摘要 目的探讨N-myc下游调节基因(N-myc downstream-regulated gene-1,NDRG1)的编码蛋白NDRG1和E-cadherin(钙粘素)蛋白在直肠腺癌中的表达及其临床病理意义。方法应用免疫组化法检测80例直肠腺癌和12例直肠腺瘤组织中NDRG1和E-cadherin蛋白的表达情况。结果(1)直肠腺癌和直肠腺瘤组织中NDRG1阳性表达率分别为77.5%和50.0%,E-cadherin蛋白阳性表达率分别为53.8%和91.7%;(2)在TNMⅢ-Ⅳ期和淋巴结转移组,NDRG1蛋白阳性表达率为95.0%,明显高于TNMⅠ~Ⅱ期和无淋巴结转移组的60.0%;在浆膜和浆膜外浸润组,NDRG1蛋白阳性表达率为82.8%,高于肌层以内浸润组的63.6%,统计学处理,差异有显著性(P〈0.05);E-cadherin蛋白阳性表达率在高-中分化直肠腺癌组为58.8%,明显高于低分化组的25.0%;而在TNMⅢ~Ⅳ期和有淋巴结转移组,为32.5%,低于TNMⅠ-Ⅱ期和无淋巴结转移组75.0%,差异有统计学意义(P〈0.05)。结论NDRG1可能作为潜在癌基因在直肠腺癌进展过程中起一定作用,检测NDRG1和E-cadherin蛋白的表达有助于判断直肠腺癌生物学行为及恶性程度。
