I think that if SM04554 only was a GSK3B inhibitor dont work... For example, I dont know anyone who had results with VPA
From the company website:
SM04690 treatment decreased the expression of Wnts signaling activators and downstream genes, e.g. Wnt3a, Dvl, Axin2, TCF4, TCF7, APC. GSK3β, CyclinD1 etc. as compared to vehicle
SM04690 treatment increased the expression of Wnt pathway inhibitors e.g. DKK1, 2, WIF1 etc. as compared to vehicle.
