In recent years,Wnt/β-catenin signaling has been identified as a key player in embryogenesis and human diseases.Canonical Wnt signaling pathway is controlled by a variety of classic molecules like Wnt,β-catenin,Axin,APC,GSK-3β and CK1,which interact and coordinate to regulate the expressions of cell signaling molecules.The latest evidences suggest that some components of the Wnt/β-catenin signaling,like APC,GSK-3β,CK1,Dkk2 and WISE,play dual roles different from what they have been thought previously.Here we reviewed some recent discoveries on the canonical Wnt/β-catenin signaling pathway to provide some new ideas and principles for signaling transduction studies.
