Defects in the regulation of beta-catenin in colorectal cancer

Adv Exp Med Biol. 1999;470:23-32. doi: 10.1007/978-1-4615-4149-3_3.


The molecular events that contribute to the progression of colon cancer are beginning to unravel. An initiating and probably obligatory event is the oncogenic activation of beta-catenin. This can come about by the loss of its negative regulator the adenomatous polyposis coli (APC) protein, or by mutations in the beta-catenin gene that result in a more stable protein product. The interaction between APC and beta-catenin, and additional proteins that affect assembly and signaling along this pathway, are discussed.
