Insulin-induced GSK-3beta phosphorylation is mediated by the phosphatidylinositol 3-kinase/Akt signaling pathway. PE treatment does not activate phosphatidylinositol 3-kinase or Akt (Ballou, L.

Indeed, PE treatment of Rat-1 cells increased the activity of atypical PKCzeta, and expression of PKCzeta in COS-7 cells stimulated GSK-3beta Ser-9 phosphorylation. In addition, PE-induced GSK-3beta phosphorylation was reduced in Rat-1 cells treated with a cell-permeable PKCzeta pseudosubstrate peptide inhibitor.
