Protective role of vildagliptin against bisphenol-A induced liver injury: targeting oxidative stress, apoptosis, and endoplasmic reticulum stress

Bisphenol-A (BPA) is an environmental pollutant that causes hepatic injury. The antioxidant activity of vildagliptin is confirmed. The present study investigated the protective effect of Vildagliptin against BPA-induced hepatotoxicity. Twenty four rats were divided randomly into 4 groups (6 rats/group): A control group, BPA group, BPA + Vildagliptin group and Vildagliptin group. All rats, except the controls were orally administered 30 mg/kg body weight BPA and/or 10 mg/kg Vildagliptin. AST, ALT, Triglycerides and albumin were measured in the serum. MDA, GPX, XBP1, Caspase 3 and BCL2 were measured in liver tissues. BPA group showed a significant decrease of albumin and GPX and a significant increase of triglycerides, AST, ALT and MDA. BPA caused up regulation of caspase3 and XBP1 while caused down regulation of BCL2. The co-administration of Vildagliptin reversed these hazards. The results of this study established the protective effect of Vildagliptin against BPA induced liver dysfunction.
