abstract：:The Wnt signaling pathway plays a major role in development, and upon deregulation it is implicated in neoplasia. The hallmark of the canonical Wnt signal is the protection of beta-catenin from ubiquitination and proteasomal degradation induced by glycogen synthase kinase (GSK)-3beta inhibition. The stabilized beta-ca...
