摘要
目的 研究人乳腺癌组织以及癌旁正常乳腺组织中雌激素受体 (ER)亚型ERα和ERβ的表达 ,及其在乳腺癌发生发展中的作用。方法 应用逆转录聚合酶链反应方法检测 30例患者乳腺癌组织以及相应癌旁正常组织中ERα和ERβ的mRNA的表达情况。结果 ERα在人乳腺癌组织的表达明显高于癌旁正常组织 (t=7 399,P <0 0 1) ,ERβ在人乳腺癌组织的表达明显低于癌旁正常组织 (t=- 3 2 36 ,P <0 0 1) ,ERα/ERβ比值在人乳腺癌组织明显高于癌旁正常组织 (t =6 385 ,P <0 0 1) ;没有淋巴结转移的乳腺癌患者ERα/ERβ比值明显高于有淋巴结转移的乳腺癌患者 (t =2 6 0 2 ,P <0 0 5 ) ;在分期较晚的肿瘤ERα/ERβ比值明显低于分期较早的肿瘤 (t =3 75 4 ,P <0 0 5 )。结论 ERα在乳腺癌发生发展过程中与ERβ发挥不同的作用 ,并有可能成为乳腺癌基因治疗的新靶点。
