APC

The APC gene encodes the adenomatous polyposis coli protein. It is also commonly known as "the gatekeeper of the colon" due to its crucial role in maintaining normal cell growth. APC functions mainly through regulating the Wnt signaling pathway. By interacting with β - catenin, it promotes its degradation, thereby preventing abnormal cell proliferation.
Mutations in APC are strongly linked to familial adenomatous polyposis (FAP), a hereditary condition that significantly increases the risk of colorectal cancer. In drug development, targeting the APC - related Wnt pathway is a promising area. Some small - molecule inhibitors are under research to correct the dysregulated signaling caused by APC mutations.
