摘要 目的:观察棉酚在体外对人胃癌细胞株MGC-803细胞增殖、凋亡及AIF表达的影响。方法:MTT法检测细胞增殖、AO/EB双染法和流式细胞仪Annexin VFITC/PI双染法检测细胞凋亡情况,Western blot检测AIF表达情况。结果:棉酚能有效抑制MGC-803细胞增殖,呈一定时效关系。其在24、48、72 h的IC50分别为57.58、53.92、39.10μmol/L。AO/EB双染法和Annexin VFITC/PI双染法检测结果显示棉酚在10、40、80μmol/L作用24 h后能明显促进人胃癌MGC-803细胞凋亡。Western blot结果显示,棉酚使人胃癌MGC-803细胞中AIF在线粒体中表达量减少,细胞核中表达量增加。结论:棉酚可诱导人胃癌MGC-803细胞凋亡。
