摘要 目的观察真核生物翻译起始因子2α(eukaryotic translation initiation factor 2α,e IF2α)在胃腺癌中的表达,探讨其在不同临床特征中的表达差异及临床意义。方法选取华北理工大学附属医院确诊为胃腺癌,并行手术根治的患者48例作为观察组,同时选取距肿物边缘>5 cm的非肿瘤性胃黏膜组织29例作为对照组,应用免疫组化法检测两组中e IF2α的表达,分析其在不同临床病理特征中的表达差异。结果 e IF2α在观察组中的阳性率为37.5%(18/48),明显高于其在对照组中的阳性率0(0/29)(P<0.05)。观察组中e IF2α表达与患者性别、年龄、Lauren分型、分化程度、是否有癌栓、是否有癌结节、淋巴结转移及浸润深度分组中的差异均无统计学意义(P>0.05)。结论 e IF2α在胃腺癌组织中高表达,其作用可能与去磷酸化有关,对病变的形成可能有一定的促进作用。
