摘要 目的研究DHA联合5-FU对肝癌细胞在抑制细胞增殖、诱导凋亡的影响。方法用Annexin-V-PE/PI荧光双标记法、Hoechst33258染色及JC-1线粒体膜电位检测法检测DHA、5-FU两药单用和联用对肝癌细胞HepG2增殖的影响。结果联合处理组细胞凋亡率较单独使用5-FU组或单独使用DHA均明显增加。Hoechst33258染色显示,5-FU联合DHA组细胞中出现明显的凋亡核表现,细胞凋亡率较单独采用5-FU及对照组细胞显著增高。JC-1线粒体膜电位检测结果显示,联合组细胞线粒体膜电位较单独使用5-FU组显著降低。结论 DHA联合5-FU对肝癌细胞的增殖抑制、诱导凋亡具有协同作用。
