摘要 目的雌激素受体α(ERα),其剪切变异体为ERΔE5,在正常乳腺组织和乳腺癌中,通过检测其表达水平,探讨研究ERΔE5在乳腺癌组织中的表达水平和其对临床的指导意义。方法实验采用普外科的59例乳腺癌组织和59例正常乳腺组织,应用逆转录聚合酶链式反应(RT-PCR)检测目的基因ERΔE5。培养乳腺癌细胞株作为阳性对照,分析ERΔE5在乳腺癌组织和正常乳腺组织的差异,研究其临床意义。结果在乳腺癌标本中ERΔE5与HER-2显著相关(P<0.0001)。在乳腺癌标本与正常乳腺组织中ERΔE5的表达水平,两者检测水平有统计学意义(P<0.0001)。并且ERΔE5的表达与临床分期无相关性。结论 ERΔE5的水平在乳腺癌组织中显著增高,HER-2表达与其呈正相关,因此ERΔE5可以作为新的临床预后指标,并指导临床内分泌治疗。
