摘要 [目的]研究毛兰素诱导胃癌细胞SGC-7901凋亡的机制。[方法]MTT法检测毛兰素对人胃癌细胞SGC-7901的增殖抑制作用,Annexin-Ⅴ/PI双染色法流式细胞仪检测细胞凋亡率,PI染色法流式细胞仪定量检测细胞周期分布变化,同时比色法检测细胞caspase-3活性变化。[结果]毛兰素能明显抑制胃癌细胞SGC-7901增殖,且呈浓度依赖关系,48hIC50值为0.056μg/ml;毛兰素能诱导胃癌细胞SGC-7901凋亡且呈时间和浓度依赖性,使细胞周期阻滞于S期,但未见caspase-3激活。[结论]毛兰素能诱导胃癌细胞SGC-7901凋亡,可能与使细胞周期阻滞于S期有关,但未见caspase-3激活。
