摘要
目的:探究姜黄素杀伤HPV阳性宫颈癌细胞的作用机制。方法:采用细胞活性检测实验和细胞凋亡检测实验分析姜黄素对HPV阳性宫颈癌细胞活性以及细胞凋亡的影响;采用实时定量PCR实验和蛋白质印迹(Western blot)法检测姜黄素促进HPV阳性宫颈癌细胞凋亡过程中关键信号通路因子LncRNA MEG3、miR-21、PTEN和活化的caspase3的变化水平。结果:姜黄素显著促进了HPV阳性宫颈癌细胞凋亡,升高了LncRNA MEG3、PTEN和活化的caspase3的表达水平,下调了miR-21的表达(P<0.05);利用siRNA敲低Lnc RNA MEG3的表达,能够逆转姜黄素对miR-21、PTEN和caspase3的调控(P<0.05)。结论:姜黄素可能通过上调LncRNA MEG3而降低miR-21的表达,从而上调PTEN的表达,最终促进HPV阳性宫颈癌细胞的凋亡。
