(要約) Measuring glucose uptake in the skeletal muscle in vivo is an effective method to determine glucose metabolism abnormalities as the skeletal muscle is the principal tissue responsible for glucose disposal and is a major site of peripheral insulin resistance. In this study, we investigated the pathological glucose metabolism dynamics of the skeletal muscle of C57BL/6J mice in a noninvasive and time-sequential manner using positron emission tomography/computed tomography (PET/CT), an imaging technique that uses radioactive substances to visualize and measure metabolic processes in the body, with [ (出版サイトへのリンク) ● Publication site (DOI): 10.1016/j.bbrc.2020.05.165 (文献検索サイトへのリンク) ● PubMed @ National Institutes of Health, US National Library of Medicine (PMID): 32513534 ● Search Scopus @ Elsevier (PMID): 32513534 ● Search Scopus @ Elsevier (DOI): 10.1016/j.bbrc.2020.05.165 (DOI: 10.1016/j.bbrc.2020.05.165, PubMed: 32513534)

(要約) We established patient-like models of lung cancer metastasis by orthotopically implanting human non-small cell lung cancer cell lines into SCID mice. We evaluated the utilities of small-animal computed tomography (CT) and positron-emission tomography-computed tomography (PET/CT) in these models to non-invasively and repeatedly monitor the anticancer effects of cisplatin and erlotinib. We orthotopically implanted three non-small cell lung cancer cell lines, A549, FT821 and PC-9, into SCID mice. These mice were then divided into three groups: Control, cis-diamminedichloroplatinum (II) (CDDP) (7-mg/kg CDDP, single administration intraperitoneally), and erlotinib (25 mg/kg erlotinib/day, oral administration 5 days/week). After treatment initiation, we repeatedly performed PET/CT and CT measurements and assessed anticancer effects based on tumor volumes and FDG uptake. A549 tumors were not affected by CDDP or erlotinib. FT821 tumors were highly responsive to CDDP. PC-9 tumors, which have an epidermal growth factor receptor mutation, were highly responsive to erlotinib. Histological results and metastatic rates correlated with the anticancer effects shown by CT. In our orthotopic SCID mouse lung cancer models, 18FDG-PET/CT and CT imaging non-invasively and repeatedly monitored the efficacies of cisplatin and erlotinib against not only implanted tumors, but also mediastinal lymph node metastases.

(要約) A new scintillation imaging material [scintillator-silica fine powder (FP)] was prepared using silica FPs and scintillator-encapsulating silica nanoparticles (NPs) (scintillator-silica NPs). The wt% values of scintillator-silica NPs on the scintillator-silica FPs were 38, 43, 36 and 44%. Scintillation images of 3H, 63Ni, 35S, 33P, 204Tl, 89Sr and 32P dropped on the scintillator-silica FPs were obtained at about 37 kBq per 0.1-10 µl with a charge-coupled device (CCD) imager for a 5 min exposure. In particular, high-intensity CCD images of 35S were selectively obtained using the 2.25, 4.77 and 10 µm silica FPs with scintillator-silica NPs owing to the residual S of dimethyl sulfoxide in the preparation. Scintillation images of 3H at 1670 ± 9 Bq/0.5 µl and 347 ± 6 Bq/0.5 µl dropped in a 2 mm hole on the scintillator-silica FPs (6.78 and 10 µm) were also obtained using the CCD imager for a 2 h exposure.

(要約) We administered an angiotensin-converting enzyme inhibitor (captopril) to mice implanted with a human lung adenocarcinoma epithelial cell line (A549 cells) and investigated the tumor growth-inhibitory effect of captopril from the viewpoint of glucose metabolism using (18)F-fluorodeoxyglucose ((18)F-FDG)-PET/CT. Subcutaneous implantation of A549 cells (1.9×10(6) cells) was carried out in the lower right flank of mice. Fifteen days after the transplantation of A549 cells, mice (six in each group) were treated with captopril (3.0 mg/mouse) or saline (1000 μl/mouse) for 5 days. We performed (18)F-FDG-PET/CT imaging of the mice before and after the treatment and evaluated the degree of (18)F-FDG accumulation in tumors. In both groups (the captopril-administrated and control groups), values for the metabolic tumor volume (MTV), maximum standardized uptake value, total lesion glycolysis, and tumor volume after treatment had a tendency to increase. However, tumor growth was suppressed in the captopril-administrated group compared with the control group. In terms of the growth rate, the MTV and tumor volume were significantly different (P<0.05). It was found that captopril exerted a potential tumor growth-inhibitory effect; this was because the captopril-administrated group showed low values of MTV, maximum standardized uptake value, total lesion glycolysis, and tumor volume in comparison with the control group.

(要約) Recent epidemiological and animal studies have suggested that excess intake of phosphate (Pi) is a risk factor for the progression of chronic kidney disease and its cardiovascular complications. However, little is known about the impact of dietary high Pi intake on the development of metabolic disorders such as obesity and type II diabetes. In this study, we investigated the effects of dietary Pi on glucose and lipid metabolism in healthy rats. Male, 8-wk-old Sprague-Dawley rats were divided into 3 groups and given experimental diets containing varying amounts of Pi, i.e. 0.2% (low Pi, LP), 0.6% (control Pi, CP), and 1.2% (high Pi, HP). After 4 weeks, HP group showed lower visceral fat accumulation compared with other groups, accompanied by a low respiratory exchange ratio (VCO2/VO2) without alteration of locomotive activity. HP group had lower levels of plasma insulin and non-esterified fatty acids. In addition, HP group also showed suppressed expression of hepatic lipogenic genes including sterol regulatory element binding protein-1c, fatty acid synthase, and acetyl-CoA carboxylase, whereas there was no difference in hepatic fat oxidation among the groups. On the other hand, uncoupling protein 1 (UCP1) and peroxisome proliferator-activated receptor gamma coactivator alpha (PGC1) expression were significantly increased in the brown adipose tissue (BAT) of HP group. Our data demonstrated that a high Pi diet can negatively regulate lipid synthesis in the liver, and increased mRNA expression related to lipid oxidation and UCP1 in BAT, thereby preventing visceral fat accumulation. Thus, dietary Pi is a novel metabolic regulator.

(要約) Our aim in this study was to clarify the effects of respiratory-gated PET in the evaluation of lung cancer according to the (18)F-FDG uptake in an orthotopic transplantation mouse model. We created such a model, and we performed PET/CT. The mice were divided into two groups according to tumor volume: a small-tumor group (<20 mm(3)) and a large-tumor group (>20 mm(3)). We reconstructed the following conditions based on list-mode data: non-gated (3D) images and gated (4D) images, divided based on the respiratory cycle (expiration phase, stable phase, and inspiration phase). We calculated the maximum standardized uptake values (SUVmax) in each phase. We used the % difference [= (4D SUVmax - 3D SUVmax)/3D PET SUVmax × 100 (%)] to evaluate the differences in the 4D SUVmax and 3D SUVmax. The 4D SUVmax values were significantly higher than the 3D SUVmax, regardless of the tumor size. The % difference for the small tumors was greater than that for the large tumors, and it was highest in the stable phase. We conclude that the SUVmax in the stable phase under respiratory-gated PET are the most reliable. The SUVmax observed under non-gated PET are considered to be more frequently underestimated in cases involving small tumors than in those involving large tumors. In the chronologic study evaluating the time course of tumor development, the size of the tumor is small in early stage, and respiratory-gated PET is effective in reducing the underestimation of such tumors caused by respiratory motion.

(要約) Positron emission tomography-computed tomography (PET-CT) with [18F] fluorodeoxyglucose (FDG) has recently been applied for evaluating tumor response to anticancer therapy. The aim of the present study was to evaluate the utility of FDG PET-CT in monitoring non-invasively and repeatedly the inhibitory effect of cisplatin (CDDP) on an orthotopic lung cancer model. Validation of in vivo FDG uptake in human lung cancer Ma44-3 cell line in an orthotopic SCID mouse model was carried out. Next, we assessed the use of FDG PET-CT to monitor the response of orthotopic lung cancer to the anticancer effect of CDDP. SCID mice were divided into the CDDP group (7 mg/kg single dose intraperitoneally) and the control group. Tumor volume and maximal standardized uptake value (SUV max) were calculated for all mice. All mice were sacrificed for histopathologic analysis. Validation of FDG PET-CT showed that tumor volume and SUV max were significantly correlated with postmortem tumor length measured in specimens (P=0.023) and (P=0.012), respectively, and there was a significant correlation between SUV max and tumor volume (P=0.048). Response monitoring showed that significant growth inhibition by CDDP in the form of SUV max of the CDDP group was significantly lower than that of the control group on day 8 (P=0.02) and on day 13 (P=0.003). Tumor volume of the CDDP group was significantly lower than that of the control group on day 13 (P=0.03). The present study supports using FDG PET-CT in monitoring tumor progression and therapeutic response of lung cancer in an orthotopic model non‑invasively and repeatedly.

(要約) The purpose of this study was to evaluate the impact of a cyclotron on small-animal PET equipment installed directly above the cyclotron. The cyclotron equipment was HM-12, which has two targets, and the PET/CT equipment was Inveon. The equipment was installed in conformity to Japanese law and regulations. Before installation of the PET/CT equipment, the radiation dose, radio waves, and static and fluctuating magnetic fields were measured at the position where it would be placed, both when the cyclotron was in use and when it was not in use. After installation of the PET/CT, natural background and emission counts were measured at the same place under the same conditions. An increase of radiation dose was observed when the target nearest the PET equipment was used. There were no distinct effects of radio waves or static and fluctuating magnetic fields. A significant increase of emission counts, approximately 300 cpm, was observed when the nearest target was used. Though radio waves and static and fluctuating magnetic fields generated by running cyclotron had no influence, a significant increase in emission count was observed. Careful attention should be paid to this influence when very low-radioactivity PET measurements are done.
