摘要：

Agonists of peroxisome proliferator-activated receptor gamma (PPAR gamma) have been examined as chemopreventive and chemotherapeutic agents. The aim was to investigate the cytotoxicity of troglitazone (TGZ) and its mechanisms in terms of PPAR gamma dependency and the p38 mitogen-activated protein kinase (MAPK) pathway in three human renal cell carcinoma (RCC) cell lines, 786-O, Caki-2 and ACHN cells. TGZ induced apoptosis and exerted cytotoxicity in a PPAR gamma-independent manner. We demonstrated that TGZ activated the p38 MAPK pathway and was involved in the cytotoxicity of TGZ. It was also revealed that TGZ induced G(2)/M cell cycle arrest through activation of p38 MAPK. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
