Abstract:
Carbonic anhydrase(CA) is one of a group of enzyme that contains zinc. They exist widely in the mammals. CA has at least 14 species of isoenzyme. Among them,CAIX is located at the downstream of VHL tumor suppressor gene,and it can be activated through HIF-1 pathway. CAIX primarily exists in the mucous membrane of gastrointestinal tract in normal human tissues and its expression is low. However,higher expression of CAIX can be detected in renal cell carcinoma,cervical carcinoma and lung cancer,it may be closely related with the occurrence and development of the tumor. In addition,we can predict the prognosis of tumor patients by analysis of the expression of CAIX,thus,it is considered that CAIX is a tumor specifi c antigen. Due to its highly specifi c expression in renal cell carcinoma,CAIX will become the potential target antigen of tumor vaccine as well as the target gene for the treatment of RCC. The application of CAIX shows high promise in RCC target therapy. Hence,it is defi nitely important for us to investigate the expression and regulation of the CAIX.
