Abstract： 目的:探讨染料木黄酮与顺铂联用对耐药卵巢癌细胞系SKOV-3增殖与凋亡的影响. 方法:采用MTT比色法检测染料木黄酮和顺铂联用对SKOV-3细胞增殖的影响,Hoechst染色荧光显微镜下观察联合用药后细胞形态的改变,流式细胞仪分析细胞周期并检测凋亡率. 结果:联用不同浓度的染料木黄酮后顺铂对SKOV-3细胞IC50降低率为32.3%～79.8%,两药联合作用系数在0.586～0.869之间,为轻度至高度协同作用. 染料木黄酮与顺铂联用可显著提高凋亡率,两药联用诱导SKOV-3细胞凋亡和阻滞G2/M期、干扰S期进程,凋亡率与G1期细胞比例呈负相关(rs=-0.953, P<0.05). 结论: 染料木黄酮可以增强顺铂对SKOV-3细胞的增殖抑制作用和杀伤作用,两种药物具有协同作用. 染料木黄酮阻滞细胞于G2/M期并同时干扰S期进程可能是两药发挥协同作用的重要机制.
