摘要 目的:评价漆树酸和紫杉醇联合用药对人肝癌HepG2细胞是否具有协同作用。方法:人肝癌HepG2细胞经漆树酸和(或)紫杉醇处理后,MTS法检测细胞增殖情况,流式细胞仪技术检测细胞凋亡,Westernblot方法检测Bax、Bcl-2及Caspase-3、8、9和PARP凋亡相关蛋白的变化。结果:漆树酸和紫杉醇联合应用能够明显增强对HepG2细胞的增殖抑制,与单独用药组相比具有明显的协同作用。漆树酸联合紫杉醇可以明显诱导HepG2细胞凋亡。两药联合作用可以诱导Bax表达增加,Bcl-2表达减少,Bax/Bcl-2比率增加,引起Caspase-3、8、9的活化,PARP的切割。结论:漆树酸和紫杉醇联合用药具有协同作用,明显增强抑制HepG2细胞的增殖和诱导细胞凋亡,其作用机制可能与Caspase系统活化相关。
