Aim: To explore the relationship between the expression of PTEN gene and the expression of PPARgamma, and the human pancreatic cancer cells PANC-1 were cultured in vitro.
Methods: The effects of rosiglitazone and GW9662 on the expression of PTEN gene and PTEN protein in the human pancreatic cancer cells PANC-1 were detected by RT-PCR and immunohistochemistry respectively. In addition, the percentage of the expression of PTEN protein was analyzed by flow cytometry.
Results: The expression of PTEN gene and PTEN protein in human pancreatic cancer cells PANC-1 were all increased significantly after treated with rosiglitazone. While those were markedly reduced in GW9662 treated groups, and it has a dose-effect relationship between them.
Conclusion: The expression of PTEN gene were paralleled with the expression of PPARgammain human pancreatic cancer cells PANC-1, which may be related to its inhibitory effects on pancreatic tumor cells.
