摘要 [目的]探讨转移相关基因1(metastasis associated gene1,MTA1)在乳腺癌浸润与转移中作用。[方法]用逆转录聚合酶链反应(RT-PCR)技术联合ZymedTM免疫组化方法分别检测55例乳腺癌、癌旁组织中MTA1 mRNA和蛋白表达情况。[结果]MTA1 mRNA在乳腺癌中阳性表达率为52.7%(29/55),在癌旁乳腺组织的阳性率23.6%(13/55);两者比较差异有统计学意义(P<0.05)。MTA1蛋白在乳腺癌组织中阳性表达率为49.1%(27/55),在癌旁乳腺组织中阳性表达率为16.4%(9/55);两者比较有统计学差异(P<0.01)。MTA1在乳腺癌组织中的阳性检出率与临床分期、淋巴结转移数目(>4)、病理分级和c-erbB-2阳性相关(P<0.05),与年龄、ER、PR无明显关系(P>0.05)。[结论]MTA1对乳腺癌浸润、转移可能有促进作用,有可能成为预测乳腺癌浸润与转移的参考指标。
