Abstract

Objective To investigate the effect of oligoprocyanidins(OPC) on epithelial-to-mesenchymal transition (EMT) of podocytes in rats with diabetic kidney disease (DKD). Methods Thirty male SD rats were randomly divided into the control group, model group and OPC group [500 mg/(kg·d), 8 weeks]. The renal function of different groups was compared. The histological changes were observed via light and electron microscopy. The levels of EMT-related proteins were analyzed by Western blot. Results OPC could significantly reduce the levels of blood glucose, serum creatinine, urea nitrogen and urinary protein in DKD rats (P<0.05). Under an electron microscope, podocytes in the OPC group partially fused and autophagic vesicles appeared. OPC up-regulated the expression of E-cadherin but down-regulated the expression of vimentin and Twist1 in podocytes of DKD rats. Conclusions OPC can induce podocyte autophagy and reduce podocyte EMT in DKD rats.
