溶酶体膜蛋白LAMP3对肝癌转移影响的研究进展

摘要

原发性肝细胞肝癌（ hepatic cell carcinoma，HCC）是广西区域性高发恶性肿瘤，其预后与肝癌是否转移密切相关。目前有研究发现溶酶体膜相关蛋白LAMP3在肝癌细胞稳定过表达后，可促进肝癌细胞的转移，同时诱导细胞骨架F-actin重排并上调Cdc42活性，提示LAMP3可能是肝癌转移的促进因子。本文就溶酶体膜蛋白LAMP3对肝癌转移的意义作一综述。%Hepatic cell carcinoma( HCC)was regional and high incidence of malignant tumor in Guangxi Province, the prognosis was closely related with metastasis whether or not. At present,some studies have discovered that lyso-some-associated membrane proteins( LAMP3 )stable over expression in hepatocellular carcinoma cells,which could promote the metastasis,at the same time induced cytoskeletal F-actin rearrangement and upregulation of Cdc42 ac-tivity. Results suggest that LAMP3 is a metastasis promoting factor. The lysosomal membrane protein LAMP3 on liver metastasis were reviewed in this article.
