摘要
Mutations in APC have been identified in up to 80% of 'classic' sporadic colorectal cancers. Although the APC gene was first sequenced over a decade ago, new functions are still being described and its importance in the genesis of colorectal cancer continues to increase. The current focus of attention is on the APC/beta-Catenin/TCF signal transduction pathway as the main effector mechanism, and recent work has also implicated this pathway in the aetiology of the minority of CRCs that develop through mismatch repair. At the same time, new evidence on the interactions of APC with the cytoskeleton and the demonstration of a nuclear export function in the protein have shown that it has multiple additional roles in colorectal carcinogenesis. Thus this is an area that benefits from further review of the ever expanding literature.
