GSK3B and diabetes mellitus: Akt deregulation has been implicated in diabetes.15 Glycogen synthase kinase‐3β (GSK3β) is a multifunctional kinase that plays crucial roles in various key biological processes, including cell proliferation, glycogen metabolism and neuronal function.16 GSK3β is considered a negative regulator in the insulin‐related signalling pathway, and GSK3β is inactivated when it is phosphorylated.
