摘要 目的探讨研究血清反应因子(SRF)、锌指转录因子Slug和E-钙粘蛋白(E-cadherin)在非小细胞肺癌(NSCLC)中表达及其临床意义。方法采用免疫组织化学染色法检测47例NSCLC组织中SRF、Slug和E-cadherin蛋白的表达情况。结果 SRF、Slug的阳性表达和E-cadherin的异位或缺失表达在NSCLC组织中阳性表达率分别为57.45%(27/47)、68.09%(37/47)和78.72%(37/47),显著高于癌旁组织的10.64%、23.40%和25.53%,差异均具有显著性(P<0.05)。其中SRF蛋白表达与NSCLC分化程度、临床分期密切相关(P<0.05);Slug蛋白表达与NSCLC分化程度、临床分期和有无淋巴结转移密切相关;有74.07%(20/27)SRF阳性表达同时伴有E-cadherin的异位表达(P<0.05);而有96.88%(31/32)Slug阳性表达同时伴有E-cadherin的异位表达,但差异无显著性(P>0.05)。结论 SRF、Slug的阳性表达和E-cadherin的异位或缺失表达对促进NSCLC发生、发展具有重要意义,可能是NSCLC发生上皮-间质转化的重要机制之一。
