摘要 目的:探讨米非司酮对人子宫内膜癌细胞HEC-1-B体外增殖的影响及可能的作用机制。方法:体外培养人子宫内膜癌细胞HEC-1-B,不同浓度米非司酮处理细胞24~96 h后,用四甲基偶氮唑蓝比色法测定细胞增殖活性,流式细胞仪检测细胞周期,免疫组化方法检测凋亡相关蛋白Bcl-2和增殖相关抗原Ki-67蛋白的表达。结果:2.5 mg/L米非司酮作用72~96 h,5~20 mg/L米非司酮作用24~96 h,对人子宫内膜癌细胞HEC-1-B的生长有抑制作用(P<0.05),且呈明显的时间、浓度依赖性。5~20 mg/L米非司酮作用于HEC-1-B细胞24 h后,G0/G1期细胞概率上升,S期细胞概率下降(P<0.05),并呈明显的浓度依赖性,Bcl-2及Ki-67蛋白的表达水平亦下降(P<0.05),但无明显的浓度依赖性。结论:米非司酮能抑制人子宫内膜癌细胞HEC-1-B的生长,其机制可能与阻止细胞周期和促进细胞凋亡有关。
