The protective effects of beta-casomorphin-7 against glucose -induced renal oxidative stress in vivo and vitro.

ABSTRACT: Oxidative stress is implicated in the pathogenesis of diabetic nephropathy. The present study aimed to investigate the effect of β-casomorphin-7 (BCM7) on the oxidative stress occurring in kidney tissue in streptozotocin (STZ)-induced diabetic rats and proximal tubular epithelial cells (NRK-52E) exposure to high glucose (HG) by using biochemical methods. There is a significant decrease in plasma insulin and a significant increase in plasma glucagon in the rats of diabetic group. Oral administration of BCM7 for 30 days to rats with STZ-induced diabetes resulted in a significant increase in serum level of insulin, and a decrease in the level of glucagon. Moreover, rats with STZ-induced diabetes had lower levels of superoxide dismutase (SOD), glutathione peroxidase (GPx) and total antioxidati
