摘要
目的研究双氢青蒿素对前列腺癌PC-3细胞的凋亡诱导作用,并探讨其可能的机制。方法MTT法测定不同浓度双氢青蒿素对PC-3细胞增殖的影响,流式细胞仪(FCM)、透射电镜(TEM)观察双氢青蒿素对PC-3细胞的凋亡诱导作用,免疫组化(SP)检测双氢青蒿素对PC-3细胞内Bax、Bcl-2蛋白阳性表达的影响。结果双氢青蒿素对PC-3细胞有明显增殖抑制效应,能诱导PC-3细胞凋亡且具有浓度-时间依赖性,导致PC-3细胞线粒体肿胀、核碎裂、凋亡小体形成;随着双氢青蒿素浓度的增加,Bcl-2蛋白阳性表达降低,而Bax蛋白阳性表达增加。结论双氢青蒿素可能通过上调Bax,下调Bcl-2蛋白表达诱导前列腺癌PC-3细胞凋亡。
