1、592ChineseJournalofWomanandChildHealthResearch,2014,Vo1.25No.4依达拉奉对卵巢癌顺铂耐药细胞系A2780CP耐药性的影响韩黎,汪宏波,李艳辉,朱燕(华中科技大学同济医学院附属协和医院妇产科,湖北武汉430022)[摘要]目的研究依达拉奉对卵巢癌耐药细胞株A2780CP增殖、凋亡及其对顺铂敏感性的影响。方法选取顺铂和依达拉奉的血药峰值浓度作为联合用药的基础,将实验分为顺铂处理A2780细胞组、顺铂处理A2780CP细胞组、依达拉奉处理A2780CP细胞组、顺铂及依达拉奉联合处理A2780C
2、P细胞组,对照组。培养一定时间后用MTI"法检测细胞相对活性,流式细胞仪分析细胞的凋亡状况。结果顺铂及依达拉奉联合处理的A2780CP细胞生长明显慢于单独2780CP细胞,顺铂及依达拉奉联合处理的A2780CP细胞对顺铂的敏感性增加(P=0.016<0.05);AnnexinV—FITC/P1分析显示,药物作用24小时后,顺铂及依达拉奉联合处理A2780CP细胞能提高细胞凋亡率(P:0.037<0.05)。结论依达拉奉能显著提高A2780CP细胞对顺铂的敏感性,对顺铂耐药性有一定逆转作用。[关键词]依达拉奉;顺铂;联合;卵巢癌;耐药性doi:10
