Tcf-3 expression and β -catenin mediated transcriptional activation in aggressive fibromatosis (desmoid tumour)

Abstract

Aggressive fibromatosis harbours mutations resulting in β-catenin protein stabilization. Primary cell cultures demonstrate constitutive tcf activation in aggressive fibromatosis. Expression and co-immunoprecipitation studies suggest that β-catenin binds and activates tcf-3 in this tumour. This is the first demonstration of tcf-3 activation by β-catenin stabilization in a human neoplastic process. © 2001 Cancer Research Campaign http://www.bjcancer.co
