摘    要:目的:探讨细胞周期蛋白依赖激酶(CDK)抑制剂Roscovitine(Ros)诱导非小细胞肺癌(NSCLC)A549细胞凋亡及其作用机制。方法:以不同浓度Ros(10μM、20μM、40μM)处理细胞24h,采用Annexin V-PI染色以流式细胞仪检测细胞凋亡,Westernblot法检测胞浆中和线粒体促凋亡蛋白Bax和Bad的表达,流式细胞仪检测线粒体膜电位(MMP)变化。结果:Ros以剂量依赖的方式诱导A549细胞凋亡,同时Bad和Bax在胞浆的含量随着Ros剂量的增加而减少,而在线粒体中却出现相反的结果,线粒体膜电位随Ros剂量的增大而降低。结论:Ros可通过促进Bax和Bad由胞浆向线粒体易位,诱导NSCLC A549细胞由线粒体途径发生凋亡。

关 键 词:Roscovitine  肺癌细胞  细胞凋亡  Bax  Bad

Abstract:Objective:To investigate the effect of cyclin dependent kinase inhibitor roscovitine(Ros)-induced apoptosis on non-small cell lung cancer A549 cells and its mechanisms.Methods:A549 cells were exposed to varying concentrations of Ros for 24h.Apoptosis was detected with Annexin V-PI staining by flow cytometry.The expression of pro-apoptotic protein Bax and Bad in cytoplasm and mitochondria was detected by western blot.The changes of mitochondrial membrane potential(MMP) were analyzed by flow cytometry.Results...
Keywords:Roscovitine  Non-small cell lung cancer  Apoptosis  Bax  Bad
