摘要 目的 研究人食管鳞癌及癌旁正常食管黏膜组织中细胞外信号调节激酶 (ERK1 / 2 )及其活化态 (p -ERK1 / 2 )的表达 ,探讨ERK1 / 2活化与人食管鳞癌病理特征的关系及其在人食管鳞癌发生发展中的意义。方法 应用westernblot方法和免疫组织化学方法检测 6 0例人食管鳞癌组织及癌旁正常组织中的ERK1 / 2及p -ERK1 / 2蛋白的表达情况。结果 食管鳞癌组织与癌旁正常黏膜组织中的ERK1 / 2的蛋白水平无明显差异 ,p -ERK1 / 2明显增高 ,分别为癌旁正常黏膜组织的 1 30倍和 1 2 0倍 (t=1 7 2 3,t=1 8 1 8,P <0 0 1 )。p -ERK1 / 2在不同病理分期食管鳞癌中的表达无明显差异 ,而与分化程度有关 (P <0 0 1 )。结论 细胞外信号调节激酶的活化与食管鳞癌的分化有关 ,与食管癌病理分期无关 。
