Relationship Between βCatenin，Adenomatous Polyposis Coli Genes and Tumors

Objective To discuss the molecular structures and functions of βCatenin and APC (Adenomatous polyposis coli) genes, as well as the roles they played during the carcinogenesis and progression of tumors. MethodsAdvances in molecular biology and oncology of βCatenin and APC genes in recent years has been reviewed. ResultsHigh expression of βCatenin and APC genes was an early event during the carcinogenesis due to the abnormal regulation of βCatenin and APC genes. But on the contrary, the low expression of these two genes was probably associated with the progression of tumors. Moreover, βCatenin and APC genes could also regulate the expression of p53,cmyc genes and cyclin D1. Conclusion βCatenin and APC genes may play a key role during the carcinogenesis and progression of tumors and modulate other oncogen/suppressor gene and factors.
