摘要 目的观察乳腺癌组织中胰腺十二指肠同源盒-1(PDX-1)蛋白及mRNA的表达变化。方法采用免疫组化EnVision法及实时定量RT-PCR检测乳腺癌、乳腺良性病变及癌旁乳腺组织中的PDX-1蛋白及mRNA。结果PDX-1蛋白在乳腺癌组织中的阳性表达率为41.5%,在癌旁乳腺组织、良性病变组织中无表达,前者与后两者相比,P均<0.05。乳腺癌组织、癌旁乳腺组织和乳腺良性病变组织中PDX-1 mRNA分别为1.15±1.66、0.02±0.04、0.27±0.36,前者与后两者相比,P均<0.05。PDX-1蛋白的表达与乳腺癌淋巴结转移、分化程度和临床分期有关(P均<0.05)。结论乳腺癌组织中PDX-1蛋白及mRNA表达增加,与乳腺癌转移及预后有关。
