Expression of MHC class I antigen in Morris rat hepatoma and normal liver
1Department of Biochemistry, Faculty of Medicine, National University of Singapore.
Expression of major histocompatibility complex (MHC) class I antigen in Morris rat hepatoma 7777 and normal rat liver tissues was studied by immunohistochemical techniques, Western blot and radiobinding assay. It was found that hepatoma tissue displayed a pattern of enhanced MHC class I antigen expression compared with normal liver. This phenomenon may represent an uncommon pattern of MHC class I antigen expression of liver tumor. The influence of enhanced MHC class I antigen expression on the development and spread of tumors as well as the possible mechanisms of this enhancement are discussed.
