Abstract excerpt
Beta-catenin is a component of stable cell adherent complexes whereas its free form functions as a transcription factor that regulate genes involved in oncogenesis and metastasis. Free beta-catenin is eliminated by two adenomatous polyposis coli (APC)-dependent proteasomal degradation pathways regulated by glycogen synthase kinase 3beta (GSK3 beta) or p53-inducible Siah-1. Dysregulation of beta-catenin turnover...
