Effect of rapamycin on proliferation, invasion, adhesion, apoptosis and autophagy of human lung adenocarcinoma A549 and resistant A549/DDP cells treated with cis-diamminedichloroplatinum
摘要
Abstract
[ ABSTRACT] AIM:To study the effect of rapamycin ( Rap) on the proliferation, invasion, adhesion, apoptosis and autophagy of human adenocarcinoma A549 and resistant A549/DDP cells treated with cis-diamminedichloroplatinum ( DDP) .METHODS: Human adenocarcinoma A549 and resistant A549/DDP cell lines were cultured.The inhibitory effects of Rap alone or combined with DDP on A549 and resistant A549/DDP cells were detected by MTT assay.The in vitro invasion abilities of the 2 cell lines treated with Rap alone or combined with DDP were detected by Transwell methods. The in vitro adhesion abilities of the 2 cell lines treated with Rap alone or combined with DDP were detected by adhesion experiments.The apoptosis of A549 and resistant A549/DDP cells induced by Rap alone or combined with DDP was ana-lyzed by flow cytometry.The cell autophagy marker proteins beclin-1 and LC3 in A549 and resistant A549/DDP cells trea-ted with Rap alone or combined with DDP were detected by Western blotting.RESULTS:Compared with Rap or DDP a-lone group, the combination of Rap and DDP significantly inhibited the proliferation, invasion and adhesion of A549 and resistant A549/DDP cells in vitro, and promoted the cell apoptosis and autophagy marker proteins beclin-1 and LC3 expres-sion ( all P<0.05) .CONCLUSION:Rap enhances the effect of DDP through promoting the cell autophagy, thereby in-hibiting the proliferation, invasion and adhesion of A549 and resistant A549/DDP cells and inducing the cell apoptosis with a synergistic effect.关键词
