摘要: 目的 研究熊果酸作用胃癌细胞BGC-823后丝切蛋白cofilin-1表达的变化。方法 熊果酸作用于细胞BGC-823,双向电泳结合质谱检测胞浆内cofilin-1的表达,免疫印迹检测cofilin-1蛋白和细胞色素c的表达。结果 胞质内cofilin-1蛋白表达降低(p<0.01),而线粒体表达却明显升高(p<0.01),同时细胞色素c在胞浆中的表达量也明显下调(p<0.01)。结论 熊果酸作用BGC-823,可能使cofilin-1蛋白从胞质转位至线粒体内,促使细胞色素C释放,激活caspase级联反应,诱导细胞凋亡。

Abstract: Objective To investigate expression changes of cofilin-1 in cell BGC-823 treated with ursolic acid. Methods Cell BGC-823 was treated with ursolic acid, expression changes of cofilin-1 was detected by 2-D-electrophoresis and mass spectrum, protein expression of cofilin-1 and cytochrome c was detected by western blot. Results Lower expression of cofilin-1 in cytoplasm(p<0.01), but obvious raise in mitochondria(p<0.01), and down-regulation of cytochrome c in cytoplasm(p<0.01). Conclusions BGC-823 was treated with ursolic acid,might made cofilin-1 take transposition from cytoplasm to mitochondria,which promoted cytochrome c to release from mitochondria,activated caspase cascade,and induced cell apoptosis.
