Thus, presenilin deficiency results in increased beta-catenin stability in vitro and in vivo by disconnecting the stepwise phosphorylation of beta-catenin, both in the presence and absence of Wnt stimulation

:
These results underscore the importance of the endosomal pathway in canonical Wnt signaling and reveal a mechanism for regulation of Wnt signaling by presenilin deficiency
