title: Effect of metformin on renal microsomal proteins, lipid peroxidation and antioxidant status in dexamethasone-induced type-2 diabetic mice.
abstract: An SDS-PAGE analysis of renal microsomal fraction of albino mice was performed to study the involvement of proteins in dexamethasone-induced type-2 diabetes mellitus (DM) and their alterations by metformin, a widely accepted oral antidiabetic drug. In addition, changes in renal lipid peroxidation (LPO), activities of superoxide dismutase (SOD) and catalase (CAT), reduced glutathione (GSH) content, as well as renal somatic index (RSI) and daily rate of water consumption were also investigated. While dexamethasone administration (1.0 mg/kg for 21 days) expressed two renal proteins (43 kDa and 63.23 kDa), in addition to the increased fasting serum levels of glucose and insulin, renal LPO, RSI and daily rate of water consumption, a parallel decrease in renal SOD, CAT and GSH was also observed. Treatment with metformin normalized these alterations including the renal proteins and LPO, confirming its efficacy in ameliorating dexamethasone-induced type-2 DM and also the association of two proteins with type-2 DM.
