Shintaro Inoue, Takahito Watanabe, Taiki Hamaguchi, Yoshiyasu Ishimaru, Katsuyuki Miyawaki, Takeshi Nikawa, Akira Takahashi, Sumihare Noji and Taro Mito : Combinatorial expression of ebony and tan generates body color variation from nymph through adult stages in the cricket, Gryllus bimaculatus., PLoS ONE, Vol.18, No.5, 2023. (要約) Insect body colors and patterns change markedly during development in some species as they adapt to their surroundings. The contribution of melanin and sclerotin pigments, both of which are synthesized from dopamine, to cuticle tanning has been well studied. Nevertheless, little is known about how insects alter their body color patterns. To investigate this mechanism, the cricket Gryllus bimaculatus, whose body color patterns change during postembryonic development, was used as a model in this study. We focused on the ebony and tan genes, which encode enzymes that catalyze the synthesis and degradation, respectively, of the precursor of yellow sclerotin N-β-alanyl dopamine (NBAD). Expression of the G. bimaculatus (Gb) ebony and tan transcripts tended to be elevated just after hatching and the molting period. We found that dynamic alterations in the combined expression levels of Gb'ebony and Gb'tan correlated with the body color transition from the nymphal stages to the adult. The body color of Gb'ebony knockout mutants generated by CRISPR/Cas9 systemically darkened. Meanwhile, Gb'tan knockout mutants displayed a yellow color in certain areas and stages. The phenotypes of the Gb'ebony and Gb'tan mutants probably result from an over-production of melanin and yellow sclerotin NBAD, respectively. Overall, stage-specific body color patterns in the postembryonic stages of the cricket are governed by the combinatorial expression of Gb'ebony and Gb'tan. Our findings provide insights into the mechanism by which insects evolve adaptive body coloration at each developmental stage.

(要約) Although butterflies undergo a dramatic morphological transformation from larva to adult via a pupal stage (holometamorphosis), crickets undergo a metamorphosis from nymph to adult without formation of a pupa (hemimetamorphosis). Despite these differences, both processes are regulated by common mechanisms that involve 20-hydroxyecdysone (20E) and juvenile hormone (JH). JH regulates many aspects of insect physiology, such as development, reproduction, diapause, and metamorphosis. Consequently, strict regulation of JH levels is crucial throughout an insect's life cycle. However, it remains unclear how JH synthesis is regulated. Here, we report that in the corpora allata of the cricket, Gryllus bimaculatus, Myoglianin (Gb'Myo), a homolog of Drosophila Myoglianin/vertebrate GDF8/11, is involved in the down-regulation of JH production by suppressing the expression of a gene encoding JH acid O-methyltransferase, Gb'jhamt In contrast, JH production is up-regulated by Decapentaplegic (Gb'Dpp) and Glass-bottom boat/60A (Gb'Gbb) signaling that occurs as part of the transcriptional activation of Gb'jhamt Gb'Myo defines the nature of each developmental transition by regulating JH titer and the interactions between JH and 20E. When Gb'myo expression is suppressed, the activation of Gb'jhamt expression and secretion of 20E induce molting, thereby leading to the next instar before the last nymphal instar. Conversely, high Gb'myo expression induces metamorphosis during the last nymphal instar through the cessation of JH synthesis. Gb'myo also regulates final insect size. Because Myo/GDF8/11 and Dpp/bone morphogenetic protein (BMP)2/4-Gbb/BMP5-8 are conserved in both invertebrates and vertebrates, the present findings provide common regulatory mechanisms for endocrine control of animal development.

Y Kadomura-Ishikawa, Katsuyuki Miyawaki, Akira Takahashi, Toshiya Masuda and Sumihare Noji : Light and abscisic acid independently regulated FaMYB10 in Fragaria x ananassa fruit, Planta, Vol.241, No.4, 953-965, 2015. (要約) Light and ABA independently regulated anthocyanin biosynthesis via activation of FaMYB10 expression. FaMYB10 accelerated anthocyanin synthesis of pelargonidin 3-glucoside and cyanidin 3-glucoside during strawberry fruit ripening. Light is an integral factor in fruit ripening. Ripening in non-climacteric fruit is also effected by the plant hormone abscisic acid (ABA). However, how light and/or ABA regulate fruit ripening processes, such as strawberry color development remains elusive. Results of the present study showed light and ABA regulated strawberry fruit coloration via activation of FaMYB10 expression, an R2R3 MYB transcription factor. Light exposure increased FaMYB10 transcript levels, flavonoid pathway genes, and anthocyanin content. Exogenous ABA promoted FaMYB10 expression, and anthocyanin content, accompanied by increased ABA-responsive transcript levels and flavonoid pathway genes. ABA biosynthesis inhibitor treatment, and RNAi-mediated down-regulation of the ABA biosynthetic gene (9-cis epoxycarotenoid dioxygenase: FaNCED1), and ABA receptor (magnesium chelatase H subunit: FaCHLH/ABAR) showed inverse ABA effects. Furthermore, additive effects were observed in anthocyanin accumulation under combined light and ABA, indicating independent light and ABA signaling pathways. FaMYB10 down-regulation by Agrobacterium-mediated RNA interference (RNAi) in strawberry fruits showed decreased pelargonidin 3-glucoside and cyanidin 3-glucoside levels, accompanied by consistent flavonoid pathway gene expression levels. FaMYB10 over-expression showed opposite FaMYB10 RNAi phenotypes, particularly cyanidin 3-glucoside synthesis by FaMYB10, which was correlated with FaF3'H transcript levels. These data provided evidence that light and ABA promoted FaMYB10 expression, resulting in anthocyanin accumulation via acceleration of flavonoid pathway gene expression. Finally, our results suggested FaMYB10 serves a role as a signal transduction mediator from light and ABA perception to anthocyanin synthesis in strawberry fruit.

Qing-Ri Jin, Yukiko Bandou, Katsuyuki Miyawaki, Yosuke Shikama, Chisato Kosugi, Nanako Aki, Makoto Funaki and Sumihare Noji : Correlation of fibroblast growth factor 21 serum levels with metabolic parameters in Japanese subjects, The Journal of Medical Investigation : JMI, Vol.61, No.1.2, 28-34, 2014. (要約) Since serum level of fibroblast growth factor 21 (FGF21) has been implicated as a potential biomarker for the early detection of the metabolic syndrome and type 2 diabetes, we examined how FGF21 serum levels are correlated with metabolic parameters in Japanese subjects. FGF21 levels were analyzed by enzyme-linked immunosorbent assays. Spearman's correlation and multiple stepwise regression analyses were used to examine the relationship between serum FGF21 and other factors. A Mann-Whitney U test was performed between the normal and high groups for triglycerides and systolic blood pressure (BP) respectively. By univariate correlation analysis, serum FGF21 levels were significantly associated with triglyceride levels, systolic BP, diastolic BP, pulse pressure, body mass index (BMI), age, fasting plasma glucose (FPG) levels, and total cholesterol levels. Multiple regression analysis (adjusted for age, gender, and BMI) showed that serum FGF21 levels were independently and significantly associated with triglyceride levels and systolic BP. Serum FGF21 levels were significantly higher in subjects with high triglyceride levels and high systolic BP compared with those who had normal triglyceride levels and normal systolic BP respectively. This study found that FGF21 levels might be a biomarker for some metabolic disorders associated with metabolic syndrome.

Y Kadomura-Ishikawa, Katsuyuki Miyawaki, Sumihare Noji and Akira Takahashi : Phototropin 2 is involved in blue light-induced anthocyanin accumulation in Fragaria x ananassa fruits, Journal of Plant Research, Vol.126, No.6, 847-857, 2013. (要約) Anthocyanins are widespread, essential secondary metabolites in higher plants during color development in certain flowers and fruits. In strawberries, anthocyanins are also key contributors to fruit antioxidant capacity and nutritional value. However, the effects of different light qualities on anthocyanin accumulation in strawberry (Fragaria x ananassa, cv. Sachinoka) fruits remain elusive. In the present study, we showed the most efficient increase in anthocyanin content occurred by blue light irradiation. Light sensing at the molecular level was investigated by isolation of two phototropin (FaPHOT1 and FaPHOT2), two cryptochrome (FaCRY1 and FaCRY2), and two phytochrome (FaPHYA and FaPHYB) homologs. Expression analysis revealed only FaPHOT2 transcripts markedly increased depending on fruit developmental stage, and a corresponding increase in anthocyanin content was detected. FaPHOT2 knockdown resulted in decreased anthocyanin content; however, overexpression increased anthocyanin content. These findings suggested blue light induced anthocyanin accumulation, and FaPHOT2 may play a role in sensing blue light, and mediating anthocyanin biosynthesis in strawberry fruits. This is the first report to find a relationship between visible light sensing, and color development in strawberry fruits.

(要約) Traditional methods used to study strawberry ripening-related gene function are time-consuming, and require at least 15 months from initiating the transformation experiment until the first ripe fruits are available for analysis. To accelerate data acquisition during gene function studies, we explored a transient assay method that employs an Agrobacterium-mediated RNAi (AmRNAi) technique in post-harvest strawberry fruit, Fragaria×ananassa (Fa) cv. Sachinoka, a Japanese cultivar. Our results showed that artificial white light induced strong expression of Fa chalcone synthase (Fa CHS), Fa chalcone isomerase (Fa CHI), and Fa flavonoid 3 -hydroxylase orthologues (Fa F3 H) in post-harvest fruit. Fa CHS and Fa F3 H function was subsequently examined by performing AmRNAi with post-harvest fruit. Although reduction of light-induced Fa F3 H expression by AmRNAi resulted in no significant change in anthocyanin content, reduction of Fa CHS significantly decreased anthocyanin levels, and up-regulated Fa F3 H levels. Our results are consistent with previous data indicating that while CHS is required for anthocyanin accumulation during late stage strawberry fruit maturation, Fa F3 H is not required. The novel system described here enabled gene function data to be available within 10 days of initiating the incubation period following infiltration. Therefore, we conclude our system is a valuable tool to elucidate the molecular mechanisms underlying light-induced ripening of strawberry fruit.

Noha Dabour, Tetsuya Bando, Taro Nakamura, Katsuyuki Miyawaki, Taro Mito, Hideyo Ohuchi and Sumihare Noji : Cricket body size is altered by systemic RNAi against insulin signaling components and epidermal growth factor receptor., Development Growth & Differentiation, Vol.53, No.7, 857-869, 2011. (要約) A long-standing problem of developmental biology is how body size is determined. In Drosophila melanogaster, the insulin/insulin-like growth factor (I/IGF) and target of rapamycin (TOR) signaling pathways play important roles in this process. However, the detailed mechanisms by which insect body growth is regulated are not known. Therefore, we have attempted to utilize systemic nymphal RNA interference (nyRNAi) to knockdown expression of insulin signaling components including Insulin receptor (InR), Insulin receptor substrate (chico), Phosphatase and tensin homologue (Pten), Target of rapamycin (Tor), RPS6-p70-protein kinase (S6k), Forkhead box O (FoxO) and Epidermal growth factor receptor (Egfr) and observed the effects on body size in the Gryllus bimaculatus cricket. We found that crickets treated with double-stranded RNA (dsRNA) against Gryllus InR, chico, Tor, S6k and Egfr displayed smaller body sizes, while Gryllus FoxO nyRNAi-ed crickets exhibited larger than normal body sizes. Furthermore, RNAi against Gryllus chico and Tor displayed slow growth and RNAi against Gryllus chico displayed longer lifespan than control crickets. Since no significant difference in ability of food uptake was observed between the Gryllus chico(nyRNAi) nymphs and controls, we conclude that the adult cricket body size can be altered by knockdown of expressions of Gryllus InR, chico, Tor, S6k, FoxO and Egfr by systemic RNAi. Our results suggest that the cricket is a promising model to study mechanisms underlying controls of body size and life span with RNAi methods.

(要約) Genetic variants of the transcription factor 7-like 2 (TCF7L2) gene affect the risk of type 2 diabetes in populations with multiple ethnic groups. However, a comprehensive survey of this gene has not been done for a Japanese population. Thus, we conducted this gene-based association study, in which the common genetic variants were analyzed. Using 24 Japanese type 2 diabetic subjects, we first screened a 9.5 kb region, which included the entire coding sequence, to assess potential functional variants of TCF7L2. Sequencing revealed a common coding variant (Pro477Thr) in exon 14 of TCF7L2 that was not enrolled in the public SNP database. Nineteen SNPs and the microsatellite DG10S478 were genotyped across the gene in 2,877 unrelated Japanese subjects. This independent screen identified the previously reported rs7903146 with a strongest association (allele P = 0.0001, odds ratio = 1.59 [95% confidence interval 1.25-2.01]), but there was no significant association between Pro477Thr and type 2 diabetes (allele P = 0.64). Expression of the Pro477Thr variant did not alter TCF7L2 expression in 30 lymphoblast cells. Although a genotypic effect of Pro477Thr on expression of TCF7L2 was not apparent, Pro477Thr was identified as a common variant of TCF7L2 in 2,877 Japanese subjects. Further functional studies are required to determine the possible effect of this coding variant on type 2 diabetes.

(要約) In an attempt to rectify the hyperglycemic state in obese insulin resistant db/db mice, a transgenic line was generated (db/db-CDK4(R24C)) that expresses a constitutively active form of cyclin-dependent kinase 4 (CDK4/R24C) under the control of the insulin promoter. Compared with non-transgenic db/db littermates, adult db/db-CDK4(R24C) mice show near-complete glycemic normalization and improved plasma lipid concentrations, but are also more susceptible to weight gain and have significantly lower plasma adiponection levels. They have striking islet hypertrophy and beta-cell hyperplasia, and retain an insulin secretory response during the glucose tolerance test. We examined the expression of several key regulatory transcription factor genes involved in lipid and glucose metabolism in insulin target tissues of db/db-CDK4(R24C) as well as db/db mice, and found that the expression levels of members of the peroxisome proliferator-activated receptor (PPAR) family are highly associated with metabolic alterations in a gene- and tissue-specific manner. We show for the first time that the Ppar-delta in skeletal muscle and white adipose tissues is transcriptionally down-regulated in db/db mice. The db/db-CDK4(R24C) mice present a novel model of leptin-resistant obesity with compensatory hyperinsulinemia and normalized blood glucose levels, and thus may be useful for future studies that aim to dissect relationships between insulin and leptin signaling.

(要約) Krüppel-like factor 11 (KLF11) is a transcriptional factor of the zinc finger domain family that regulates the expression of insulin. In North European populations, its common functional variant Q62R (rs35927125) is a strong genetic factor for Type 2 diabetes (P = 0.00033, odds ratio for G allele = 1.29, 95% CI 1.12-1.49). We examined the contribution of KLF11 variants to the susceptibility to Type 2 diabetes in a Japanese population. By re-sequencing Japanese individuals (n = 24, partly 96), we screened all four exons, exon/intron boundaries and flanking regions of KLF11. Verified single nucleotide polymorphisms (SNPs) were genotyped in 731 initial samples (369 control and 362 case subjects). Subsequently, we tested for association in 1087 samples (524 control and 563 case subjects), which were collected in different districts of Japan from the initial samples. We identified eight variants, including a novel A/C variant on intron 3, but no mis-sense mutations. In an association study, we failed to find any significant result of SNPs (minor allele frequency 8.2-46.2%) after correcting for multiple testing. Similarly, no haplotypes were associated with Type 2 diabetes. It is notable that the G allele in rs35927125 was completely absent in 1818 Japanese individuals. Genetic variants in KLF11 are unlikely to have a major effect of Type 2 diabetes in the Japanese population, although they were significantly associated in North European populations. These observations might help to determine the role of KLF11 variants in Type 2 diabetes in different populations.

Yukiko Yamashita, Hiroshi Inoue, Keshavarz Parvaneh, Katsuyuki Miyawaki, Yuka Nagasaki, Maki Moritani, Kiyoshi Kunika, Naoto Nakamura, Toshikazu Yoshikawa, Natsuo Yasui, Hiroshi Shiota, Toshihito Tanahashi and Mitsuo Itakura : SNPs in the KCNJ11-ABCC8 gene locus are associated with type 2 diabetes and blood pressure levels in the Japanese population., Journal of Human Genetics, Vol.52, No.10, 781-793, 2007. (要約) Many genetic association studies support a contribution of genetic variants in the KCNJ11-ABCC8 gene locus to type 2 diabetes (T2D) susceptibility in Caucasians. In non-Caucasian populations, however, there have been only a few association studies, and discordant results were obtained. Herein, we selected a total of 31 SNPs covering a 211.3-kb region of the KCNJ11-ABCC8 locus, characterized the patterns of linkage disequilibrium (LD) and haplotype structure, and performed a case-control association study in a Japanese population consisting of 909 T2D patients and 893 control subjects. We found significant associations between eight SNPs, including the KCNJ11 E23K and ABCC8 S1369A variants, and T2D. These disease-associated SNPs were genetically indistinguishable because of the presence of strong LD, as found previously in Caucasians. For the KCNJ11 E23K variant, the most significant association was obtained under a dominant genetic model (OR 1.32, 95% CI 1.09-1.60, P = 0.004). A meta-analysis of East Asian studies, comprising a total of 3,357 T2D patients (77.4% Japanese) and 2,836 control subjects (77.8% Japanese), confirmed the significant role of the KCNJ11 E23K variant in T2D susceptibility. Furthermore, we found evidence suggesting that the KCNJ11 E23K genotype is independently associated with higher blood-pressure levels.

(要約) The human GDD1/TMEM16E gene has been found to be mutated in gnathodiaphyseal dysplasia, an unusual skeletal syndrome with autosomal dominant inheritance. The molecular and biochemical function(s) of GDD1 protein has not yet been elucidated. In this study, we examined the murine GDD1 gene expression pattern during embryonic development, and characterized the cellular and tissue localizations of its gene product using a GDD1-specific antibody. In the developing embryos, GDD1 mRNA expression was principally associated with differentiating and developing somites, with a highly complex spatiotemporal pattern that involved the myotomal and sclerotomal lineages of somites. Biochemical studies indicated that GDD1 protein is an integral membrane glycoprotein that resides predominantly in intracellular vesicles. Immunohistochemical analysis showed a high level of murine GDD1 protein expression in cardiac and skeletal muscle tissues, and in growth-plate chondrocytes and osteoblasts in bone. These observations suggest diverse cellular role(s) of GDD1 in the development of musculoskeletal system.

(要約) The GPR119 was recently shown to be activated by oleoylethanolamide (OEA), a naturally occurring bioactive lipid with hypophagic and anti-obesity effects. In this study, we have cloned and characterized its murine counterpart, Gpr119. The full-length cDNA contained an open reading frame of 1008bp encoding a 335-amino acid protein. The genomic organization of Gpr119 was unique, having a 3'-untranslated second exon that was also involved in an alternative splicing event. Gene expression analyses confirmed its specific expressions in pancreatic islets and two endocrine cell-lines, MIN6 and alphaTC1. Immunohistochemistry and double-immunofluorescence studies using a specific antibody revealed the predominant Gpr119 localization in pancreatic polypeptide (PP)-cells of islets. No definitive evidence of Gpr119-immunoreactivity in adult beta- or alpha-cells was obtained. The Gpr119 mRNA levels were elevated in islets of obese hyperglycemic db/db mice as compared to control islets, suggesting a possible involvement of this receptor in the development of obesity and diabetes.

(要約) Early embryogenesis of the two-spotted cricket Gryllus bimaculatus was examined by scanning electron microscopy and several fluorescence staining methods, with special reference to these four issues: (i) the location of micropyles; (ii) the transfer of the female pronucleus following meiosis; (iii) the timing of cellularization; and (iv) the process of the germ primordium formation. Between two and four micropyles lie in the mid-ventral region of the egg. The egg nucleus is at the mid-dorsal periphery of the new laid egg, and meiosis resumes and is completed there. The female pronucleus moves to the mid-ventral side, and fertilization occurs there. Energid starts to proliferate and migrates to the periphery of the egg, initiating blastoderm formation. Actin caps surround each superficial nucleus. Cellularization occurs during the blastoderm stage. At a late blastoderm stage, nuclei aggregate in both the posterolateral patch-like regions of the egg to form a germ primordium. The germ primordium looks like a pair of dumbbells. Both the patches shift towards the ventral side and fuse into a germ primordium. The germ primordium contracts to produce a clearly delineated germ band. Observations on distribution patterns of F-actin indicate that, all through the process, the germ primordium retains that unity, and is not separated into two parts.
