摘要: 目的 探讨胃腺癌中HMGA2、Twist的表达及其与上皮间质转化相关因子E-cadherin和Vimentin的关系。方法 应用免疫组织化学方法检测80例胃腺癌标本以及20例正常胃组织中HMGA2、Twist、E-cadherin和Vimentin的表达,分析其与临床病理资料之间的关系。结果 80例胃腺癌组织中,HMGA2、Twist、E-cadherin和Vimentin表达的阳性率分别为65%、68.75%、26.25%和67.5%,HMGA2和Twist的表达呈正相关(P<0.05),HMGA2与Twist的表达均与淋巴结转移及肿瘤临床分期有统计学意义(P<0.05),而且HMGA2和Twist的表达均与E-cadherin低表达(P<0.05)和Vimentin高表达(P<0.05)存在相关性。结论 HMGA2与Twist在胃腺癌组织中的高表达与EMT的发生密切相关,通过促进胃腺癌组织上皮表型向间质表型转化进而促进侵袭转移。

Abstract: Objective To investigate the expressions of HMGA2 and Twist in gastric adenocarcinoma and their association of pithelial-mesenchymal transformation(EMT)-related makers of E-cadherin and Vimentin.Methods Expressions of HMGA2,Twist、E-cadherin and Vimentin in 80 cases of gastric adenocarcinoma and in 20 cases of normal gastric tissues were assayed by immunohistochemical staining(IHC).We also compared with clinicopathological data.Results HMGA2,Twist、E-cadherin and Vimentin positive expression rates were 65%,68.75%,26.25% and 67.5%,respectirely,in gastric adenocarcinoma.The expression of HMGA2 was positively correlated with that of Twist(P<0.05).The expressions of HMGA2 and Twist were significantly correlated with lymph node metastasis and TNM stage(P<0.05),the low expression of E-cadherin(P<0.05)and the increased expression of Vimentin(P<0.05).Conclusion HMGA2 and Twist over-expressed in gastric adenocarcinoma,and related to EMT.It promotes epithelial-mesenchymal transitions phenotype,and then induces invasion and metastasis of gastric adenocarcinoma.
