■ Paper- BACKGROUND: The potassium voltage-gated channel subfamily Q member 1 (KCNQ1) gene has recently received much attention as a candidate susceptibility gene for type 2 diabetes mellitus, especially in Asian populations. We previously reported that Kcnq1 mutant mice exhibit reduced insulin secretion and hyperglycemia due to a decrease in pancreatic β-cell mass. Through in vivo and in vitro analyses, we ascertained that this mechanism is the result of the downregulation of the non-coding RNA 'Kcnq1ot1,' which is expressed in the paternal allele of the Kcnq1 gene region, causing an increase in the expression of the cell cycle inhibitor cyclin dependent kinase inhibitor 1C (Cdkn1c). It was found that decreased Kcnq1ot1 expression resulted in pancreatic β-cell failure; however, the degree of pancreatic β-cell volume reduction was not severe. METHODS: We induced obesity in Kcnq1ot1 truncation mice by feeding them a high-fat diet and evaluated pancreatic β-cell mass. RESULTS: In the present study, we reveal that CCAAT/enhancer binding protein beta (C/EBPβ), which is expressed at higher levels in pancreatic β-cells in obese individuals, further increases the expression of Cdkn1c, which is upregulated by the Kcnq1 gene mutation. We found that simultaneous Cdkn1c hypomethylation and C/EBPβ overexpression in pancreatic β-cells causes a synergistic decrease in pancreatic β-cell mass. CONCLUSION: This finding suggests that the synergistic effect of genetic factors such as Kcnq1 gene mutations and environmental factors such as obesity and overeating, which lead to increased expression of C/EBPβ, contribute to the regulation of pancreatic β-cell mass. This study is the first to show that the Kcnq1 gene is related to pancreatic β-cell mass through genetic-environment interactions.Jul. 2025, Diabetes & metabolism journal, English, International magazineScientific journal
- The condition in which the insulin secretory ability of pancreatic β-cells decreases in diabetes is extremely important, but there are currently no biomarkers that reflect pancreatic β-cell failure. Therefore, we conducted a search for biomarkers, using pancreatic β-cell-specific 3-Phosphoinositide-dependent protein kinase 1 (PDK1) knockout mice, which develop severe hyperglycemia due to a decrease in pancreatic β-cell mass without insulin resistance. The analysis was performed in young mice when metabolic abnormalities were not yet apparent. Comprehensive analysis of microRNAs contained in extracellular vesicles in the blood of these mice revealed that miR378a-3p levels were significantly lower in PDK1 knockout mice than in control mice. Furthermore, in other mouse models of diabetes, namely, db/db mice and streptozotocin-induced diabetic mice, there was an increase and decrease in miR378a-3p expression, respectively, in line with the number of β-cells. These results suggest that miR378a-3p contained in serum extracellular vesicles is a biomarker that reflects pancreatic β-cell mass before the onset of diabetes. It is hoped that miR378a-3p can be utilized to realize earlier diagnosis and treatment of diabetes.Mar. 2025, Biochemical and biophysical research communications, 750, 151367 - 151367, English, International magazineScientific journal
- In most cases, the diagnosis of diabetes in animal models is based solely on blood glucose levels. While hemoglobin A1c (HbA1c) is widely used in the diagnosis of diabetes in humans, it is rarely measured in mice in diabetes research. This is thought to be because there are no established reference values for mouse HbA1c, as well as the fact that there are very few reports on the variability and reproducibility of measurements taken using different devices. In this study, we measured HbA1c levels in diabetic mouse models using different devices based on different principles, including capillary electrophoresis, high-performance liquid chromatography, and enzymatic methods, and compared the results. A positive correlation was observed between blood glucose and HbA1c levels in all measurement methods, and high reproducibility was confirmed in the measurement of HbA1c. However, HbA1c levels measured using the enzymatic method were slightly higher than those measured using the other two methods. In addition, an examination of diabetic mice given a sodium-glucose cotransporter 2 inhibitor, which is used to treat diabetes, revealed that there was a 2-week difference in the fluctuation of mouse HbA1c levels compared with the fluctuation of blood glucose levels. Based on these results, it is thought that HbA1c can be a reliable indicator in diabetic mouse models, and it is expected to make the evaluation of abnormal glucose metabolism in mice more reliable.Jan. 2025, Experimental animals, English, Domestic magazineScientific journal

- Decreased pancreatic β-cell volume is a serious problem in patients with type 2 diabetes mellitus, and there is a need to establish appropriate treatments. Increasingly, sodium/glucose cotransporter 2 (SGLT2) inhibitors, which have a protective effect on pancreatic β-cells, are being prescribed to treat diabetes; however, the underlying mechanism is not well understood. We previously administered SGLT2 inhibitor dapagliflozin to a mouse model of type 2 diabetes and found significant changes in gene expression in the early-treated group, which led us to hypothesize that epigenetic regulation was a possible mechanism of these changes. Therefore, we performed comprehensive DNA methylation analysis by methylated DNA immunoprecipitation using isolated pancreatic islets after dapagliflozin administration to diabetic model mice. As a result, we identified 31 genes with changes in expression due to DNA methylation changes. Upon immunostaining, cystic fibrosis transmembrane conductance regulator and cadherin 24 were found to be upregulated in islets in the dapagliflozin-treated group. These molecules may contribute to the maintenance of islet morphology and insulin secretory capacity, suggesting that SGLT2 inhibitors' protective effect on pancreatic β-cells is accompanied by DNA methylation changes, and that the effect is long-term and not temporary. In future diabetes care, SGLT2 inhibitors may be expected to have positive therapeutic effects, including pancreatic β-cell protection.Sep. 2024, Biochemical and biophysical research communications, 725, 150254 - 150254, English, International magazineScientific journal
- Liver fibrosis is associated with non-alcoholic fatty liver disease (NAFLD), and one of the most important risk factors for NAFLD is type 2 diabetes (T2DM). The Fibrosis-4 (FIB-4) index, a noninvasive liver fibrosis score, has been found to be useful for estimating liver fibrosis. Because individuals with non-obese NAFLD were recently reported to be metabolically unhealthy and have a higher risk of T2DM than individuals with obese NAFLD, we hypothesized that the clinical factors related to a high FIB-4 index would differ between non-obese and obese Japanese T2DM patients. Accordingly, we examined the relationship between clinical factors and the FIB-4 index in non-obese and obese Japanese patients with T2DM. We divided 265 patients into two groups by BMI level - a non-obese group (n = 149) and an obese group (n = 116) - and examined the correlation between the FIB-4 index and clinical parameters. Single regression analysis revealed that a high FIB-4 index was correlated with a reduction in the estimated glomerular filtration rate and hypertension in the non-obese group. Importantly, multiple regression analysis showed that only a reduction in the estimated glomerular filtration rate was significantly associated with a high FIB-4 index in the non-obese group. These results demonstrated that non-obese T2DM patients with a high FIB-4 index might be at risk of kidney dysfunction. Our findings may enable the more appropriate treatment of T2DM patients based on BMI level.Apr. 2024, The Kobe journal of medical sciences, 70(1) (1), E39-E45, English, Domestic magazineScientific journal

- Patients with eczema with a systemic metal allergy, such as nickel (Ni), cobalt (Co), chromium (Cr), and tin (Sn), should pay attention to symptomatic exacerbation by excessive metal intake in food. However, dietary intervention for systemic metal allergy can be difficult. In this study, we evaluated the effect of dietary intervention by a registered dietitian on clinical symptoms in patients with a systemic metal allergy. Forty-four patients with cutaneous symptoms who were diagnosed with a metal allergy were randomly assigned to the dietary intervention group (DI group, n = 29) by a registered dietitian or the control group (C group, n = 15). The DI group was individually instructed by a registered dietitian how to implement a metal-restricted diet and then evaluated 1 month later. Dermatologists treated skin lesions of patients in both groups. Skin symptoms assessed by the Severity Scoring of Atopic Dermatitis (SCORAD) index, blood tests, and urinary metal excretion were evaluated. The DI group showed decreased Ni, Co, Cr, and Sn intake (all P ≤ 0.05), and an improved total SCORAD score, eczema area, erythema, edema/papulation, oozing/crust, excoriation, lichenization and dryness after 1 month of intervention compared with before the intervention (all P ≤ 0.05). However, the C group showed decreased Ni and Sn intake and an improved oozing/crust score (all P < 0.05). It showed the effective reduction of dietary metal intake controls dermatitis due to a metal allergy. In conclusion, dietary intervention by a registered dietitian is effective in improving skin symptoms with a reduction in metal intake.Jan. 2024, The Kobe journal of medical sciences, 69(4) (4), E129-E143, English, Domestic magazineScientific journal
- Nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes are interacting comorbidities of obesity, and increased hepatic de novo lipogenesis (DNL), driven by hyperinsulinemia and carbohydrate overload, contributes to their pathogenesis. Fatty acid synthase (FASN), a key enzyme of hepatic DNL, is upregulated in association with insulin resistance. However, the therapeutic potential of targeting FASN in hepatocytes for obesity-associated metabolic diseases is unknown. Here, we show that hepatic FASN deficiency differentially affects NAFLD and diabetes depending on the etiology of obesity. Hepatocyte-specific ablation of FASN ameliorated NAFLD and diabetes in melanocortin 4 receptor-deficient mice but not in mice with diet-induced obesity. In leptin-deficient mice, FASN ablation alleviated hepatic steatosis and improved glucose tolerance but exacerbated fed hyperglycemia and liver dysfunction. The beneficial effects of hepatic FASN deficiency on NAFLD and glucose metabolism were associated with suppression of DNL and attenuation of gluconeogenesis and fatty acid oxidation, respectively. The exacerbation of fed hyperglycemia by FASN ablation in leptin-deficient mice appeared attributable to impairment of hepatic glucose uptake triggered by glycogen accumulation and citrate-mediated inhibition of glycolysis. Further investigation of the therapeutic potential of hepatic FASN inhibition for NAFLD and diabetes in humans should thus consider the etiology of obesity.Sep. 2023, JCI insight, 8(17) (17), English, International magazineScientific journal

- Chlorogenic Acid and Caffeine in Coffee Restore Insulin Signaling in Pancreatic Beta Cells.The incidence of type 2 diabetes is reported to be lower in frequent coffee drinkers than in non-coffee drinkers. To elucidate the mechanism by which coffee prevents the onset of type 2 diabetes, we analyzed how caffeine and chlorogenic acid, which are components of coffee, alter insulin signaling in MIN6 cells, a mouse pancreatic Β cell line. The results showed that caffeine improved insulin signaling under endoplasmic reticulum stress, and chlorogenic acid protected pancreatic Β cells by enhancing the expression of insulin receptor substrate 2 via cAMP response element-binding protein and promoting insulin signaling downstream of insulin receptor substrate 2. In addition, chlorogenic acid was a potent antioxidant for the protection of pancreatic Β cells. Furthermore, in vivo and in vitro analyses revealed that the pancreatic Β cell-protective effect of chlorogenic acid was mediated by the alleviation of endoplasmic reticulum stress. The results suggest that these components of coffee have the potential to reduce the pathogenesis of type 2 diabetes and improve pancreatic Β cell insufficiency.Mar. 2023, The Kobe journal of medical sciences, 69(1) (1), E1-E8, English, Domestic magazineScientific journal
- Eif2ak4, a susceptibility gene for type 2 diabetes, encodes GCN2, a molecule activated by amino acid deficiency. Mutations or deletions in GCN2 in pancreatic β-cells increase mTORC1 activity by decreasing Sestrin2 expression in a TSC2-independent manner. In this study, we searched for molecules downstream of GCN2 that suppress mTORC1 activity in a TSC2-dependent manner. To do so, we used a pull-down assay to identify molecules that competitively inhibit the binding of the T1462 phosphorylation site of TSC2 to 14-3-3. l-asparaginase was identified. Although l-asparaginase is frequently used as an anticancer drug for acute lymphoblastic leukemia, little is known about endogenous l-asparaginase. l-Asparaginase, which is expressed downstream of GCN2, was found to bind 14-3-3 and thereby to inhibit its binding to the T1462 phosphorylation site of TSC2 and contribute to TSC2 activation and mTORC1 inactivation upon TSC2 dephosphorylation. Further investigation of the regulation of mTORC1 activity in pancreatic β-cells by l-asparaginase should help to elucidate the mechanism of diabetes and insulin secretion failure during anticancer drug use.Feb. 2023, Biochemical and biophysical research communications, 652, 121 - 130, English, International magazineScientific journal
- Pancreatic β-cells are the only type of cells that can control glycemic levels via insulin secretion. Thus, to explore the mechanisms underlying pancreatic β-cell failure, many reports have clarified the roles of important molecules, such as the mechanistic target of rapamycin (mTOR), which is a central regulator of metabolic and nutrient cues. Studies have uncovered the roles of mTOR in the function of β-cells and the progression of diabetes, and they suggest that mTOR has both positive and negative effects on pancreatic β-cells in the development of diabetes.Apr. 2022, Biomolecules, 12(5) (5), English, International magazineScientific journal

- The main pathogenic mechanism of diabetes consists of an increase in insulin resistance and a decrease in insulin secretion from pancreatic β-cells. The number of diabetic patients has been increasing dramatically worldwide, especially in Asian people whose capacity for insulin secretion is inherently lower than that of other ethnic populations. Causally, changes of environmental factors in addition to intrinsic genetic factors have been considered to have an influence on the increased prevalence of diabetes. Particular focus has been placed on "gene-environment interactions" in the development of a reduced pancreatic β-cell mass, as well as type 1 and type 2 diabetes mellitus. Changes in the intrauterine environment, such as intrauterine growth restriction, contribute to alterations of gene expression in pancreatic β-cells, ultimately resulting in the development of pancreatic β-cell failure and diabetes. As a molecular mechanism underlying the effect of the intrauterine environment, epigenetic modifications have been widely investigated. The association of diabetes susceptibility genes or dietary habits with gene-environment interactions has been reported. In this review, we provide an overview of the role of gene-environment interactions in pancreatic β-cell failure as revealed by previous reports and data from experiments.Jan. 2022, Diabetes & metabolism journal, 46(1) (1), 38 - 48, English, International magazineScientific journal
- BACKGROUND: L-amino acids are the predominant forms of organic molecules on the planet, but recent studies have revealed that various foods contain D-amino acids, the enantiomers of L-amino acids. Though diet plays important roles in both the development and progression of inflammatory bowel disease (IBD), to our best knowledge, there has been no report on any potential interactions between D-amino acids and IBD. In this report, we aim to assess the effects of D-serine in a murine model of IBD. MATERIALS AND METHODS: To induce chronic colitis, naïve CD4 T cells (CD4+ CD62+ CD44low) from wild-type mice were adoptively transferred into Rag2-/- mice, after or before the mice were orally administered with D-serine. In vitro proliferation assays were performed to assess naïve CD4 T cell activation under the Th-skewing conditions in the presence of D-serine. RESULTS: Mice treated with D-serine prior to the induction of colitis exhibited a reduction in T-cell infiltration into the lamina propria and colonic inflammation that were not seen in mice fed with water alone or L-serine. Moreover, D-serine suppressed the progression of chronic colitis when administered after the disease induction. Under in vitro conditions, D-serine suppressed the proliferation of activated CD4 T cells and limited their ability to differentiate to Th1 and Th17 cells. CONCLUSION: Our results suggest that D-serine not only can prevent, but also has efficacious effects as a treatment for IBD.Aug. 2021, Journal of gastroenterology, 56(8) (8), 732 - 745, English, Domestic magazineScientific journal
- AIMS/INTRODUCTION: Glutamine is the most abundant amino acid in the circulation. In this study, we investigated cell signaling in the amplification of insulin secretion by glutamine. MATERIALS AND METHODS: Clonal pancreatic β-cells MIN6-K8, wild-type B6 mouse islets, glutamate dehydrogenase (GDH) knockout clonal β-cells (Glud1KOβCL), and glutamate-oxaloacetate transaminase 1 (GOT1) knockout clonal β-cells (Got1KOβCL) were studied. Insulin secretion from these cells and islets was examined under various conditions, and intracellular glutamine metabolism was assessed by metabolic flux analysis. Intracellular Ca2+ concentration ([Ca2+ ]i ) was also measured. RESULTS: Glutamine dose-dependently amplified insulin secretion in the presence of high glucose in both MIN6-K8 cells and Glud1KOβCL. Inhibition of glutaminases, the enzymes that convert glutamine to glutamate, dramatically reduced the glutamine-amplifying effect on insulin secretion. A substantial amount of glutamate was produced from glutamine through direct conversion by glutaminases. Glutamine also increased [Ca2+ ]i at high glucose, which was abolished by inhibition of glutaminases. Glutamic acid dimethylester (dm-Glu), a membrane permeable glutamate precursor that is converted to glutamate in cells, increased [Ca2+ ]i as well as induced insulin secretion at high glucose. These effects of glutamine and dm-Glu were dependent on calcium influx. Glutamine also induced insulin secretion in clonal β-cells MIN6-m14, which otherwise exhibit no insulin secretory response to glucose. CONCLUSIONS: Glutamate converted from glutamine is an essential mediator that enhances calcium signaling in the glutamine-amplifying effect on insulin secretion. Our data also suggest that glutamine exerts a permissive effect on glucose-induced insulin secretion.Jan. 2021, Journal of diabetes investigation, 12(6) (6), 920 - 930, English, Domestic magazineScientific journal
- OBJECTIVE: The purpose of this study is to investigate the effect of an intervention combining exercise and cognitive activity on cognitive function in healthy older adults. METHODS: This pilot randomized controlled trial recruited 33 eligible, healthy communitydwelling older adults (mean age, 77.1 years old; women, 51.5%), who were divided into intervention and waitlist control groups. The intervention group was engaged weekly in a group activity comprising exercise and discussions of homework, which included reading aloud, simple arithmetic, and simple activities, like spotting differences, for cognitive stimulation. They were also required to complete cognitive activity homework twice a week. The waitlist control group received no intervention. The main outcomes were cognitive function assessed using the Mini-Mental State Examination, delayed recall score on the Logical Memory IIA of the Wechsler Memory Scale Revised, Trail Making Test, and digit symbol substitution test. RESULTS: According to the results, Mini-Mental State Examination scores were maintained in the intervention group but declined in the control group [Mean change in outcomes in control group (95% confidence interval): -1.68 (-2.89 to -0.48)]. Additional mean change in outcomes in intervention group were found [1.68 (0.02 to 3.35)]. CONCLUSIONS: Interventions combining exercise and cognitive activity can be helpful for preserving cognitive function in healthy older adults.2021, Physical therapy research, 24(2) (2), 112 - 119, English, Domestic magazine[Refereed]Scientific journal

- EIF2AK4, which encodes the amino acid deficiency-sensing protein GCN2, has been implicated as a susceptibility gene for type 2 diabetes in the Japanese population. However, the mechanism by which GCN2 affects glucose homeostasis is unclear. Here, we show that insulin secretion is reduced in individuals harboring the risk allele of EIF2AK4 and that maintenance of GCN2-deficient mice on a high-fat diet results in a loss of pancreatic β cell mass. Our data suggest that GCN2 senses amino acid deficiency in β cells and limits signaling by mechanistic target of rapamycin complex 1 to prevent β cell failure during the consumption of a high-fat diet.May 2020, JCI insight, 5(9) (9), English, International magazine[Refereed]Scientific journal

- OBJECTIVE: To evaluate the usefulness of en face slab optical coherence tomography (OCT) imaging for monitoring diabetic retinal neurodegeneration with supporting animal experimental data. RESEARCH DESIGN AND METHODS: We retrospectively examined 72 diabetic eyes over 3 years using Cirrus-HD OCT. Two-dimensional en face slab OCT images of the innermost retina were reconstructed and graded according to the ratio of dark area to total area, and relative red, green, and blue color area ratios were calculated and used as indexes for each en face slab OCT image. Values from en face OCT images were used for statistical analyses. To obtain insight into the pathogenesis of diabetic retinal neurodegeneration, we used the InsPr-Cre;Pdk1flox/flox diabetic mouse model. RESULTS: Both OCT grade and relative red color area ratio significantly increased with the advancing stage of diabetic retinopathy (p=0.018 and 0.006, respectively). After a mean follow-up period of 4.6 years, the trend was unchanged in the analyses of 42 untreated eyes (p<0.001 and 0.001, respectively). Visual acuity showed a weak but significant negative correlation with the red color ratio on en face slab OCT images, but central retinal thickness did not exhibit a clinically meaningful correlation with values obtained from en face slab OCT images. Immunohistochemical analyses of InsPr-Cre;Pdk1flox/flox diabetic mice demonstrated the loss of ganglion axon bundles and thinning of laminin without apparent retinal vascular change at the age of 20 weeks. CONCLUSIONS: En face slab OCT imaging would be a novel useful modality for the assessment of diabetic retinal neurodegeneration as it could detect subtle optical changes occurring in the innermost retina in diabetic eyes. Our animal experimental data suggest that dark areas observed on en face slab OCT images might be the impairment of the extracellular matrix as well as neurons.Mar. 2020, BMJ open diabetes research & care, 8(1) (1), English, International magazine[Refereed]Scientific journal

- AIMS/INTRODUCTION: Mean platelet volume (MPV) is a widely used biological marker of platelet function and activity. Increased MPV is associated with accelerated thrombopoiesis and an elevated risk of cardiovascular disease. However, it is not known whether higher MPV is related to the pathogenesis of type 2 diabetes and diabetic macrovascular complications in Japanese patients. Therefore, we analyzed MPV and its correlation with atherosclerosis in Japanese patients with type 2 diabetes and those who had prediabetes. MATERIALS AND METHODS: We divided the patients into three groups: normoglycemic patients (n = 56), prediabetes patients (n = 44) and type 2 diabetes patients group, (n = 115). We measured platelet parameters and evaluated arterial stiffness in the three groups. RESULTS: Significantly higher MPV was found in the type 2 diabetes mellitus and prediabetes patients compared with normoglycemic patients. MPV was significantly correlated with fasting blood glucose and glycated hemoglobin levels. Multiple linear regression analysis showed that MPV was positively correlated with HbA1c, even after adjustment for confounding factors. In the evaluation of arterial stiffness by measuring the cardio-ankle vascular index and maximum intima-media thickness, MPV showed a positive correlation with these parameters. CONCLUSIONS: These findings suggest that MPV was significantly increased in the early stage of type 2 diabetes. We showed positive correlations between MPV and HbA1c levels, and between MPV and arterial stiffness in Japanese patients with type 2 diabetes.Dec. 2019, Journal of diabetes investigation, English, Domestic magazine[Refereed]

- Constitutive activation of Rac1 in pancreatic β cells facilitates F-actin depolymerization but exerts no influence on the increase of pancreatic β cell mass and facilitation of insulin secretion.Insulin secretion from pancreatic β cells has an important role in the onset of type 2 diabetes. Insulin secretion from pancreatic β cells is regulated by pancreatic β cell mass and their insulin secretory function. By using pancreatic β cell-specific Rac1-knockout mice, we recently showed that Rac1 deletion, even with no reduction in pancreatic β cell mass, inhibits F-actin depolymerization, which causes insulin secretion to decline. However, the effect of Rac1 deficiency on the growth and apoptosis of pancreatic β cells was not clarified. Further, the effect of constitutive Rac1 activation on the secretion of insulin from pancreatic β cells has not been studied. Here, we used pancreatic islets isolated from pancreatic β cell-specific Rac1-knockout mice to evaluate the growth and apoptosis of pancreatic β cells. We found that Rac1 deficiency does not influence the growth or apoptosis of pancreatic β cells. Further, when a constitutively activated form of Rac1 (G12V) is expressed, F-actin depolymerization was increased in the pancreatic β cell lines, which had no effect on pancreatic β cell growth or glucose-stimulated insulin secretion. These findings indicate that excessive Rac1 expression or activation in pancreatic β cells facilitates F-actin depolymerization, but has no effect on insulin secretion.May 2013, The Kobe journal of medical sciences, 59(3) (3), E72-80 - 80, English, Domestic magazine[Refereed]Scientific journal

- The development of type 2 diabetes is accompanied by a progressive decline in β-cell mass and function. Vildagliptin, a dipeptidyl peptidase 4 inhibitor, is representative of a new class of antidiabetic agents that act through increasing the expression of glucagon-like peptide-1. The protective effect of this agent on β cells was studied in diabetic mice. Diabetic pancreatic β cell-specific C/EBPB transgenic (TG) mice exhibit decreased β-cell mass associated with increased apoptosis, decreased proliferation, and aggravated endoplasmic reticulum (ER) stress. Vildagliptin was orally administered to the TG mice for a period of 24 weeks, and the protective effects of this agent on β cells were examined, along with the potential molecular mechanism of protection. Vildagliptin ameliorated hyperglycemia in TG mice by increasing the serum concentration of insulin and decreasing the serum concentration of glucagon. This agent also markedly increased β-cell mass, improved aggravated ER stress, and restored attenuated insulin/IGF1 signaling. A decrease in pancreatic and duodenal homeobox 1 expression was also observed in β cells isolated from our mouse model, but this was also restored by vildagliptin treatment. The expression of C/EBPB protein, but not mRNA, was unexpectedly downregulated in vildagliptin-treated TG mice and in exenatide-treated MIN6 cells. Activation of the GLP1 pathway induced proteasome-dependent C/EBPB degradation in β cells as the proteasome inhibitor MG132 restored the downregulation of C/EBPB protein by exenatide. Vildagliptin elicits protective effects on pancreatic β cells, possibly through C/EBPB degradation, and has potential for preventing the progression of type 2 diabetes.Oct. 2012, Journal of molecular endocrinology, 49(2) (2), 125 - 35, English, International magazine[Refereed]Scientific journal

- Measurement of ionized calcium is more important than measurement of total calcium in serum samples. In the present study, equations were derived from complexation and acid dissociation equilibrium equations, and were used to determine the concentration of ionized calcium from the observed serum concentrations of total calcium, albumin, total protein, and inorganic phosphate. The ionized calcium concentration was calculated in 67 serum samples from healthy subjects and 34 outpatients previously identified as having abnormal serum calcium levels. The correlation coefficient between our method (y) and the calcium-ion-selective electrode method (x) was 0.953 and the linear regression equation was y = 0.97x at pH 7.4 with a factor of α = 0.21, which was based on the differences between the concentrations of calcium phosphorus compounds obtained by the electrode method and by calculation. The developed calculation is as useful and accurate as the electrode method, and therefore extremely useful for clinical diagnoses.2012, Analytical chemistry insights, 7, 23 - 30, English, International magazine[Refereed]Scientific journal

- We studied the relationship between dietary self-management behavior and actual energy intake by Type 2 diabetic individuals based on clinical backgrounds and profiles of gender, age, HbA1c, body mass index (BMI), and waist size. Subjects were 99 men and 77 women. Using data from the dietary self-management behavior questionnaire (DSBQ) and semiquantitative food frequency questionnaire, which lists 122 dishes, we initially divided clinical profiles into two groups. We then assessed the rank correlation coefficient between DSBQ factors and dietary intake using Student's t-test and Spearman's technique. We noted three trends: (1) Men aged <60 showed a noticeably low frequency of behavior such as “Device to enhance satisfaction during meals,” “Device to reduce the use of high-calorie seasoning,” and “Device to eat tasty food while maintaining nutritional balance,” Similarly, those with a BMI of >25 and a waist of >85 cm demonstrated a noticeably low frequency of behavior such as “Device to avoid excessive food intake,” “Device to enhance satisfaction during meals,” and “Device to eat tasty food while maintaining nutritional balance,” consequently reflected in increased dietary intake. (2) Women with HbA1c <7.0% showed a noticeably high frequency of behavior such as “Device to reduce the amount of cooking salt,” consequently reflected in decreased dietary intake. Women with a BMI of >25 and a waist of >90 cm showed a high frequency of “Behavior that each allows one's own value system to take priority even if it means eating inappropriate food” in behavior to cope with factors interfering with dietary regimens, consequently reflected in increased dietary intake. Results suggest that it is important for the sake of good care to point out each own characteristics of self-management behavior using the DSBQ.THE JAPAN DIABETES SOCIETY, 2008, Journal of the Japan Diabetes Society, 51(2) (2), 125 - 138, Japanese[Refereed]

- In order to clarify the interaction of hormones which exert various effects on the exocrine pancreas, we investigated the effect of cholecystokinin (CCK) and secretin on subsequent insulin binding to pancreatic acini and cultured AR42J cells derived from azaserine-induced acinar cell carcinoma of the pancreas. CCK at concentrations of 100pM-lOnM inhibited subsequent 125I-insulin binding to pancreatic acini. 12-O-tetradecanoylphorbol 13-acetate (TPA) inhibited 125I-insulin binding whereas A23187 had little effect, suggesting that the in-hibitory effect of CCK is mediated by protein kinase C. On the other hand, 100pM-10nM secretin had no effect on subsequent 125I-insulin binding to pancreatic acini, although higher concentrations of forskolin and 8 bromoadenosine 3', 5'-cyclic monophosphate inhibited 125I-insulin binding. In addition, secretin exerted no potentiating effect on the inhibitory effect of CCK on 125I-insulin binding to pancreatic acini. Based on these results, we further investigated the effect of CCK and TPA on subsequent 125I-insulin binding to AR42J cells. In this carcinoma cell line, inhibitory effect of CCK and TPA on insulin binding was completely abolished. The present results suggest, therefore, that hormonal interaction may play an important role in the regulation of exocrine pancreatic function including acinar cell growth.The Japanese Society of Gastroenterology, 1993, Nippon Shokakibyo Gakkai Zasshi, 90(3) (3), 685 - 692, Japanese

- 日本学術振興会, 科学研究費助成事業, 基盤研究(C), 神戸大学, 01 Apr. 2021 - 31 Mar. 2024膵β細胞におけるインスリンシグナルが可塑性に及ぼす影響の解明代表者が独自に作成した膵β細胞特異的Tsc2ノックアウトマウスは、若齢期において膵β細胞量増大、高インスリン血症、低血糖を呈するが、45週齢前後から徐々に血糖上昇を示すことが明らかとなった。その際の膵β細胞量は若齢期と比べて有意に減少しており、またインスリン染色をしたところ膵島内のインスリン陽性細胞が不均一となっていた。既報では、膵β細胞量減少の一機序として脱分化が近年注目されており、本マウスにおいても脱分化が起こっていることが示唆された。しかしながら、膵α細胞量増大は認められず、またインスリン・グルカゴン・PP・ソマトスタチン陰性クロモグラニンA陽性細胞が認められたことから、内分泌ホルモン陰性細胞が膵島内に存在することが明らかとなった。そこで、アミラーゼ染色を行ったところ、膵島内にアミラーゼ陽性細胞が多数認められた。アミラーゼ発現が膵内分泌細胞の脱分化であることを確認するために、若齢期においてPtf1a発現を免疫染色で確認したところ、Ptf1a、クロモグラニンA共発現細胞の存在が確認された。さらにこれらの結果を確認するために、YFPマウスと交配し、Lineage tracingを行ったところ、YFP陽性Ptf1a陽性細胞がTsc2ノックアウトマウスの膵島内においてのみ確認された。また、遺伝子発現変化を確認すべくRNA-seqをしたところ、Tsc2ノックアウトマウスの10週齢ではPdx1やMafA発現が低下しており、Aldh1a3発現が増加していた。これらの結果より、若齢期から脱分化が始まっている可能性が示唆された。
- 日本学術振興会, 科学研究費助成事業, 基盤研究(C), 神戸大学, 01 Apr. 2020 - 31 Mar. 2023日本人2型糖尿病感受性遺伝子GCN2が膵β細胞機能に及ぼす影響に関する検討2型糖尿病の発症・進展には、膵β細胞の質的異常のみならず、膵β細胞量調節機構の異常の関与が明らかとなっている。ヒト被験者における2型糖尿病に関連するGCN2のSNP多型と代謝パラメータとの関係を評価し、リスク対立遺伝子を有する被験者では75gOGTT試験ならびにインスリンクランプ試験にてインスリン分泌が減少していることを見出した。高脂肪食負荷全身性GCN2ノックアウトマウスが耐糖能異常および膵β細胞量減少をきたすこと、およびβ細胞特異的GCN2ノックアウトマウスは高脂肪食負荷後の耐糖能異常および膵β細胞量減少を認めることを既に確認している。GCN2の機能不全が膵β細胞のインスリン分泌能に影響を与えるメカニズムを解明することが本研究の目的である。 当該年度高脂肪食負荷全身性GCN2ノックアウトマウスの膵島およびGCN2ノックダウンINS-1細胞においてSestrin2の発現が低下していることが明らかとなった。このSestrin2がmTORC1活性をネガティブコントロールしていることが培養細胞において確認済である。我々は、mTORC1活性調節に重要なTSC2/14-3-3結合に干渉しうる分子を同定するため、アミノ酸欠損下で培養したコントロールINS-1細胞とGCN2ノックダウンINS-1細胞においてプロテオーム解析を行った。4つの候補分子の中から、L-asparaginaseが糖負荷によりMIN-6細胞および高脂肪食負荷マウスにおいて発現が上昇することを見出した。ここまでの結果において、高脂肪食負荷において、インスリン需要が増大し、膵β細胞におけるインスリン合成が亢進しアミノ酸濃度が減少することにより、GCN2のリン酸化が惹起され、mTORC1活性の調整がSestrin2やL-asparaginaseを介して行われる新たなメカニズムの存在が示唆された。

In the fasted state, hepatic KAT2A formed a signalling module with transcriptional coregulator CITED2 and PKA promoted transcription of fasting response genes, and thereby adapted to fasting. Mechanistically, KAT2A was phosphorylated by PKA within the module, switched its substrate from transcriptional coactivator PGC-1α to histone H3, and thereby promoted activation of this coactivator and epigenomic changes in the promoter, resulting in activation of such gene transcription. These results suggest that KAT2A is a cAMP-responsible acetyltransferase that is critical to integrate fasting metabolic response in hepatocytes.

These mice also revealed signals used to communicate between organs. For example, we found insulin action in the brain inhibited hepatic glucose production via the nervous system. Thus, homeostasis in a whole body is regulated ingeniously by signals used to communicate within organs and between organs.

This turned out to be one of the most important genetic factors in multiple ethnic groups. We also examined other genetic factors for diabetes and found that risk allele frequencies of the SNPs are variable among populations. Furthermore, we reported that the prediction power of all the susceptibility SNPs combined is not sufficient, indicating the existence of unknown genetic factors. We also reported novel diabetes-related genes by candidate gene and candidate region approaches.
