Subcellular distribution of Wnt pathway proteins in normal and neoplastic colon

Abstract excerpt

Mutations in the APC tumor suppressor gene are present in approximately 85% of colorectal tumors and are thought to contribute early in the process of tumorigenesis. The truncated protein resulting from most APC mutations can lead to elevated beta-catenin levels in colon tumor cells. APC and associated proteins thus form a beta-catenin regulatory complex, with axin playing a key role. Although cell culture...
