摘要 目的 探讨紧密连接蛋白ZO-1在人乳腺癌组织中的表达情况及其临床意义。方法 选择良性乳腺疾病患者34例和乳腺癌患者104例,乳腺癌患者按TNM分期Ⅰ期26例、Ⅱ期45例、Ⅲ期33例;按肿瘤大小〈2 cm 34例、2~5 cm 57例、〉5 cm 7例;无腋窝淋巴结转移41例,有腋窝淋巴结转移63例;Her-2表达阴性67例、Her-2表达阳性37例。采用免疫组化SP法检测良、恶性乳腺疾病组织中ZO-1的蛋白表达,并分析乳腺癌组织中ZO-1表达与肿瘤的侵袭和转移之间的关系。结果 人乳腺癌组织中ZO-1蛋白的阳性表达明显低于良性乳腺疾病组织(P〈0.05),且乳腺癌组织中ZO-1的异常表达与TNM分期、腋窝淋巴结转移及Her-2表达相关(P〈0.05),但与肿瘤大小无关(P〉0.05)。结论 人乳腺癌组织中ZO-1蛋白表达下调,并可能参与肿瘤细胞的侵袭和转移,可作为乳腺癌预后的候选标志物之一。
