Metabolic responses, PPAR-γ and TNF-α gene expression in type2 diabetic rats subsequent vanadyl sulfate treatment

Pak J Pharm Sci. 2024 Jan;37(1):79-84.

Abstract

Vanadyl sulfate (VS), is a component of some food supplements and experimental drugs. This study was carried out to present a novel method for induction of Type 2 diabetes in rats, then for the first time in literature, for evaluating the effect of VS on metabolic parameters and gene expression, simultaneously. 40 male wistar rats were distributed between the four groups, equally. High fat diet and fructose were used for diabetes induction. Diabetic rats treated by two different dose of VS for 12 weeks. Metabolic profiles were evaluated by commercial available kits and gene expression were assayed by real time-PCR. Compared to controls, in non-treated diabetic rats, weight, glucose, triglyceride, total cholesterol, insulin and insulin resistance were increased significantly (p-value <0.05) that indicated induction of type 2 diabetes. Further, the results showed that VS significantly reduced weight, insulin secretion, Tumor Necrosis Factor-alpha (TNF-α) genes expression, lipid profiles except HDL that we couldn't find any significant change and increased Peroxisome Proliferator-Activated Receptor- gamma (PPAR-γ) gene expression in VS-treated diabetic animals in comparison with the non-treated diabetics. Our study demonstrated that vanadyl supplementation in diabetic rats had advantageous effects on metabolic profiles and related gene expression.
