Future research will therefore demonstrate how important the Wnt–β-catenin signalling pathway is for the self-renewal of cancer stem cells. The past two decades have seen a number of cases in ...
Frizzled (FZD) proteins are the principal receptors of the Wnt signaling pathway. However, whether Wnt ligands induce FZD endocytosis and degradation remains elusive. The transmembrane E3 ubiquitin ...
