摘要 目的探讨转化生长因子β1(TGF-β1)和细胞外信号调节激酶2(ERK2)在肺癌发生、发展中的作用。方法选取77份肺癌组织标本和20份肺良性病变组织标本。标本常规石蜡包埋行免疫组织化学染色,检测TGF-β1和ERK2蛋白表达。分析TGF-β1、ERK2蛋白表达与肺癌主要病理特征的关系。对TGF-β1与ERK2蛋白表达关系行Spearman等级相关分析。结果肺癌组织中TGF-β1、ERK2蛋白表达阳性率均明显高于肺良性组织,P均<0.05。TGF-β1、ERK2蛋白表达在低分化肺癌、淋巴结转移组织中的表达均明显高于高分化、中分化和无淋巴结转移组织。TGF-β1与ERK2表达呈明显正相关,P<0.000 1(r=0.646)。结论 TGF-β1、ERK2蛋白在肺癌组织中呈高表达,TGF-β1/ERK转导通路可能在肺癌的发生、发展及淋巴转移过程中起重要作用,检测二者水平有助于肺癌的病情判断。
