摘要 目的观察姜黄素对肝癌细胞Huh7中Bcl-2家族成员表达,cytochromec胞内定位以及caspase-3活化的影响,探讨姜黄素诱导肝癌细胞凋亡的分子机制。方法Western blotting分析姜黄素处理Huh7细胞后Bcl-2、Bcl-xL、Bad、Bid、Beclin、Bag-1和caspase-3蛋白表达的变化;间接免疫荧光技术观察在姜黄素干预后Bad和cytochromec蛋白的定位及变化。结果25μmol/L的姜黄素明显上调Huh7细胞中Bad的表达水平,但是对Bcl-2、Bcl-xL、Bid、Beclin和Bag-1的表达并无显著影响。同时,姜黄素能够促使cytochromec从线粒体释放至胞浆中,以及诱导caspase-3的活化。结论姜黄素通过激活线粒体凋亡通路诱导肝癌细胞Huh7凋亡。
