Beta-catenin regulates myogenesis by relieving I-mfa- mediated suppression of myogenic regulatory factors in P19 cells.

Wnt/beta-catenin signaling plays a critical role in embryonic myogenesis. Here we show that, in P19 embryonic carcinoma stem cells, Wnt/beta-catenin signaling initiates the myogenic process depends on beta-catenin- mediated relief of I-mfa (inhibitor of MyoD Family a) suppression of myogenic regulatory factors (MRFs). We found that beta-catenin interacted with I-mfa and that the interaction was enhanced by Wnt3a. In addition, we found that the interaction between beta-catenin and I-mfa was able to attenuate the interaction of I-mfa with MRFs, relieve I-mfa-mediated suppression of the transcriptional activity and cytosolic sequestration of MRFs, and initiate myogenesis in a P19 myogenic model system that expresses exogenous myogenin. This work reveals a mechanism for the regulation of MRFs during myogenesis by elucidating a beta-catenin-mediated, but lymphoid enhancing factor-1/T cell factor independent, mechanism in regulation of myogenic fate specification and differentiation of P19 mouse stem cells.[1]
