摘要 [目的]观察恩度、紫杉醇对Her-2过表达乳腺癌细胞MDA-MB-453的诱导凋亡作用。[方法]免疫组化法检测乳腺癌细胞MDA-MB-453的Her-2表达水平,用流式细胞仪检测细胞凋亡率,比较恩度、紫杉醇单独及联合作用于MDA-MB-453细胞24、48h的细胞凋亡率。[结果]MDA-MB-453细胞Her-2表达率95%可信区间为63.32%~69.60%;恩度与紫杉醇对MDA-MB-453细胞均有诱导凋亡作用,并成剂量依赖关系,其中以恩度50μg/ml联合紫杉醇50nmol/L作用48h组凋亡率最高。[结论]体外环境下恩度、紫杉醇均可诱导Her-2过表达乳腺癌细胞凋亡,且呈剂量依赖关系,两药联合时凋亡作用增强。
