Extract

Cyclosporine-A (CsA) is the widely used immunosuppressant drug in renal transplantation. However, the effects of cyclosporine-A are limited by a significant nephrotoxicity. The mechanisms of CsA-induced allograft nephropathy are remaining controversial. Recent study indicated that cellular apoptosis may contribute to the cyclosporine A-mediated cytotoxic action. To date, regarding the effects of cyclosporine A on renal cell apoptosis-related gene expression remain poorly defined. p53 is an important gene in control of renal cell growth and death. Transforming growth factor-beta (TGF-beta) is a multifunctional cytokine that has anti-proliferative as well as fibrogenic properties.

We hypothesized that cyclosporine-A may increase p53 and TGF-β expression in renal tubular cells. These actions of cyclosporine-A may contribute to the cellular apoptosis, fibrosis and CsA-induced nephrotoxicity. Therefore, current study was designed to determine the effects of cyclosporine-A on the p53 and TGF-βl protein expression by immunohistochemical staining (IHCS) in cultured human tubular cells.
