Type 2 diabetes (T2D) is characterized by insufficient insulin secretion by the pancreatic beta cells and insulin resistance in liver, skeletal muscle, and white adipose tissue. Adipose tissue plays a major role in glucose homeostasis and lipid metabolism. Dietary antioxidants such as resveratrol and mangiferin may offer some protection against the early stage of diabetes mellitus. Therefore, an attempt has been made to investigate the effects of resveratrol and mangiferin on biochemical parameters and molecular mechanism of PPARγ and FALDH gene expression in adipose tissue of streptozotocin- (STZ-) nicotinamide- (NA-) induced diabetic rats. Albino Wister rats were randomly divided into five groups: control rats (Group 1), diabetic control rats (Group 2), diabetic rats given resveratrol (40 mg/kg body weight per day; Group 3), diabetic rats given mangiferin (40 mg/kg body weight per day; Group 4), diabetic rats given glibenclamide (0.6 mg/kg body weight per day; Group 5). Serum biochemical parameters-total cholesterol (TC), total triglyceride (TG), low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, glycosylated hemoglobin (HbA1c), urea, and uric acid were analyzed. We found that the oral administration of resveratrol and mangiferin to STZ-NA-induced diabetic rats for 30 days showed the significant protective effect on all the biochemical parameters. A significant reduction in blood glucose and HbA1c levels was observed in rats treated with 40 mg/kg body weight per day of resveratrol or mangiferin. Moreover, both these antioxidants showed significant enhancement of PPARγ and FALDH gene expression in rat adipose tissue compared to control rats.
