摘要 目的探讨姜黄素对人肝癌细胞株(SSMC7721)细胞的诱导分机制,为肝癌的治疗提供理论依据。方法应用噻唑蓝(MTT)比色法检测姜黄素对SSMC7721细胞的增殖抑制率,流式细胞仪检测细胞周期进程的变化及凋亡率,透射电子显微镜观察SSMC7721亚细胞结构改变。结果姜黄素对SSMC7721细胞有明显的增殖抑制作用,且呈剂量依赖性,流式细胞仪分析G1期细胞增多,S期细胞减少,G2/M期细胞相对增多,电子显微镜下可见经姜黄素作用后的细胞高度空化,线粒体肿胀,核染色质趋边,可见凋亡小体。结论姜黄素能够抑制SSMC7721细胞增殖,阻止SSMC7721细胞G1期向S期转化进程,诱导SSMC7721细胞凋亡及亚细胞结构改变。
