effects of TCDD on the central nervous system (CNS) have not been entirely elucidated. In this study, using reverse transcriptase PCR (RT-PCR) and ELISA, we showed that TCDD up-regulated the expression and secretion of tumor necrosis factor-alpha (TNF-α) in a time-dependent manner in cultured HAPI microglial cells. TCDD also caused a fast (within 30min as judged by the increase in its mRNA level) activation of cytosolic phospholipase A2 (cPLA2). This initial action was accompanied by up-regulation of cyclooxygenase-2 (COX-2), an important inflammation marker within 1h after TCDD treatment. These pro-inflammatory responses were inhibited by two types of Ca(2+) blockers, bis-(o-aminophenoxy) ethane-N,N,N',N'-tetra-acetic acid acetoxymethyl ester (BAPTA-AM) and nifedipine, thus, indicating that the effects are triggered by initial increase in the intracellular concentration of free Ca(2+) ([Ca(2+)]i). Further, TCDD exposure could induce phosphorylation- and ubiquitination-dependent degradation of I Bα, and the translocation of NF-κB p65 from the cytosol to the nucleus in this microglial cell line. Thus, the NF-κB signaling pathway can be activated after TCDD treatment. However, Ca(2+) blockers also obviously attenuated NF-κB activation and transnuclear transport induced by TCDD. In concert with these results, we highlighted that the secretion of pro-inflammatory cytokine and NF-κB activation induced by TCDD can be mediated by elevation of [Ca(2+)]i in HAPI microglial cells.

(Summary) We previously identified d-dopachrome tautomerase (DDT) as a novel adipokine whose mRNA levels in adipocytes are negatively correlated with obesity-related clinical parameters, and which acts on adipocytes to regulate lipid metabolism. Here we investigated functions of DDT on preadipocytes. Recombinant DDT (rDDT) enhanced both the expression and secretion of interleukin-6 (IL-6) in SGBS cells, a human preadipocyte cell line. Treatment with rDDT increased levels of phosphorylated ERK1/2, but not p38, in SGBS cells, and rDDT-induced IL-6 mRNA expression was attenuated by pretreatment with an ERK inhibitor, U0126. Knockdown of CD74, but not CD44, inhibited rDDT-induced IL-6 mRNA expression in SGBS cells. These results suggested that the rDDT-induced IL-6 expression in preadipocytes occurred through the CD74-ERK pathway. Furthermore, in SGBS cells subjected to adipogenic induction, rDDT decreased the amount of triacylglycerol, number of cells with oil droplets, and levels of mRNA encoding adipocyte marker proteins. Increased expression of CCAAT/enhancer binding protein families and peroxisome proliferator-activated receptor 2 during adipogenesis was inhibited in the cells treated with rDDT. These results suggested DDT to inhibit adipogenesis by suppressing the expression of genes encoding adipogenic regulators in preadipocytes.

(Summary) Adipose tissue is a critical exchange center for complex energy transactions involving triacylglycerol storage and release. It also has an active endocrine role, releasing various adipose-derived cytokines (adipokines) that participate in complex pathways to maintain metabolic and vascular health. Here, we found D-dopachrome tautomerase (DDT) as an adipokine secreted from human adipocytes by a proteomic approach. DDT mRNA levels in human adipocytes were negatively correlated with obesity-related clinical parameters such as BMI, and visceral and subcutaneous fat areas. Experiments using SGBS cells, a human preadipocyte cell line, revealed that DDT mRNA levels were increased in an adipocyte differentiation-dependent manner and DDT was secreted from adipocytes. In DDT knockdown adipocytes differentiated from SGBS cells that were infected with the adenovirus expressing shRNA against the DDT gene, mRNA levels of genes involved in both lipolysis and lipogenesis were slightly but significantly increased. Furthermore, we investigated AMP-activated protein kinase (AMPK) signaling, which phosphorylates and inactivates enzymes involved in lipid metabolism, including hormone-sensitive lipase (HSL) and acetyl-CoA carboxylase (ACC), in DDT knockdown adipocytes. The AMPK phosphorylation of HSL Ser-565 and ACC Ser-79 was inhibited in DDT knockdown cells and recovered in the cells treated with recombinant DDT (rDDT), suggesting that down-regulated DDT in adipocytes brings about a state of active lipid metabolism. Furthermore, administration of rDDT in db/db mice improved glucose intolerance and decreased serum free fatty acids levels. In the adipose tissue from rDDT-treated db/db mice, not only increased levels of HSL phosphorylated by AMPK, but also decreased levels of HSL phosphorylated by protein kinase A (PKA), which phosphorylates HSL to promote its activity, were observed. These results suggested that DDT acts on adipocytes to regulate lipid metabolism through AMPK and/or PKA pathway(s) and improves glucose intolerance caused by obesity.

(Summary) Insulin-responsive aminopeptidase (IRAP) and GLUT4 are two major cargo proteins of GLUT4 storage vesicles (GSVs) that are translocated from a postendosomal storage compartment to the plasma membrane (PM) in response to insulin. The cytoplasmic region of IRAP is reportedly involved in retention of GSVs. In this study, vimentin was identified using the cytoplasmic domain of IRAP as bait. The validity of this interaction was confirmed by pull-down assays and immunoprecipitation in 3T3-L1 adipocytes. In addition, it was shown that GLUT4 translocation to the PM by insulin was decreased in vimentin-depleted adipocytes, presumably due to dispersing GSVs away from the cytoskeleton. These findings suggest that the IRAP binding protein, vimentin, plays an important role in retention of GSVs.

(Summary) The alteration of DNA methylation is one of the most common epigenetic changes in human cancers. Three genes, namely, DNA methyltransferase 1, 3a, and 3b, which code for DNA methyltransferases that affect promoter methylation status, are thought to play an important role in the development of cancers and may be good anticancer therapy targets. The methylation of tumor suppressor genes has been reported in gastroenteropancreatic neuroendocrine tumors; however, there have been no studies about DNA methyltransferase protein expression and its clinical significance in gastroenteropancreatic neuroendocrine tumors. In this study, the expression of DNA methyltransferase 1, 3a, and 3b was studied in 63 gastroenteropancreatic neuroendocrine tumors by immunohistochemistry. The expression of DNA methyltransferase 1, 3a, and 3b was frequently detected in gastroenteropancreatic neuroendocrine tumors (87%, 81%, and 75%, respectively). The DNA methyltransferase 3a expression level was significantly higher in poorly differentiated neuroendocrine carcinomas than in well-differentiated neuroendocrine tumors or well-differentiated neuroendocrine carcinomas (P < .01 and P < .05, respectively). The expression of DNA methyltransferase 1, 3a, and 3b showed significantly higher levels in stage IV tumors than in stage I or II tumors. In addition, the expression levels of DNA methyltransferase 1, 3a, and 3b were positively correlated with the MIB-1 labeling index in gastroenteropancreatic neuroendocrine tumors (R = 0.293, P = .019; R = 0.457, P = .001; and R = 0.249, P = .049; respectively). In addition, the expression levels and positive immunostaining frequencies of DNA methyltransferase 3a and 3b were significantly lower in midgut neuroendocrine tumors than in foregut or hindgut neuroendocrine tumors. Our findings suggest that the overexpression of DNA methyltransferase 1, 3a, and 3b is related to tumorigenesis and the progression of gastroenteropancreatic neuroendocrine tumors.

Lu Elaine Wang, Zhi-Rong Qian, Mustafizur Md Rahman, Katsuhiko Yoshimoto, Shozo Yamada, Eiji Kudo and Toshiaki Sano : Increased expression of HMGA1 correlates with tumour invasiveness and proliferation in human pituitary adenomas., Histopathology, Vol.56, No.4, 501-509, 2010. (Summary) AIMS: High-mobility group A1 (HMGA1) is highly expressed in various benign and malignant tumours. The development of pituitary adenoma in Hmga1 transgenic mice has been reported. However, no studies have investigated HMGA1 expression and its clinical significance in human pituitary adenomas. METHODS AND RESULTS: Immunohistochemical expression of HMGA1 was analysed with respect to various clinicopathological factors in 95 pituitary adenomas. Nuclear expression of HMGA1 was observed in 62% of pituitary adenomas, whereas normal adenohypophysial tissues were negative. Although HMGA1 expression was frequently detected in clinically non-functioning adenomas - 90% of silent adrenocorticotropic hormone (ACTH), 76.2% of follicle-stimulating hormone/luteinizing hormone and 100% of null cell adenomas - it was also detected in 48.1% of growth hormone (GH), 60% of mixed GH/prolactin (PRL), 62.5% of PRL, 66.6% of thyroid-stimulating hormone and 37.5% of ACTH adenomas. HMGA1 expression was significantly higher in invasive adenomas or macroadenomas than in non-invasive adenomas or microadenomas (invasive versus non-invasive, P < 0.05; macroadenoma versus microadenoma, P < 0.05). In addition, HMGA1 showed the highest level in grade IV, more aggressive pituitary adenomas, than in grades I, II and III (IV versus I, P = 0.01; IV versus II, P = 0.01; IV versus III, P = 0.07). Furthermore, a significant correlation between HMGA1 expression and MIB-1 labelling index was observed (R = 0.368, P < 0.0002). CONCLUSIONS: These findings suggest that HMGA1 up-regulation has an important oncogenic role in pituitary tumorigenesis, as well as being a novel molecular marker of tumour proliferation and invasiveness.

(Summary) BACKGROUND: The Toll-like receptor (TLR) 4 signalling pathway has been shown to have oncogenic effects in vitro and in vivo. To demonstrate the role of TLR4 signalling in colon tumourigenesis, we examined the expression of TLR4 and myeloid differentiation factor 88 (MyD88) in colorectal cancer (CRC). METHODS: The expression of TLR4 and MyD88 in 108 CRC samples, 15 adenomas, and 15 normal mucosae was evaluated by immunohistochemistry, and the correlations between their immunoscores and clinicopathological variables, including disease-free survival (DFS) and overall survival (OS), were analysed. RESULTS: Compared with normal mucosae and adenomas, 20% cancers displayed high expression of TLR4, and 23% cancers showed high expression of MyD88. The high expression of TLR4 and MyD88 was significantly correlated with liver metastasis (P=0.0001, P=0.0054). In univariate analysis, the high expression of TLR4 was significantly associated with shorter OS (hazard ratio (HR): 2.17; 95% confidence interval (95% CI): 1.15-4.07; P=0.015). The high expression of MyD88 expression was significantly associated with poor DFS and OS (HR: 2.33; 95% CI: 1.31-4.13; P=0.0038 and HR: 3.03; 95% CI: 1.67-5.48; P=0.0002). The high combined expression of TLR4 and MyD88 was also significantly associated with poor DFS and OS (HR: 2.25; 95% CI: 1.27-3.99; P=0.0053 and HR: 2.97; 95% CI: 1.64-5.38; P=0.0003). Multivariate analysis showed that high expressions of TLR4 (OS: adjusted HR: 1.88; 95% CI: 0.99-3.55; P=0.0298) and MyD88 (DFS: adjusted HR: 1.93; 95% CI: 1.01-3.67; P=0.0441; OS: adjusted HR: 2.25; 95% CI: 1.17-4.33; P=0.0112) were independent prognostic factors of OS. Furthermore, high co-expression of TLR4/MyD88 was strongly associated with both poor DFS and OS. CONCLUSION: Our findings suggest that high expression of TLR4 and MyD88 is associated with liver metastasis and is an independent predictor of poor prognosis in patients with CRC.

(Summary) Various mechanical stimuli affect differentiation of mesoderm-derived cells such as osteoblasts or myoblasts, suggesting that adipogenesis may also be influenced by mechanical stimulation. However, effects of mechanical stimuli on adipogenesis are scarcely known. Compressive force was applied to a human preadipocyte cell line, SGBS. Levels of gene expression were estimated by real-time reverse transcription-polymerase chain reaction. The accumulation of lipids was evaluated by Sudan III or Oil Red O staining. In SGBS cells subjected to a compressive force of 226 Pa for 12 h before adipogenic induction, adipogenesis was inhibited. Compressive force immediately after adipogenic induction did not affect the adipogenesis. The expression of peroxisome proliferator-activated receptor (PPAR) gamma2 and CCAAT/enhancer binding protein (C/EBP) alpha mRNA during adipogenesis was inhibited by compressive force, whereas C/EBPbeta and C/EBPdelta mRNA levels were unaffected. In preadipocytes, compressive force increased mRNA levels of Krüppel-like factor 2, preadipocyte factor 1, WNT10b, and cyclooxygenase-2 (COX-2) which are known as negative regulators for the PPARgamma2 and C/EBPalpha genes. Furthermore, a COX-2 inhibitor completely reversed the inhibition of adipogenesis by compressive force. In conclusion, compressive force inhibited adipogenesis by suppressing expression of PPARgamma2 and C/EBPalpha in a COX-2-dependent manner.

(Summary) Familial isolated pituitary adenoma (FIPA) is an autosomal dominant condition with variable genetic background and incomplete penetrance. Germline mutations of the aryl hydrocarbon receptor interacting protein (AIP) gene have been reported in 15-40% of FIPA patients. Limited data are available on the functional consequences of the mutations or regarding the regulation of the AIP gene. We describe a large cohort of FIPA families and characterize missense and silent mutations using minigene constructs, luciferase and beta-galactosidase assays, as well as in silico predictions. Patients with AIP mutations had a lower mean age at diagnosis (23.6+/-11.2 years) than AIP mutation-negative patients (40.4+/-14.5 years). A promoter mutation showed reduced in vitro activity corresponding to lower mRNA expression in patient samples. Stimulation of the protein kinase A-pathway positively regulates the AIP promoter. Silent mutations led to abnormal splicing resulting in truncated protein or reduced AIP expression. A two-hybrid assay of protein-protein interaction of all missense variants showed variable disruption of AIP-phosphodiesterase-4A5 binding. In summary, exonic, promoter, splice-site, and large deletion mutations in AIP are implicated in 31% of families in our FIPA cohort. Functional characterization of AIP changes is important to identify the functional impact of gene sequence variants.

(Summary) Cyclin-dependent kinase inhibitors represented by the INK4 family comprising p16(INK4A), p15(INK4B), p18(INK4C), and p19(INK4D) are regulators of the cell cycle shown to be aberrant in many types of cancer. Mice lacking p18(Ink4c) exhibit a series of phenotypes including the development of widespread organomegaly and pituitary adenomas. The objective of our study is to examine the role of p18(INK4C) in the pathogenesis of human pituitary tumors. The protein and mRNA levels of p18(INK4C) were examined by immunohistochemistry and real-time reverse transcription-polymerase chain reaction, respectively. The methylation status of the p18(INK4C) gene promoter and somatic mutations of the p18(INK4C) gene were also investigated. p18(INK4C) protein expression was lost or significantly reduced in 64% of pituitary adenomas compared with levels in normal pituitary glands. p18(INK4C) mRNA levels were low in all ACTH adenomas and non-functioning (NF)-FSH and in 42%, 70% and 66% of GH, PRL, and subtype 3 adenomas, respectively. p18(INK4C) mRNA levels were significantly associated with p18(INK4C) protein levels. Neither methylated promoters in pituitary adenomas, except in one NF-FSH adenoma, nor somatic mutations of the p18(INK4C) gene in any pituitary adenomas were detected. The down-regulation of p18(INK4C) expression may contribute to the tumorigenesis of pituitary adenomas.

(Summary) Obesity is considered a chronic low-grade inflammatory status and the stromal vascular fraction (SVF) cells of adipose tissue (AT) are considered a source of inflammation-related molecules. We identified YKL-40 as a major protein secreted from SVF cells in human visceral AT. YKL-40 expression levels in SVF cells from visceral AT were higher than in those from subcutaneous AT. Immunofluorescence staining revealed that YKL-40 was exclusively expressed in macrophages among SVF cells. YKL-40 purified from SVF cells inhibited the degradation of type I collagen, a major extracellular matrix of AT, by matrix metalloproteinase (MMP)-1 and increased rate of fibril formation of type I collagen. The expression of MMP-1 in preadipocytes and macrophages was enhanced by interaction between these cells. These results suggest that macrophage/preadipocyte interaction enhances degradation of type I collagen in AT, meanwhile, YKL-40 secreted from macrophages infiltrating into AT inhibits the type I collagen degradation.

(Summary) High-mobility group A2 is highly expressed during embryogenesis and in various benign and malignant tumors. Recent studies report that high-mobility group A2 is negatively regulated by the let-7 microRNAs (miRNAs) family in vitro. The development of pituitary adenomas in high-mobility group A2 transgenic mice showed that high-mobility group A2 may be involved in pituitary tumorigenesis. However, no studies have investigated the clinical significance of high-mobility group A2 and its relationship to the let-7 miRNA family in human pituitary adenomas. Using immunohistochemistry, we analyzed high-mobility group A2 expression with respect to various clinicopathologic factors in 98 pituitary adenomas. Overexpression of high-mobility group A2 was observed in 39% (38/98) of pituitary adenomas compared with normal adenohypophysial tissue and was frequently found in adenomas including prolactin (PRL), adrenocorticotrophic hormone, or follicle-stimulating hormone/luteinizing hormone and in null cell adenomas, but relatively rare in growth hormone (GH) and mixed GH/PRL adenomas. High-mobility group A2 expression was significantly associated with tumor invasion (P<0.05) and was significantly higher in grade IV than in grades I, II, and III adenomas (P<0.05). High levels of high-mobility group A2 expression were more frequently observed in macroadenomas than in microadenomas (P<0.05). High levels of high-mobility group A2 expression also significantly correlated with the proliferation marker Ki-67 (P<0.0001). Real-time quantitative RT-PCR analysis was carried out to evaluate the expression of let-7 in 55 pituitary adenomas. Subsequently, decreased expression of let-7 was confirmed in 23 of 55 (42%) adenomas and was correlated with high-grade tumors (P<0.05). An inverse correlation between let-7 and high-mobility group A2 expression was evident (R=-0.33, P<0.05). These findings support a causal link between let-7 and high-mobility group A2 whereby loss of let-7 expression induces high-mobility group A2 upregulation that represents an important mechanism in pituitary tumorigenesis and progression.

(Summary) Glycerol-3-phosphate acyltransferase 1 (GPAT1) is a rate limiting enzyme in de novo glycerophospholipid synthesis. The murine GPAT1 promoter sequence (the "classical" sequence) was reported previously. However, the organization of this DNA sequence does not fully match the mouse genome sequences on NCBI/GenBank. Here we have identified net cis-acting promoter sequences for the mouse GPAT1 gene: promoter 1a which includes part of the classical sequence and the downstream promoter 1b. Promoter 1a facilitates transcription of two alternative GPAT1 transcript variants, GPAT1-V1 and V2, while promoter 1b produces a third transcript variant, GPAT1-V3. Upstream stimulating factor-1 (USF-1) controlled both promoters whereas sterol regulatory element-binding protein-1 (SREBP-1) exclusively regulated promoter 1a activity in vitro. Feeding increased GPAT1-V1 and V2, but not V3 mRNA levels in mouse liver. The obese condition of db/db mice did not alter the hepatic expression levels of any of the three GPAT1 variants. Feeding enhanced hepatic mRNA levels, intranuclear protein levels and promoter 1a-binding levels of SREBP-1, but not of USF-1. Thus, promoter 1a was exclusively activated by routine feeding in vivo. Our results indicate differential roles of the two promoters in the regulation of hepatic GPAT1 gene expression in mice.

Grossman and Márta Korbonits : The role of the aryl hydrocarbon receptor-interacting protein gene in familial and sporadic pituitary adenomas., The Journal of Clinical Endocrinology and Metabolism, Vol.93, No.6, 2390-2401, 2008. (Summary) Mutations have been identified in the aryl hydrocarbon receptor-interacting protein (AIP) gene in familial isolated pituitary adenomas (FIPA). It is not clear, however, how this molecular chaperone is involved in tumorigenesis. AIP sequence changes and expression were studied in FIPA and sporadic adenomas. The function of normal and mutated AIP molecules was studied on cell proliferation and protein-protein interaction. Cellular and ultrastructural AIP localization was determined in pituitary cells. Twenty-six FIPA kindreds and 85 sporadic pituitary adenoma patients were included in the study. Nine families harbored AIP mutations. Overexpression of wild-type AIP in TIG3 and HEK293 human fibroblast and GH3 pituitary cell lines dramatically reduced cell proliferation, whereas mutant AIP lost this ability. All the mutations led to a disruption of the protein-protein interaction between AIP and phosphodiesterase-4A5. In normal pituitary, AIP colocalizes exclusively with GH and prolactin, and it is found in association with the secretory vesicle, as shown by double-immunofluorescence and electron microscopy staining. In sporadic pituitary adenomas, however, AIP is expressed in all tumor types. In addition, whereas AIP is expressed in the secretory vesicle in GH-secreting tumors, similar to normal GH-secreting cells, in lactotroph, corticotroph, and nonfunctioning adenomas, it is localized to the cytoplasm and not in the secretory vesicles. Our functional evaluation of AIP mutations is consistent with a tumor-suppressor role for AIP and its involvement in familial acromegaly. The abnormal expression and subcellular localization of AIP in sporadic pituitary adenomas indicate deranged regulation of this protein during tumorigenesis.

(Summary) The gene products of CDH13 and CDH1, H-cadherin and E-cadherin, respectively, play a key role in cell-cell adhesion. Inactivation of the cadherin-mediated cell adhesion system caused by aberrant methylation is a common finding in human cancers, indicating that the CDH13 and CDH1 function as tumor suppressor and invasion suppressor genes. In this study, we analyzed the expression of H-cadherin mRNA and E-cadherin protein in 5 normal pituitary tissues and 69 primary pituitary adenomas including all major types by quantitative real-time RT-PCR (qRT-PCR) and immunohistochemistry, respectively. Reduced expression of H-cadherin was detected in 54% (28/52) of pituitary tumors and was significantly associated with tumor aggressiveness (P<0.05). E-cadherin expression was lost in 30% (21 of 69) and significantly reduced in 32% (22 of 69) of tumors. E-cadherin expression was significantly lower in grade II, III, and IV than in grade I adenomas (P=0.015, P=0.029, and P=0.01, respectively). Using methylation-specific PCR (MSP), promoter hypermethylation of CDH13 and CDH1 was detected in 30 and 36% of 69 adenomas, respectively, but not in 5 normal pituitary tissues. Methylation of CDH13 was observed more frequently in invasive adenomas (42%) than in non-invasive adenomas (19%) (P<0.05) and methylation of CDH1 was more frequent in grade IV adenomas compared with grade I adenomas (P<0.05). Methylation of either CDH13 or CDH1 was identified in 35 cases (51%) and was more frequent in grade IV invasive adenomas than in grade I non-invasive adenomas (P<0.05 and P<0.05, respectively). Downregulation of expression was correlated with promoter hypermethylation in CDH13 and CDH1. In conclusion, the tumor-specific downregulation of expression and methylation of CDH13 and CDH1, alone or in combination, may be involved in the development and invasive growth of pituitary adenomas.

(Summary) Pituitary tumors are a diverse group of neoplasms that are classified based on clinical manifestations, hormone excess, and histomorphologic features. Those that cause growth hormone (GH) excess and acromegaly are subdivided into morphologic variants that have not yet been shown to have pathogenetic significance or predictive value for therapy and outcome. Here, we identify a selective somatic histidine-to-leucine substitution in codon 49 of the extracellular domain of the GH receptor (GHR) in a morphologic subtype of human GH-producing pituitary tumors that is characterized by the presence of cytoskeletal aggresomes. This GHR mutation significantly impairs glycosylation-mediated receptor processing, maturation, ligand binding, and signaling. Pharmacologic GH antagonism recapitulates the morphologic phenotype of pituitary tumors from which this mutation was identified, inducing the formation of cytoskeletal keratin aggresomes. This novel GHR mutation provides evidence for impaired hormone autofeedback in the pathogenesis of these pituitary tumors. It explains the lack of responsiveness to somatostatin analogue therapy of this tumor type, in contrast to the exquisite sensitivity of tumors that lack aggresomes, and has therapeutic implications for the safety of GH antagonism as a therapeutic modality in acromegaly.

(Summary) Parafibromin (PF) is a 531-amino acid protein encoded by HRPT2, a putative tumor suppressor gene recently implicated in the autosomal-dominant hyperparathyroidism-jaw tumor familial cancer syndrome and sporadic parathyroid carcinoma. To investigate effects of PF's overexpression on cell proliferation, we performed assays in four different cell lines. The transient overexpression of PF inhibited cell growth in HEK293 and NIH3T3 cells, but enhanced cell growth in the SV40 large T antigen-expressing cell lines such as 293FT and COS7 cells. In 293FT cells, PF was found to interact with SV40 large T antigen and its overexpression promoted entry into the S phase, implying that the interaction enhanced progression through the cell cycle. The tumor suppressor protein PF acts as a positive regulator of cell growth similar to an oncoprotein in the presence of SV40 large T antigen.

(Summary) Recently, germline mutations of aryl hydrocarbon receptor-interacting protein (AIP) gene located on 11q13 were identified in patients with pituitary adenoma predisposition. AIM/PATIENTS AND METHODS: We investigated the involvement of the AIP gene in one family with isolated familial somatotropinomas (IFS). To investigate the role of AIP in sporadic GH-secreting adenomas, we first analysed somatic mutations in 40 tumours. Second, DNA from corresponding leucocytes was analysed in tumours showing genetic changes of the AIP gene. Germline mutation of AIP was found in an IFS family. Bi-allelic inactivation of AIP by a combination of germline mutation and loss of heterozygosity were confirmed in two pituitary adenomas. Mutation analysis of the AIP gene in the 40 sporadic GH-secreting adenomas showed no mutations except for a missense mutation, suggesting that germline mutations in patients diagnosed with sporadic acromegaly or gigantism were rare. In a patient with gigantism, a missense mutation of V49M was identified at the germline level. Based on these results, we conclude that the loss of function of AIP contributes to IFS, but not for most Japanese sporadic GH-secreting adenomas.

(Summary) Hyperparathyroidism-jaw tumour (HPT-JT) syndrome is characterized by parathyroid tumours as well as by ossifying fibromas of the mandible and maxilla, renal cysts, or Wilms' tumours. Recently, the gene responsible for HPT-JT syndrome has been identified as the HRPT2 tumour suppressor gene. In an 18-year-old male, a tumour in the maxilla was first diagnosed as an ossifying fibroma. During biochemical screening before surgery, the patient received a diagnosis of primary hyperparathyroidism. Neck computed tomography scanning showed a parathyroid tumour. Surgical excisions to remove the jaw tumour and parathyroid adenoma were performed. The postoperative course has been uneventful and a follow up at 2 years revealed no evidence of recurrence. The HRPT2 germline mutation of 39delC was detected in the proband, but not in his unaffected parents. These results suggested that the germline mutation occurred de novo.

(Summary) A novel murine glycerol-3-phosphate acyltransferase-like protein 1 (named xGPAT1) has been cloned. The mouse xGPAT1 gene is located on mouse Chromosome 2, spans >19 kb, and consists of at least 23 exons. The protein is 32% identical and 72% similar to mouse mitochondrial GPAT (mtGPAT) on the amino acid level. Sequencing analysis confirmed that xGPAT1 has a 2403-bp open reading frame (ORF) that encodes an 801-amino acid protein with an estimated molecular mass of 89.1 kDa. A hydropathy plot of the deduced xGPAT1 protein showed a high degree of similarity with that of the mtGPAT protein. Using 5'-rapid amplification of cDNA ends, two alternate, untranslated exon 1 (1a and b) isoforms were obtained, generating variants xGPAT1-v1 and xGPAT1-v2. xGPAT1-v1 is expressed in mouse heart, liver, spleen, kidney and murine inner medullary collecting duct 3 (mIMCD3) cells, while xGPAT1-v2 is expressed in mouse liver, spleen, kidney, white and brown adipose tissues and 3T3-L1 pre- and post-adipocytes. xGPAT1 was distributed in the membrane fraction and showed GPAT activity when epitope-tagged xGPAT1 was expressed in Chinese hamster ovary (CHO)-K1 cells.

(Summary) A subset of familial isolated primary hyperparathyroidism (FIHP) is a variant of hyperparathyroidism-jaw tumour syndrome (HPT-JT). AIM/PATIENTS AND METHODS: We investigated the involvement of the HRPT2, MEN1 and CASR genes in 11 provisional FIHP families and two HPT-JT families. Germline mutations of HRPT2 were found in two of the 11 FIHP families and one of the two HPT-JT families. One FIHP family with parathyroid carcinoma and atypical adenomas and another FIHP family with cystic parathyroid adenoma had novel frameshift mutations of 518-521del and 62-66del, respectively. In a patient with HPT-JT, a de novo germline mutation of 39delC was detected. Novel somatic HRPT2 mutations of 70-73del and 95-102del were found in two of five parathyroid tumours in a family with a 518-521del mutation. Biallelic inactivation of HRPT2 by a combination of germline and somatic mutation was confirmed in the parathyroid tumours. The finding that two families diagnosed with FIHP carried HRPT2 mutations suggests that they have occult HPT-JT. In the remaining 10 families, one family had a missense MEN1 mutation. No mutations of CASR were detected. Our results confirm the need to test for HRPT2 in FIHP families, especially those with parathyroid carcinomas, atypical adenomas or adenomas with cystic change.

(Summary) Aberrant promoter methylation and resultant silencing of several tumor suppressor genes play an important role in the pathogenesis of many tumor types. The human Ras association domain family 1A gene (RASSF1A), recently cloned from the lung tumor locus at 3p21.3, was shown to be frequently inactivated by hypermethylation of its promoter region in a number of malignancies. We have investigated the expression and epigenetic changes of this novel universal tumor suppressor gene in pituitary adenomas and correlated the data with clinicopathologic findings. Fresh frozen normal pituitary tissues and 52 primary pituitary adenomas including all major types were examined. Methylation-specific polymerase chain reaction (MSP), combined bisulfite restriction analysis (COBRA), bisulfite sequencing and semiquantitative reverse transcription-polymerase chain reaction were used to analyze DNA promoter methylation status and the mRNA expression of RASSF1A, respectively. High levels of RASSF1A transcript and no methylation of the RASSF1A promoter were found in normal pituitary tissues. RASSF1A promoter methylation was detected in 20 of 52 (38%) adenomas including all major types of pituitary adenomas. However, a lower frequency of methylation of the RASSF1A promoter was found in gonadotroph cell adenomas (15%) compared with growth hormone cell, prolactin cell, or adrenocorticotropic hormone cell adenomas (54, 46 and 50%, respectively). Methylation frequency was higher in the most aggressive adenomas (87% in grade IV tumors, P=0.0163). In addition, methylation of the RASSF1A promoter potentially correlated with higher labeling index of the proliferation marker Ki-67 (P=0.1475). Loss or significant reduction of RASSF1A messenger RNA transcripts was identified in 18 of 20 (90%) adenomas with hypermethylation of RASSF1A (P<0.0001). Our data suggest that promoter hypermethylation of RASSF1A and resultant alterations of RASSF1A expression may play a critical role in pituitary tumorigenesis and may be involved in tumor progression.

(Summary) Although it is known that retinoic acid (RA) regulates the cellular differentiation of skin keratinocytes, the effects of RA on the anchoring junction have not been clarified. The effects of all-trans RA on cell-cell and cell-matrix connections of gingival epithelial (GE)1 cells in a multilayered culture were investigated. Ultrastructures of GE1 cells were observed and immunohistochemistry was used to detect keratin 4, keratin 13, and desmoglein expression. Reverse transcription-polymerase chain reaction was performed to detect expression of desmosome and hemidesmosome-associating adhesion molecules, keratin 13, and keratin14. Retinoic acid caused immunohistochemical diminution of keratin 4, keratin 13, and desmoglein. Ultrastructurally, RA induced drastic loss of typical desmosomes and complete loss of hemidesmosomes. RA significantly decreased the transcript levels of keratin 13, keratin 14, desmoglein 1, and desmocollin 1 in a dose-dependent manner. The 230-kD bullous pemphigoid antigen (BPAG1) gene expression was also reduced by RA, whereas transcript levels of integrin alpha6, integrin beta4, the 180-kD bullous pemphigoid antigen (BPAG2), and laminin 5 were not affected. These results indicated that RA disintegrated not only desmosomes by depriving the cells of desmoglein 1, desmocollin 1, keratin 13, and keratin 4, but also hemidesmosomes by reducing the expression of BPAG1 and keratin 14 in basal keratinocytes.

(Summary) To identify the genes that determine differentiation phenotypes, we compared gene expression of pancreatic islet beta- and alpha-cells, which are derived from the common precursor and secrete insulin and glucagon, respectively. The expression levels of homeotic genes including Hox genes known to determine region specificity in the antero-posterior (AP) body axis, tissue-specific homeobox genes, and other 8,734 genes were compared in a beta- and alpha-cell line of MIN6 and alpha TC1.6. The expression of homeotic genes were surveyed with reverse transcription-polymerase chain reaction (RT-PCR) using degenerate primers corresponding to invariant amino acid sequences within the homeodomain and subsequently with specific primers. Expression of Hoxc6, Hoxc9, Hoxc10, Pdx1, Cdx2, Gbx2, Pax4, and Hlxb9 genes in MIN6 was higher than those in alpha TC1.6, while expression of Hoxa2, Hoxa3, Hoxa5, Hoxa6, Hoxa7, Hoxa9, Hoxa10, Hoxa13, Hoxb3, Hoxb5, Hoxb6, Hoxb13, Hoxb8, and Brain4 genes in alpha TC1.6 was higher than those in MIN6. Out of 8,734 mouse genes screened with high-density mouse cDNA microarrays for MIN6- and alpha TC1.6-derived cDNA, 58 and 25 genes were differentially over- and under-expressed in MIN6, respectively. GLUTag, which is derived from a large bowel tumor and expresses the proglucagon gene, showed a comparatively similar expression profile to that of alpha TC1.6 in both homeotic and other genes analyzed in cDNA microarray. Our results are consistent with the interpretation that not only the tissue-specific homeotic genes, but also Hox genes are related to differentiation phenotypes of pancreatic beta- and alpha-cells rather than their regional specification of the body in vertebrates.

Setsuko Ii, Mika Ohta, Eiji Kudo, Takashi Yamaoka, Tomokazu Tachikawa, Maki Moritani, Mitsuo Itakura and Katsuhiko Yoshimoto : Redox State-Dependent and Sorbitol Accumulation-Independent Diabetic Albuminuria in Mice with Transgene-Derived Human Aldose Reductase and Sorbitol Dehydrogenase Deficiency., Diabetologia, Vol.47, No.3, 541-548, 2004. (Summary) We investigated the role played by sorbitol accumulation in the kidney in the development of diabetic albuminuria. We created mice ( hAR-Tg:SDH null) with transgene-derived human aldose reductase and sorbitol dehydrogenase (SDH) deficiency, and analysed (i). the contribution of accumulated sorbitol to urinary albumin excretion rate, and (ii). the effect of the aldose reductase inhibitor, epalrestat, on the diabetic redox state, including decreased renal reduced glutathione concentrations or increased lactate to pyruvate ratios in the diabetic kidney. Compared to littermates, non-diabetic transgenic mice had a 2.6-fold increase in aldose reductase mRNA. In a diabetic group, aldose reductase mRNA in hAR-Tg mice was 2.7-fold higher than in littermates. In the diabetic and non-diabetic groups, hAR-Tg:SDH null mice had the highest sorbitol content among all four genetic types including hAR-Tg:SDH null, SDH null, hAR-Tg and littermates. The urinary albumin excretion rate in non-diabetic groups was similar in the four genetic types of mouse. In diabetic groups it was greater than in non-diabetic groups, but did not correlate with the sorbitol content among the four genetic types of mouse. When aldose reductase inhibitor and streptozotocin were given simultaneously at 6 weeks of age, epalrestat prevented diabetic increases in urinary albumin excretion rate and completely prevented diabetic decreases in reduced glutathione concentrations and diabetic increases in lactate to pyruvate ratios, even in the presence of transgenic aldose reductase. The degree of diabetic albuminuria in genetically modified mice is dependent on the redox state and independent of polyol accumulation; aldose reductase inhibitor can prevent diabetic albuminuria by normalising diabetic redox changes.

(Summary) Although seed plants have gamma-tubulin, a ubiquitous component of centrosomes associated with microtubule nucleation in algal and animal cells, they do not have discrete microtubule organizing centers (MTOCs) comparable to animal centrosomes, and the organization of microtubule arrays in plants has remained enigmatic. Spindle development in basal land plants has revealed a surprising variety of MTOCs that may represent milestones in the evolution of the typical diffuse acentrosomal plant spindle. We have isolated and characterized the gamma-tubulin gene from a liverwort, one of the extant basal land plants. Sequence similarity to the gamma-tubulin gene of higher plants suggests that the gamma-tubulin gene is highly conserved in land plants. The G9 antibody to fission yeast gamma-tubulin recognized a single band of 55 kD in immunoblots from bryophytes. Immunohistochemistry with the G9 antibody clearly documented the association of gamma-tubulin with various MTOC sites in basal land plants (e.g., discrete centrosomes with and without centrioles and the plastid surface in monoplastidic meiosis of bryophytes). Changes in the distribution of gamma-tubulin occur in a cell cycle-specific manner during monoplastidic meiosis in the liverwort Dumortiera hirsuta. gamma-Tubulin changes its localization from the plastid surface in prophase I to the spindle, from the spindle to phragmoplasts and the nuclear envelope in telophase I, and back to the plastid surfaces in prophase II. In vitro experiments show that gamma-tubulin is detectable on the surface of isolated plastids and nuclei of D. hirsuta, and microtubules can be repolymerized from the isolated plastids. gamma-Tubulin localization patterns on plastid and nuclear surfaces are not affected by the destruction of microtubules by oryzalin. We conclude that gamma-tubulin is a highly conserved protein associated with microtubule nucleation in basal land plants and that it has a cell cycle-dependent distribution essential for the orderly succession of microtubule arrays.

(Summary) Components of cyclinD1/cyclin-dependent kinase 4 (CDK4)/p16INK4a/pRb pathway are the frequent target of many tumor types. We examined the role of retinoblastoma susceptibility gene (RB1) and the CDK4 gene in human pituitary tumorigenesis. For the RB1 gene, pRb expression and loss of heterozygosity (LOH) on 13q in pituitary adenomas were analysed. Immunostaining of pRb revealed lack of expression in 1 of 29 pituitary adenomas. In 4 of 31 pituitary adenomas, allelic imbalances including LOH of RB1 on 13q14 were detected. Three of 4 pituitary adenomas, in which one adenoma lacked pRb expression, had a common LOH region at least from D13S219 on 13q12.3-q13 to D13S265 on 13q31-32. Interphase fluorescence in situ hybridization with a probe of RB1 showed 2 copies of RB1 gene suggesting that mitotic recombination events, not deletion or chromosome loss, led to LOH in the 3 pituitary adenomas analyzed. All 27 exons, intron-exon boundaries, and essential promoter region of RB1 gene were then sequenced in genomic DNA from 4 pituitary adenomas with allelic imbalance on 13q14 including one adenoma without pRb expression and 3 adenomas with pRb expression. Any somatic mutations, insertions, or microdeletions in the RB1 gene were not detected in 4 pituitary adenomas. Methylation sensitive (MS)-polymerase chain reaction (PCR) and bisulfite sequencing analysis revealed hypomethylated status of CpG islands in the promoter region of the RB1 genes of 4 pituitary adenomas. In addition, activating mutations of CDK4 gene, which is a component of cyclinD1/CDK4/p16INK4a/pRb pathway, were not detected in 31 pituitary adenomas. Based on these results, it is concluded that somatic mutations of the RB1 gene or CDK4 gene do not appear to play a major role in pituitary tumorigenesis. This supports the presence of potential tumor suppressor gene(s) on 13q12.3-q13 to 13q31-32 in pituitary adenomas.

(Summary) The molecular events leading to the development of GH-secreting pituitary tumours remain largely unknown. Gsalpha (GNAS1) mutations are found in 27-43% of sporadic GH-secreting adenomas in the Caucasian population, but the frequency of GNAS1 mutations in Japanese and Korean acromegalic patients was reported to be lower, 4-9% and 16%, respectively. Other genes responsible for the tumourigenesis of GH-secreting pituitary adenomas have not been detected yet. PRKAR1A, which codes for the RIalpha regulatory subunit of cyclic AMP-dependent protein kinase A (PKA) on 17q23-24, was recently reported to contain inactivating mutations in some Carney complex families, which involved GH-secreting adenomas in about 10%. We re-evaluated the frequency of GNAS1 mutations and investigated PRKAR1A on the hypothesis that it might play a role in the tumourigenesis of GH-secreting adenomas. We analysed exons 8 and 9 of GNAS1 and all exons and the exon-intron boundaries of PRKAR1A with the PCR and by direct sequencing using genomic DNA extracted from 32 GH-secreting pituitary adenomas (30 GH-secreting adenomas, two GH and PRL-secreting adenomas) and 28 corresponding peripheral blood samples, and performed loss of heterozygosity (LOH) analysis of 17q23-24 with four microsatellite markers and intragenic markers of PRKAR1A. Seventeen of 32 (53.1%) tumours showed somatic-activating mutations of GNAS1: 16 (53.3%) of 30 GH-secreting adenomas and one of two GH and PRL-secreting adenomas. Neither inactivating somatic mutations of PRKAR1A nor LOH of 17q23-24 were detected in any of the tumours examined. We reconfirm the important role of activating mutations of GNAS1 in GH-secreting adenomas, and conclude that PRKAR1A does not play a significant role in the tumourigenesis.

(Summary) The cribriform-morular variant (C-MV), an unusual and peculiar subtype of papillary thyroid carcinoma (PTC), has been observed frequently in familial adenomatous polyposis (FAP)-associated thyroid carcinoma and also in sporadic thyroid carcinoma. In this paper, five young women with the C-MV of PTC, aged 22-34 years at cancer diagnosis, are reported; two of them had attenuated FAP. Grossly, one FAP-associated tumour and one sporadic tumour were multicentric and the others were solitary. Histologically, the tumours were encapsulated and exhibited a combination of cribriform, follicular, trabecular, solid, and papillary patterns of growth, with morular areas. Immunohistochemically, the tumour cells showed cytoplasmic expression of thyroglobulin, neuron-specific enolase, epithelial membrane antigen, high- and low-molecular-weight cytokeratins, vimentin, and bcl-2 protein; nuclear expression of oestrogen and progesterone receptors, and retinoblastoma protein; and cytoplasmic and nuclear accumulation of beta-catenin. Germline mutations of the adenomatous polyposis coli (APC) gene were investigated using the protein truncation test in four subjects, including two FAP individuals. Germline APC mutation was identified in only one FAP patient with the multicentric C-MV of PTC, who had a thymidine deletion at codon 512, resulting in a frameshift leading to a premature stop codon. No loss of heterozygosity of loci close to the APC gene was detected in tumour tissues from these four patients. Somatic mutation analysis of exon 3 of the beta-catenin gene (CTNNB1) revealed alterations in seven tumours from all five individuals: one at a serine residue (codon 29), three at amino acids adjacent to serine or threonine residues (codons 22, 39, and 44), and three at other amino acids (codons 49, 54, and 56). Moreover, each of two different tumours examined from two patients with the multicentric C-MV of PTC, had different somatic mutations of the CTNNB1 gene. Taken together, these data suggest that accumulation of mutant beta-catenin contributes to the development of the C-MV of PTC.

(Summary) We report an unusual case of spindle epithelial tumor with thymus-like differentiation (SETTLE) of the thyroid present in a 6-year-old boy. The tumor, located at both the left lobe and isthmus, was a circumscribed mass with slightly gritty whorled appearance. Microscopically, the lobulated, highly cellular, spindle cell neoplasm was arranged in intersecting bundles and fascicles separated by fibrous bands. Benign-appearing glands entrapped within fibrous bands and foci of squamous differentiation within spindle cells were observed. Immunohistochemically, the spindle cells were diffusely positive for cytokeratins, vimentin, and alpha-smooth muscle actin and patchily reactive for muscle-specific actin and epithelial membrane antigen, exhibiting myoepithelial differentiation. The spindle cells were also patchily immunopositive for p53 protein. Molecular genetic analysis revealed Ki-ras gene mutations at codons 13 (GGC(gly) to AGC(ser)) and 15 (GGC(gly) to AGC(ser)) on the same allele. Mutation of the p53 gene was not detected. This is the first report on Ki-ras oncogene mutations in a case of SETTLE.

(Summary) E-cadherin/catenin complex regulates cellular adhesion and motility and is believed to function as an invasion suppressor system. In a number of cancers, abnormal and reduced expression of E-cadherin/catenin complex is associated with tumor invasion and metastasis. Prolactinomas show frequent invasion on the surrounding structures, despite their histologically benign nature. Furthermore, gender-based differences in endocrine and surgical findings are found in patients with prolactinoma. To understand biological factors governing prolactinoma behavior, this study analyzed the expression of E-cadherin; alpha-, beta-, and gamma-catenins; p120; and cell proliferation marker MIB-1 labeling index in 13 invasive tumors (9 in men, 4 in women), 26 noninvasive tumors (4 in men, 22 in women), and 8 normal anterior pituitaries by immunohistochemistry. Immunostaining of E-cadherin; alpha-, beta-, and gamma-catenins; and p120 showed a membranous pattern of reactivity and generally stronger in normal pituitaries than in prolactinomas. Expression of E-cadherin and beta-catenin was significantly lower in invasive than in noninvasive prolactinomas (P <.002 and P <.005, respectively), and reduced expression of E-cadherin and beta-catenin was more frequent in invasive than in noninvasive prolactinomas (P <.001 and P <.05, respectively); in contrast, gamma-catenin expression showed higher in invasive than in noninvasive prolactinomas (P <.05). Expression of E-cadherin was significantly lower in macroprolactinomas than in microprolactinomas (P <.01), and decreased expression of E-cadherin and beta-catenin predicted high MIB-1 expression (P <.05). Moreover, the expression of E-cadherin and beta-catenin was significantly lower in macroprolactinomas in men than in those in women (P <.01 and P <.02, respectively). No statistical correlations were observed between expression of alpha-catenin, p120, and clinicopathologic features. In conclusion, the reduction of E-cadherin and beta-catenin expression was related to invasiveness and proliferative status of prolactinomas and correlated with the more aggressive behavior of prolactinomas in men compared with in women.

(Summary) We report three sporadic parathyroid tumors with biallelic inactivation of the multiple endocrine neoplasia type 1 (MEN1) gene. Three parathyroid tumors had two somatic mutations (K119del and 864del8, 363insT and 1767delT, and 508del33 and W341X, respectively). The mutations in both alleles detected by long-range polymerase chain reaction and subcloning in three tumors would likely result in a nonfunctional menin protein in parathyroid glands. These results show that the MEN1 gene is inactivated not only by a combination of somatic mutations and loss of heterozygosity, but also by somatic double mutations located on different alleles. The results directly confirmed the participation of MEN1 in the tumorigenesis of sporadic parathyroid tumors.

(Summary) The cadherin-catenin complex regulates cellular adhesion and motility, and genetic alterations in these molecules play a critical role in multistage tumorigenesis. In this study, the expression of three major type I classic cadherins E-, N-, and P-cadherin and their undercoat proteins alpha-, beta-, and gamma-catenin, and pp120 was investigated in 127 pituitary adenomas and 10 normal adenohypophyseal glands using an immunohistochemical technique with highly specific monoclonal antibodies. In normal pituitary glands, E-cadherin, catenins, and pp120 were strongly expressed on almost all hormone-producing cell-cell boundaries, N-cadherin was weakly immunoreactive on a few cell-cell boundaries, and P-cadherin was negative. In pituitary adenomas, a correlation was not identified among expression of E-cadherin, catenins, or pp120 with patient age, sex, hormone level, tumor size, and/or invasiveness, respectively. Expression of E-cadherin, catenins, and pp120 was significantly reduced in 24 growth hormone (GH) cell adenomas with prominent fibrous bodies compared with the other subtypes of pituitary adenomas and normal pituitary glands (p < 0.0001, respectively). Methylation-specific polymerase chain reaction analysis revealed that the E-cadherin gene promoter region was methylated in 6 of 16 (37.5%) GH cell adenomas with prominent fibrous bodies examined, 2 of which displayed total methylation, but not in 10 GH cell adenomas without fibrous bodies. No mutation of exon 3 of the beta-catenin gene was found in 16 GH cell adenomas with prominent fibrous bodies or in 10 other subtypes of pituitary adenomas that showed unremarkable intracellular presence of beta-catenin protein. In conclusion, the decreased expression of the E-cadherin catenin complex and methylation of the E-cadherin gene promoter region only in GH cell adenomas with prominent fibrous bodies may be an event associated with the formation of fibrous bodies.

(Summary) Neuroendocrine tumors (NETs) of the gastrointestinal tract comprise a heterogeneous group of neoplasms arising from the diffuse neuroendocrine system. These tumors strongly differ from each other on the basis of different pathogenetic, clinical, functional, histological, and prognostic patterns. Previous studies have shown that abnormal and reduced expression of the E-cadherin/catenin complex in several human cancers is associated with tumor dedifferentiation, advanced clinical stages, and poor survival rate. We assessed correlations between the expression of E-cadherin and catenins, Ki-67, and the following clinicopathological factors: age, embryological site of origin, size, histological growth pattern, the depth of penetration into the intestinal wall, and the presence of metastasis. In this study, reduction of membranous E-cadherin expression to a variable degree was detected in more than two-thirds (42 of 51) of gastrointestinal NETs (19 foregut, 8 midgut, and 24 hindgut) belonging to the complete neuroendocrine neoplastic spectrum [18 well-differentiated NETs, 22 well-differentiated neuroendocrine carcinomas (NECs), and 11 poorly differentiated NECs]. The reduction of E-cadherin expression was concomitant with the reduction of alpha-catenin (44 of 51) and beta-catenin (35 of 51) expression. Our immunohistochemical analysis demonstrated significant differences of percentage of membranous positive cells of E-cadherin, alpha-catenin, or beta-catenin between normal tissues and well-differentiated NETs (P=0.0038, P=0.004, and P=0.0329, respectively), well-differentiated NECs (P<0.001, P<0.001, and P<0.001, respectively) and poorly differentiated NECs (P=0.0002, P<0.0002, and P=0.0002, respectively). Among the gastrointestinal NETs, there were significantly more positive cells of E-cadherin, alpha-catenin, or beta-catenin in well-differentiated NETs than well-differentiated NECs (P=0.0006, P=0.0065, and P=0.0001, respectively) or poorly differentiated NECs (P=0.0053, P=0.0041, and P<0.001, respectively). MIB-1 labeling index generally showed a low proliferative activity in well-differentiated NETs (0.49+/-0.37) and well-differentiated NECs (0.662+/-0.66). A high proliferation rate was observed in poorly differentiated NECs (41.518+/-16.59). MIB-1 labeling index was significantly higher in poorly differentiated NECs than well-differentiated NETs and well-differentiated NECs (P<0.0001 and P<0.0001, respectively). E-cadherin, alpha-catenin, and beta-catenin expression were correlated significantly with transmural tumor invasion (P<0.0001, P=0.0001, and P<0.0001, respectively) and with size (P=0.0013, P=0.0001, and P<0.0001, respectively). These results indicate that the alteration in the E-cadherin/catenin expression may be involved in the growth and progression of gastrointestinal NETs.

(Summary) Overexpression of the cyclin D1 oncogene and inactivation of the p53 tumor suppressor have both been implicated in substantial proportions of sporadic human breast cancers. Transgenic mice with cyclin D1 overexpression targeted to mammary tissue by the MMTV enhancer-promoter have been shown to develop mammary cancers. To investigate the relationship between pathways driven by cyclin D1 overexpression and p53 loss during the development of breast cancers, we crossed MMTV-cyclin D1 mice with p53 heterozygous null (p53+/-) mice. In such crossed mice, cyclin D1-driven mammary neoplasia would need to be substantially accelerated by p53 loss in order for mammary tumors to develop prior to the expected onset of non-mammary tumors characteristic of the p53-deficient background alone. Instead, in mice heterozygous or homozygous for p53 deficiency and simultaneously carrying the MMTV-cyclin D1 transgene, only tumors typically found in p53-deficient mice developed and mammary tumors were not observed. Interestingly, MMTV-cyclin D1/p53+/- mice appeared to develop these non-mammary tumors more rapidly than p53+/- mice, and a majority of the sampled non-mammary tumors from MMTV-cyclin D1/p53+/- mice showed 'ectopic' expression of the MMTV-driven cyclin D1 transgene. Within the constraints of possible genetic background effects and limited sensitivity due to the early emergence of non-mammary tumors, these observations provide no evidence that inactivation of p53 confers a major additional selective advantage to mammary cells overexpressing cyclin D1 in this animal model of human breast cancer. Interestingly, the results do raise the possibility that p53 inactivation might complement or cooperate with cyclin D1 deregulation during the development of some types of non-mammary tumors.

(Summary) The relationship between abnormal cell proliferation and aberrant control of hormonal secretion is a fundamental and poorly understood issue in endocrine cell neoplasia. Transgenic mice with parathyroid-targeted overexpression of the cyclin D1 oncogene, modeling a gene rearrangement found in human tumors, were created to determine whether a primary defect in this cell-cycle regulator can cause an abnormal relationship between serum calcium and parathyroid hormone response, as is typical of human primary hyperparathyroidism. We also sought to develop an animal model of hyperparathyroidism and to examine directly cyclin D1's role in parathyroid tumorigenesis. Parathyroid hormone gene regulatory region--cyclin D1 (PTH--cyclin D1) mice not only developed abnormal parathyroid cell proliferation, but also developed chronic biochemical hyperparathyroidism with characteristic abnormalities in bone and, notably, a shift in the relationship between serum calcium and PTH. Thus, this animal model of human primary hyperparathyroidism provides direct experimental evidence that overexpression of the cyclin D1 oncogene can drive excessive parathyroid cell proliferation and that this proliferative defect need not occur solely as a downstream consequence of a defect in parathyroid hormone secretory control by serum calcium, as had been hypothesized. Instead, primary deregulation of cell-growth pathways can cause both the hypercellularity and abnormal control of hormonal secretion that are almost inevitably linked together in this common disorder.

(Summary) To examine the effect of overexpressed regenerating gene (Reg) I on pancreatic beta-cells, we generated transgenic mice expressing Reg I in islets (Reg-Tg mice). Three lines of Reg-Tg mice were established. In line-1 Reg-Tg mice, the expression level of Reg I mRNA in islets was 7 times higher than those in lines 2 and 3 of Reg-Tg mice, and line 1 mice developed diabetes by apoptosis of beta-cells, as well as various malignant tumors. In addition to the decrease in beta-cells, compensatory islet regeneration and proliferation of ductal epithelial cells were observed in line-1 Reg-Tg mice. Because Reg I protein was secreted primarily into pancreatic ducts from acinar cells, it may primarily stimulate the proliferation of ductal epithelial cells, and not beta-cells, and their differentiation into islets. Moreover, the tumor-promoting activity of Reg I protein should be considered for its possible clinical applications.

(Summary) Both endocrine and exocrine cells of the pancreas differentiate from epithelial cells of primitive pancreatic ducts, and four types of pancreatic islet cells (alpha, beta, delta, and PP cells) are derived from the common pluripotent precursor cells. Although Pa x 6 is expressed in all islet cells, Pa x 4 is detected only in beta cells. In homozygous Pa x 4-null mice, beta cells are absent, whereas the number of alpha cells is increased. Therefore, we hypothesized that the balance of Pa x 4 and 6 is one of the determinants by which the common progenitor cells differentiate into alpha or beta cells. To change this balance, we generated transgenic mice overexpressing Pa x 6 driven by the insulin promoter or the PDX1 promoter. In both types of transgenic mice, normal development of beta cells was disturbed, resulting in apoptosis of beta cells and diabetes. In Insulin/Pa x 6-Tg mice, beta cells were specifically affected, whereas in PDX/Pa x 6-Tg mice, developmental abnormalities involved the whole pancreas including hypoplasia of the exocrine pancreas. Furthermore, PDX/Pa x 6-Tg mice experienced proliferation of both ductal epithelia and islet cells and subsequent cystic adenoma of the pancreas. These findings suggest that Pa x 6 promotes the growth of ductal epithelia and endocrine progenitor cells and that the suppression of Pa x 6 is necessary for the normal development of beta cells and the exocrine pancreas.

(Summary) We cloned a full-length mouse cDNA and its human homologue encoding a novel protein designated as "SR-25." In Northern blot analysis, SR-25 mRNA was expressed in all organs tested, and relatively abundant in testis and thymus. Deduced amino acid sequences of mouse SR-25 and human SR-25 showed 77.7% identity. SR-25 has a serine-arginine repeat (SR repeat) and two types of amino acid clusters: a serine cluster and a highly basic cluster. Based on the presence of many nuclear localizing signals and a similarity to RNA splicing proteins, SR-25 is strongly suggested to be a nuclear protein and may contribute to RNA splicing.

(Summary) Using a human growth hormone reporter system, the introduced mutations in GG1 alone or both GG elements of GG1 and GG2 in the human insulin promoter abolished 94 or 96% of the beta-cell-specific transcriptional activity in a pancreatic islet beta-cell line of MIN6, while the mutations in GG2 or its total deletion abolished 85 or 86% of the transcriptional activity. When linked to the thymidine kinase promoter, mutations in GG1 or both GG elements abolished 74% of the transcriptional activity in MIN6 cells, while the mutations in GG2 or its total deletion abolished 55 or 54%. In the electrophoretic mobility shift assay (EMSA), one nuclear factor was shown to interact with two GG elements, and another C1-binding factor with GG1 and C1. The differential effects of deletions or selective mutations in the GG2 or GG1 sequence in the oligonucleotide probes on the binding activity of GG- or C1-binding factors in EMSA proved the requirement of both GG1 and GG2 or both GG1 and C1, respectively, for the transaction of these two factors. The molecular size of the GG-binding factor was estimated about 30 kDa. Based on these, we conclude that two GG elements contribute, with GG1 more critically than GG2, to the beta-cell-specific transcription of the human insulin gene through transaction with the GG- and C1-binding factors.

(Summary) RET is a receptor tyrosine kinase expressed in neuroendocrine cells and tumors. RET is activated by a ligand complex comprising glial cell line-derived neurotrophic factor (GDNF) and GDNF receptor-alpha (GDNFR-alpha). Activating mutations of the RET proto-oncogene were found in multiple endocrine neoplasia (MEN) 2 and in sporadic medullary thyroid carcinoma and pheochromocytoma of neuroendocrine origin. Mutations of the RET proto-oncogene and the glial cell line-derived neurotrophic factor (GDNF) gene were examined in human pituitary tumors. No mutations of the RET proto-oncogene including the cysteine-rich region or codon 768 and 918 in the tyrosine kinase domain were detected in 172 human pituitary adenomas either by polymerase chain reaction (PCR)-single strand conformation polymorphism (SSCP) or by PCR-restriction fragment length polymorphism (RFLP). Further, somatic mutations of the GDNF gene in 33 human pituitary adenomas were not detected by PCR-SSCP. One polymorphism of the GDNF gene at codon 145 of TGC or TGT was observed in a prolactinoma. The RET proto-oncogene message was detected in a normal human pituitary gland or 4 of 4 human pituitary adenomas with reverse transcription (RT)-PCR, and in rodent pituitary tumor cell lines with Western blotting. The expression of GDNF gene was detected in 1 of 4 human somatotroph adenomas, 1 of 2 corticotroph adenomas, and 2 of 6 rodent pituitary tumor cell lines with RT-PCR. Based on these, it is concluded that somatic mutations of the RET proto-oncogene or the GDNF gene do not appear to play a major role in the pituitary tumorigenesis in examined tumors.

(Summary) To investigate the role of tumor suppressor genes in sporadic pituitary adenomas, we first analyzed loss of heterozygosity on 11q13 with microsatellite analysis in 31 tumors. Loss of heterozygosity on 11q13 was detected in 1 mixed GH/PRL adenoma, and the somatic 22-bp deletion of the multiple endocrine neoplasia type 1 (MEN1) gene encoding menin was detected in this tumor. Trisomy 11 suggested by the decreased mean allelic ratios of 66% or 65% for 16 or 13 microsatellite markers, respectively, in 2 of 31 pituitary adenomas was confirmed by interphase fluorescence in situ hybridization. Screening for mutations of the MEN1 gene did not find mutations with PCR-single strand conformation polymorphism analysis in other pituitary adenomas retaining heterozygosity on 11q13. Based on these, it is concluded that inactivation of the MEN1 gene comprises a rare etiology for tumorigenesis of the pituitary gland, and that trisomy 11 or another gene(s) may contribute to the pathogenesis of sporadic pituitary adenomas.

(Summary) Familial isolated primary hyperparathyroidism (FIHP) is a rare hereditary disorder. We present four patients from a single family with FIHP, and genetic analysis of their parathyroid adenomas and parathyroid carcinoma. DNA was extracted from tumours resected at surgery. Tumours were examined for loss of heterozygosity (LOH) with microsatellite polymorphic markers. The 27-year-old proband (Patient 1) died of parathyroid carcinoma with metastases to the lungs and chest wall. Sixteen years later, his 34-year-old sister (Patient 2) presented with a neck tumour and primary hyperparathyroidism. Family screening revealed parathyroid tumours in his 36-year-old sister (Patient 3) and 29-year-old cousin (Patient 4). Histological examination of resected tumours showed parathyroid carcinoma and adenoma in Patient 2, a parathyroid adenoma in Patient 3, and an atypical parathyroid adenoma in Patient 4. Autopsy of the proband ruled out multiple endocrine neoplasia (MEN) type 1, and the three patients who underwent parathyroidectomy did not exhibit any abnormalities in the pancreas or the pituitary gland. Analysis of tumour DNA from one parathyroid carcinoma (Patient 2), the atypical parathyroid adenoma (Patient 4), and two parathyroid adenomas (Patients 2 and 3) showed limited LOH on chromosomes 13q12.3-q32 in an adenoma of Patient 2 and 9p21-p22 and 13q12.3-q32 in an adenoma of Patient 3. These results suggest the possible contribution of tumour suppressor genes including the retinoblastoma gene and the hereditary breast cancer susceptibility gene (BRCA2) on 13q to parathyroid tumours in this family.

(Summary) We report a case of multiple endocrine neoplasia type 1 who had repeated hypoglycemic episodes and had previously been diagnosed with bipolar manic-depressive disorder. The patient had a positive family history of multiple endocrine neoplasia type 1 and had multiple pancreatic endocrine tumors, hyperparathyroidism and possibly a pituitary tumor. The pancreatic tumors were resected by subtotal pancreatectomy and examined by histochemical staining and gene analysis. The tumor cells were positive for immunoreactive insulin and glucagon. A microsatellite polymorphism analysis revealed loss of heterozygosity on 11q13 in the tumors. By polymerase chain reaction-based nucleotide sequencing, we identified a germline mutation 483del2 of the MEN1 gene in the normal pancreatic tissue of the patient. This mutation causes a shift of the reading frame of menin mRNA at codon 125. It seems that the wild type allele of the MEN1 gene had been lost in the tumor cells whereas the mutant allele remained intact. This is the first identified MEN1 gene mutation in Japanese families and is different from all MEN1 gene mutations reported previously.

(Summary) A 52-year-old man with a past history of a pituitary adenoma and hyperparathyroidism due to a parathyroid adenoma was admitted because of a solitary tumour of the pancreas revealed by ultrasonography. His family history was unremarkable. Plasma glucagon levels were slightly elevated (280 ng/l, normal range, 40-180 ng/l) with decreased plasma amino acid levels. Plasma glucagon levels disclosed an exaggerated response during an arginine infusion test and paradoxical elevation during a 75 g oral glucose tolerance test. Endoscopic ultrasonography revealed a monolocular cystic mass of about 3 cm in diameter in the body of the pancreas. A pancreatic tumour was diagnosed before surgery as a cystic glucagonoma. Intra-operative ultrasonography showed one cystic mass in the body of pancreas and two other solid tumours, about 1 cm and 0.5 cm in diameter, in the tail of the pancreas. Histologically, all three tumours showed neoplastic epithelial cells with round nuclei forming cords and/or a ribbon-like arrangement. They showed positive staining for Grimelius' silver stain and immunopositive cells for glucagon. Genetic analysis of the main cystic tumour revealed loss of heterozygosity (LOH) on chromosome 11. After the operation, the responses of plasma glucagon to arginine infusion and oral glucose became normal. Here we describe the usefulness of these provocation tests for early diagnosis and post-operative follow-up in a rare cystic glucagonoma associated with multiple endocrine neoplasia type 1 (MEN 1) which had LOH on chromosome 11.

(Summary) In this and previous studies, we have shown p53 overexpression immunohistochemically in 14 of 17 porokeratotic specimens obtained from 14 lesions of nine cases, and in all six specimens of squamous cell carcinoma (SCC) arising on porokeratotic lesions of two cases. We screened mutations in exons 5 to 10 of the p53 gene in all these specimens by polymerase chain reaction-single strand conformation polymorphism analysis. Mutations of the p53 gene were detected in two of the six SCCs but not in any of the 17 porokeratotic specimens. These two mutations were C to T transitions at codons 146 and 175 in exon 5, which were a nonsense mutation at a dipyrimidine site and a missense mutation at a CG site, respectively. To our knowledge, neither of these mutations has been identified in skin cancers before. Our observations indicate that mutations of the p53 gene are not the major molecular etiology for porokeratosis, but are related to its skin carcinogenesis, and that p53 overexpression in porokeratosis is not due to p53 gene mutations.

(Summary) Sixteen sporadic pheochromocytomas, 3 pheochromocytomas in neurofibromatosis 1, and 4 pheochromocytomas in multiple endocrine neoplasia (MEN) 2A or 2B were screened for mutations at codon 768 of the RET proto-oncogene by AluI digestion of polymerase chain reaction PCR products and mutations in exon 13 by PCR-single strand conformation polymorphism (SSCP) analysis. Although mutations at codon 768 (GAG --> GAC; Glu --> Asp) of the RET proto-oncogene were recently reported to be found in 40% of sporadic medullary thyroid carcinomas (MTCs), the absence of missense mutations at codon 768 was confirmed both with PCR-restriction fragment length polymorphism (RFLP) and PCR-SSCP analysis in all examined cases of pheochromocytomas. These results suggest that mutations at codon 768 of the RET proto-oncogene do not represent a frequent mechanism of tumorigenesis for both sporadic and hereditary pheochromocytomas.

(Summary) To establish a practical method of somatic gene therapy, we aimed to develop a regulatory system at the cellular level using a suicide vector. We introduced the herpes simplex virus type 1 thymidine kinase (HSV-tk) gene into the human proinsulin-producing Ltk-cells and examined whether ganciclovir (GCV) administration could control proinsulin production in vivo. The cells transfected with the HSV-tk gene showed more than 100-fold increase in sensitivity to GCV compared with the parent cells. Analysis of blood glucose in diabetic nude mice with transplanted cells showed that proinsulin production by these cells was strongly suppressed by GCV treatment in vivo as reflected by the reversal to hyperglycemia. However, in the in vivo experiment, the plasmid containing the HSV-tk gene was spontaneously lost from the transplanted cells in one of six cases resulting in the resistance to GCV as reflected by the persistent hypoglycemia and increased tumor size. This system of HSV-tk and administration of GCV may be applicable to gene therapy as a suicide vector, but the system of stable expression of the HSV-tk gene must be established.

(Summary) Genomic structure of rat amidophosphoribosyltransferase (ATase; EC 2.4.2.14), which catalyzes the first committed step in de novo purine nucleotide synthesis, was determined by polymerase chain reaction (PCR)-based methods. There are 11 exons and all exon-intron boundaries were conserved among rat, human, and chicken ATase genes. A rat aminoimidazole ribonucleotide carboxylase (AIRC) cDNA encoding a bifunctional enzyme of AIRC (EC 4.1.1.21) at step 6 and SAICAR synthetase (EC 6.3.2.6) at step 7 in de novo purine nucleotide synthesis was cloned and sequenced. The size of the cloned rat AIRC cDNA was 1329 bp, and amino acid identity with human and chicken AIRC was 96 and 85%, respectively. The intergenic sequence using a phage clone and the PCR product disclosed that ATase and AIRC genes are physically linked with the 736 bp sequence between the translation start sites, and the determination of the transcriptional start sites by the primer extension assay for these genes disclosed that distance between the two major transcriptional start sites is 585 bp. The amount of mRNAs of both genes showed approx. 5-6-fold increase in G1/S phase of the cell cycle over those in G0 phase in synchronized rat 3Y1 fibroblasts.

(Summary) Medullary thyroid carcinoma (MTC) and pheochromocytoma appear in either a sporadic or a hereditary form as components of multiple endocrine neoplasia (MEN). Many germline mutations of the RET proto-oncogene have been reported in patients with MEN 2A and 2B, and familial MTC (FMTC). To elucidate the etiological roles in tumorigenesis of sporadic MTCs and pheochromocytomas, mutations in the cysteine-rich region of the RET proto-oncogene were analyzed by using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) analysis. Exons 10 and 11 were studied in genomic DNAs from 3 clinically apparent sporadic MTCs, MTCs and pheochromocytomas from 2 patients with MEN 2A, 1 with FMTC, 4 with MEN 2B, 3 with neurofibromatosis type 1 (NF1), 12 sporadic pheochromocytomas and an MTC cell line, TT. All tumors from two patients with MEN 2A and one patient with FMTC had mutations at codon 618 and 634 as well as their leukocytes, reflecting their germline mutations. In this region, no mutations were detected in any tumors from patients with MEN 2B and NF1, and sporadic pheochromocytomas. But mutations were detected and identified in 3 clinically apparent sporadic MTCs and TT cells. A 6 base pair (bp) deletion causing the loss of a cysteine residue at codon 634 and a mutation causing substitution from cysteine to tyrosine at codon 634 were detected in 2 sporadic MTCs as somatic events. In a female patient diagnosed as having sporadic MTC, a mutation at codon 618 was detected not only in tumor tissues, but also in her leukocytes, suggesting a germline mutation of the RET proto-oncogene.(ABSTRACT TRUNCATED AT 250 WORDS) (Keyword) Adrenal Gland Neoplasms / Aged / Alleles / Base Sequence / Carcinoma, Medullary / Cysteine / DNA, Neoplasm / Exons / Female / Germ-Line Mutation / Humans / Leukocytes / Male / Middle Aged / Molecular Sequence Data / Pheochromocytoma / Polymerase Chain Reaction / Proto-Oncogenes / Thyroid Neoplasms / Tumor Cells, Cultured (Tokushima University Institutional Repository) ● Metadata: 111692 (Link to Publication Site) ● Publication site (DOI): 10.1507/endocrj.42.517 (Link to Search Site for Scientific Articles) ● PubMed @ National Institutes of Health, US National Library of Medicine (PMID): 8556059 ● Search Scopus @ Elsevier (PMID): 8556059 ● Search Scopus @ Elsevier (DOI): 10.1507/endocrj.42.517 (Tokushima University Institutional Repository: 111692, DOI: 10.1507/endocrj.42.517, PubMed: 8556059)

(Summary) The clinical and genetic features of a 43-year-old male patient with multiple endocrine neoplasia type 1 were reported. He developed hyperparathyroidism, a GHRH-producing pancreatic tumor, and acromegaly between 1980 and 1983. Because his pituitary gland increased in size even after resecting the GHRH-producing pancreatic tumor, transsphenoidal hypophysectomy was performed six years later. The pituitary contained two histologically-different adenomas composed of somatotroph cells and null cells. Genetic analyses revealed loss of heterozygosity on chromosome 11 in common in the pituitary adenomas, the pancreatic endocrine tumors, and a parathyroid hyperplasia. On the other hand, mutations of ras, p53, Gs alpha, and Gi2 alpha genes were not found in these tumors. The loss of the tumor suppressor gene on chromosome 11q12-13 was involved in the formation of two pituitary adenomas, two pancreatic endocrine functioning tumors, and a parathyroid hyperplasia in this patient, but the tumorigenic factors in the specific endocrine organs remain to be studied.

(Summary) Sporadic pheochromocytomas, sporadic medullary thyroid carcinomas (MTCs), pheochromocytomas and/or MTCs in multiple endocrine neoplasia (MEN) 2A or 2B were screened for mutations in the tyrosine kinase domain of the RET proto-oncogene by direct sequencing of PCR-amplified products or sequencing subcloned DNAs from PCR-products. All tumors of 4 MEN 2B patients were confirmed to contain a heterozygous missense mutation at codon 918 (ATG-->ACG; Met-->Thr) of the RET proto-oncogene as well as their leukocytes. The same tumor-specific mutations at codon 918 were also found in 5/16 (31%) sporadic pheochromocytomas. These results suggest that mutations of the RET proto-oncogene in its tyrosine kinase domain play a role not only as the predisposing gene for MEN 2B, but also as a tumorigenic factor for pheochromocytomas of sporadic type.

(Summary) Since 1968, a total of 23 patients with multiple endocrine neoplasia type 2B (MEN 2B) have been identified in Japan. The mean age at diagnosis was 20.3 years (range, 6 to 39 years). All patients had neuromas and bumpy lips. All patients underwent thyroidectomy for medullary thyroid carcinoma (MTC). Ten of 23 patients had pheochromocytomas. One patient died of cerebral bleeding at the age of 43, 2 patients died of MTC at the age of 35 and 12. Five-, 10-, and 15-year survival rates were 100%, 92%, and 88%, respectively. The clinical course of MTC in MEN 2B in Japanese is not so aggressive when compared with about a 50% 10-year survival reported for Caucasians. Genetic analysis of 4 MTC and 1 pheochromocytoma from 4 patients with MEN 2B revealed no common changes in regard to loss of heterozygosity on 21 chromosomes or point mutations of the ras, Gs alpha, or p53 genes.

(Summary) The Gs alpha (Gs alpha) gene can be activated to the putative oncogene gsp by specific point mutations at codons 201 or 227. Such mutations have been reported in growth hormone (GH)-secreting pituitary adenomas and thyroid tumors. To clarify the role of Gs alpha gene in human endocrine tumors, 197 tumors were screened for point mutations at codons 201 or 227 of the Gs alpha gene. Mutations were detected by primer-introduced restriction analysis (PIRA) of the polymerase chain reaction (PCR) product of genomic DNA. These Gs alpha mutations were present in 4 of 53 pituitary adenomas (4 of 43 GH-secreting adenomas; 1 of these 4 was a GH- and prolactin-secreting adenoma from a patient with familial multiple endocrine neoplasia Type 1), 4 of 66 thyroid tumors (4 of 30 papillary carcinomas), and 1 of 19 adrenocortical adenomas (1 of 6 aldosterone-secreting adenomas). In contrast, none of these Gs alpha mutations were detected in parathyroid tumors, endocrine pancreatic tumors, or pheochromocytomas. Gs alpha mutations at these two loci may play a role in the pathogenesis of a small population of GH-secreting pituitary adenomas, papillary thyroid carcinomas, and adrenocortical adenomas, but that they are not involved in the pathogenesis of other types of endocrine tumors.

(Summary) The genetic and molecular basis of a mutant prothrombin of 'prothrombin Tokushima' was studied by polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and PCR-restriction fragment length polymorphism (PCR-RFLP) analyses. The abnormal gene was detected by altered migration by PCR-SSCP and by the loss of an MspI site by PCR-RFLP. The gene for prothrombin Tokushima was shown to be inherited from the mother of the proband. Sequencing analysis using PCR-amplified genomic DNA clarified a substitution of thymine (T) for cytosine (C) at position 9,490, changing arginine (Arg) to tryptophan (Trp) at position 418 of the polypeptide chain. This point mutation is assumed to be the molecular basis of prothrombin Tokushima, firstly, because of the absence of distinct changes in Southern blot analysis of the proband's DNA (using a full-length human prothrombin cDNA as a probe), secondly, because it has the same molecular weight as the abnormal gene product, and, thirdly, because of the absence of other amino acid abnormalities in the proteolytic peptide-fragments. It is concluded that PCR-SSCP and PCR-RFLP were useful for detecting the abnormal gene and for directly diagnosing the carrier status of dysprothrombinemia. This is the first report of gene analysis of dysprothrombinemia.

(Summary) The quantity of translatable mRNA of glucose-6-phosphate dehydrogenase (D-glucose-6-phosphate: NADP+ 1-oxidoreductase, EC 1.1.1.49) in primary cultures of adult rat hepatocytes subjected to different hormonal conditions was determined with a reticulocyte-lysate, cell-free system. The level of glucose-6-phosphate dehydrogenase mRNA was about 5-fold higher in the presence of insulin than in its absence. This increase of glucose-6-phosphate dehydrogenase mRNA reached a maximum 12 h after the addition of insulin. The maximum level of induction of glucose-6-phosphate dehydrogenase mRNA required 10(-8) M insulin. Glucagon and triiodothyronine had no effect on the glucose-6-phosphate dehydrogenase mRNA level. The increase of glucose-6-phosphate dehydrogenase activity correlated with the increase in level of mRNA of this enzyme. This suggests that the changes in glucose-6-phosphate dehydrogenase activity in response to the above hormonal changes are primarily due to changes in the amount of mRNA coding for this enzyme.

(Summary) Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant disorder characterized by the combined occurrence of parathyroid, pancreatic endocrine, and anterior pituitary tumors. MEN1 has two characteristics; a hormone excess and a sometimes lethal outcome due to malignant tumors. The recent identification of the MEN1 gene has opened the door to a much deeper understanding of this syndrome. Germline MEN1 mutations have been identified in most MEN1 families. They were not found, however, in families with familial pituitary tumors. Thus, studies with the MEN1 gene helped to establish that mutation of some other gene(s) is likely causative of the MEN1 phenocopy. These recent advances provide for the identification of mutant MEN1 gene carriers who are at a high risk of developing MEN1. The protein encoded by the MEN1 gene has been shown to function in the regulation of JunD-activated transcription but much still remains to be elucidated.

(Summary) 家族性成長ホルモン(GH)産生腺腫家系5家系を対象とてし，癌抑制遺伝子aryl hydrocarbon receptor-interating protein(AIP)異常の解析を行った．いずれの家系においてもカーニー複合体の症候はみられなかった．白血球からゲノムDNAを抽出し，AIP,MEN1,PRKAR1A,p27Kip1遺伝子の塩基配列を同定した．5家系において，API,MEN1,PRKAR1A,p27Kip1遺伝子の胚細胞変異はみられなかった．AIP遺伝子のプロモーター部位遺伝子では1家系においてC-270-269CG>AA及びC.911G>Aの変化がみられ，これは日本人対照78名にはみられなかった．家族性副甲状腺機能亢進症はMEN1の亜型の可能性があるため，9家系についてp27Kip1の遺伝子を解析したが，胚細胞変異はみられなかった．1家系においてc.165A>Gの一塩基多型がみられた．家族性GH産生腺腫発症にはAIP,MRN1,PRKAR1A,p27Kip1以外の遺伝子変化が関与している可能性が高いと考えられた． (Keyword) 血統癌抑制遺伝子多発性内分泌腫瘍1型 Cyclin-Dependent Kinase Inhibitor p27 下垂体腺腫-成長ホルモン産生(遺伝学) Aryl Hydrocarbon Receptor Nuclear Translocator PRKAR1A遺伝子ヒト (Tokushima University Institutional Repository) ● Metadata: 114160 (Tokushima University Institutional Repository: 114160)
