Abstract Obesity-dependent insulin resistance and type 2 diabetes mellitus are closely associated with decreased glucose utilization and down-regulation of hepatic glycolytic enzymes expression. Previously, we showed that DNA hypermethylation is involved in age-dependent susceptibility to hepatic insulin resistance and diabetes. However, what we cannot distinguish is whether the age-related obesity contributes to DNA hypermethylation in those natural aging rats. In the present study, we hypothesize that DNA methylation plays a crucial role in the regulation of glycolytic enzymes in the high-fat diet–induced obesity. Here, we report that DNA hypermethylation is correlated with a decline in hepatic glucokinase (Gck) and L-type pyruvate kinase (LPK) expression in high-fat diet–induced obese rats as compared with the control diet group. Down-regulation of Gck and LPK expression are reversed by the 5-aza-2′-deoxycytidine in the cell model of steatosis. These novel observations indicate that DNA methylation is involved in the development of metabolic diseases, such as obesity, insulin resistance, type 2 diabetes mellitus, and nonalcoholic steatohepatitis, suggesting that the hypermethylation level of Gck and LPK promoters may be a useful parameter for the evaluation of obesity-induced insulin resistance and fatty liver.

Introduction: The principal mechanism responsible for reducing blood glucose is through insulin-stimulated glucose transport into skeletal muscle. The transporter protein that mediates this uptake is GLUT-4. A defect in this step is associated with reduced glucose utilization in muscle and adipose tissue, as observed in insulin-resistant type-2 diabetes mellitus (T2DM) patients. This study aimed to develop an experimental T2DM model and evaluate altered glucose transporter type 4 (GLUT-4) levels as a biomarker of insulin resistance. Antidiabetic activities of Syzygium cumini hydro-ethanolic seed extracts (SCE) were also evaluated. Methods: Adult male Wistar albino rats were fed a high-fat diet for 12 weeks and dosed intraperitoneally with streptozotocin (35 mg/kg). After treatment for 21 days, all investigations were done. The homeostasis model of assessment (HOMA) was used for the calculation of insulin resistance (HOMA-IR) and beta-cell function (HOMA-B) index. Diaphragm muscle and retroperitoneal fat were collected for real-time polymerase chain reaction (RT-PCR) studies. Results: A significant increase in fasting blood glucose, HOMA-IR, and serum lipids, and a decrease in serum insulin and HOMA-B were observed in the diabetic group, effects that reversed following pioglitazone and SCE treatment. The diabetic group showed a downregulation of GLUT-4 expression in skeletal muscle while an increase was observed in adipose tissue. Conclusion: A high-fat diet and low dose streptozotocin-induced experimental T2DM model of insulin resistance was developed to screen novel insulin sensitizers. Data generated demonstrated that altered GLUT-4 levels could be used as a biomarker of insulin resistance. Antidiabetic activity of S. cumini hydro-ethanolic seed extract was also confirmed in this study.

Background: As of 2018, 2.1 billion people nearly 30% of the world’s population are either obese or overweight. Worldwide obesity has nearly tripled since 1975. It is an emerging health problem with major adverse effects on health. It is a risk factor for many chronic diseases but is best known for its role in metabolic syndrome, which can lead to type 2 diabetes mellitus as well as cardiovascular diseases. Anti-obesity drugs are available but have many side effects. Voglibose, an antidiabetic drug, is an alpha glucosidase inhibitor which shows promising results in the reduction of body weight with minimal side effects.Methods: Voglibose (7 mg/kg) was administered to rats fed with normal laboratory chows and high fat diet to see its effect on body weight, body mass index, abdominal and thoracic circumference, and lipid profile at the end of 12 weeks.Results: Administration of voglibose significantly reduced food consumption, feed efficiency and increase in body weight induced by high fat diet in rats. Rats fed on normal diet also showed reductions in the same parameters, suggesting its weight lowering effect. Reductions in the anthropometric measurements, hypolipidemic effects and glucose lowering effects were also observed.Conclusions: Voglibose prevented high fat diet-induced obesity and improvement in metabolic profile, which ultimately has systemic effects on body weight in rats. Further studies are needed to see its potential therapeutic use in obese patients with type 2 diabetes mellitus, and related complications.
