ABSTRACT
Aim To investigate the effects of rosiglitazone(ROZ)combined with cisplatin(DDP)on the growth of transplanted lung adenocarcinoma in mice and the corresponding mechanism.Methods The human lung adenocarcinoma mode was established with A549 cell in nude mice.Twenty eight female Balb/c-nu mice with lung adenocarcinoma were randomly divided into seven groups.① control group;② low-dose DDP group(1 mg?kg-1);③ high-dose DDP group(4 mg?kg-1);④ low-dose ROZ group(10 mg?kg-1);⑤ high-dose ROZ group(30 mg?kg-1);⑥ low-dose DDP plus low-dose ROZ group;⑦ low-dose DDP plus high-dose ROZ group;all the mice were sacrificed at 48 h after the last injection.Subcutaneous tumor was subjected to histological examination.Expressions of PPAR?、PTEN and pAkt in tumor tissues were detected by immunohistochemistry.Results ① In every treatment group tumor growth was suppressed significantly.Intraperitoneal injection of low and high-dose DDP,low and high-dose ROZ,low-dose DDP plus low-dose ROZ and low-dose DDP plus high-dose ROZ group resulted in a significant inhibition of the growth of A549 cells in vivo compared with that of control group(P
