Protein kinase C inhibitor prevents renal apoptotic and fibrotic changes in response to partial ureteric obstruction

• Renal tubular apoptosis and interstitial fibrosis after obstructive nephropathy are associated with PKCα and PKCβ activation. • The PKCI, chelerythrine, is capable of decreasing PKC expression and translocation in the renal cortex, suggesting that this inhibitor may have therapeutic potential in the protection of renal function in the first few weeks after PUUO surgery.
