T细胞活化连接蛋白和血管内皮生长因子在正常肝组织、肝硬化及肝癌中的表达及关系的探讨

Expressions of LAT and VEGF in normal liver tissue, cirrhosis, hepatocellular carcinoma and the relationship between them

目的分析T细胞活化连接蛋白（LAT）和血管内皮生长因子（VEGF）在原发性肝细胞性肝癌（HCC）中的表达及两者之间的关系。方法分别应用免疫组化S-P法检测HCC50例、肝硬化30例、正常肝组织10例中LAT蛋白、VEGF蛋白的表达情况。结果LAT和VEGF在HCC、肝硬化和正常肝组织中的表达差异有统计学意义（P〈0．05），LAT在HCC中的表达高于肝硬化（P〈0．05），而VEGF在肝硬化组织中的表达高于HCC中的表达（P〈0．05）。结论经统计分析LAT、VEGF在HCC中的表达关系不密切；但LAT和VEGF各自的异常表达与HCC的发展密相关，在HCC的发生、发展过程中起非常重要的作用。

Objective To explore the expressions of LAT and VEGF, and the relationship between them in hepatocellular carcinoma （HCC）. Methods The expressions of LAT protein and VEGF protein in 50 HCC, 30cirrhosis and 10 normal tissues were assessed by immunohistochemical method. Results The expressions of LAT and VEGF in cancer tissues, cirrhosis tissues, normal tissues were significantly different. The expression of LAT in HCC tissues was stronger than that in cirrhosis, but the expression of VEGF in cirrhosis was stronger than that in HCC tissues. Conclusion The expression of LAT was not closely associated with the expression of VEGF in HCC. The abnormal expressions of LAT and VEGF were closely associated with the development of HCC. They may play important roles in development of HCC.
