Mnk2和eIF4E在食管鳞状细胞癌中的表达及其临床意义

         

摘要

目的:探讨MAPK相互作用激酶-2(MAPK-interacting kinase-2,Mnk2)和真核细胞翻译起始因子4E ( eukaryotic initiation factor 4E,eIF4E)在食管鳞状细胞癌中的表达及其与食管鳞状细胞癌临床病理特征的关系。方法:收集临床食管鳞癌石蜡标本98例及正常食管黏膜上皮组织20例,应用免疫组化SP法检测癌组织及正常食管黏膜组织中Mnk2和eIF4E的表达,并分析其与食管鳞癌临床病理特征的关系。结果:Mnk2在食管癌组织中的阳性率68.4%(67/98),eIF4E的阳性率为61.2%(60/98),Mnk2与eIF4E表达呈正相关(P<0.05),且Mnk2蛋白过表达与食管鳞癌的浸润深度、病理分期密切相关( P<0.05)。结论: Mnk2在食管癌组织中的过表达与浸润深度、TNM分期有关,同时与eIF4E在食管癌的表达相关,两者在食管癌的发展中有协同作用。%AIM: To investigate the expression and significance of MAPK-interacting kinase-2 ( Mnk2 ) and eukaryotic initiation factor 4E ( eIF4E) in the patients with resected esophageal squamous cell carcinoma ( ESCC ). METHODS:The protein expression of Mnk2 and eIF4E in ESCC tissues (98 cases) and normal esophageal tissues (20 cases) were assessed by immunohistochemistry (IHC), and their correlations with clinicopathological features were statisti-cally analyzed.RESULTS:The over-expression rate of Mnk2 and eIF4E was 68.4%(67/98) and 61.2%(60/98), re-spectively.The expression of Mnk2 had a positive correlation with eIF4E (P<0.05).Clinicopathologic analysis showed that Mnk2 expression was significantly correlated with T classification ( P<0.05 ) and clinical stage ( P<0.05 ) .CON-CLUSION:The over-expression of Mnk2 was significantly related to the tumor invasive depth , TNM stages and expression of eIF4E in ESCC.Expression of Mnk2 and eIF4E may have a cooperative formation mechanism in the development of ESCC.
