摘要 目的探讨腺病毒5型E1A基因转染前后乳腺癌细胞相关指标水平的变化.方法:建立E1A 基因真核表达质粒pEGFp-E1A,然后进行E1A 基因转染乳腺癌细胞系,以获得稳定表达E1A 基因的转染细胞作为观察组,采用RT-PCR 进行E1A 基因mRNA 表达以及westem-blot的检测,比较组间基因表达情况.结果:转染基因E1A 基因以后,观察组的E1A-RNA 以及蛋白表达均较空白载体组以及对照组显著提高,而SK-BR-3 肿瘤细胞的HER-2/neu表达显著降低,而凋亡率显著增高(P〈0.05).结论:E1A 基因对于乳腺癌细胞的生长具有明显抑制作用,可作为乳腺癌基因治疗的重要靶点.
