Phosphatidylinositol-3 kinase (PI3-K) and proteins kinase B (Akt) activation not merely stimulate NO creation, however they also inhibit glycogen synthase kinase-3 (GSK3) (8). Likewise, activation of canonical Wnt signaling inactivates GSK3 (9). Wnts are secreted glycoproteins recognized to regulate hematopoiesis and stem cell function (9). In the unstimulated cell, GSK3 phosphorylates and accelerates degradation of… Continue reading Phosphatidylinositol-3 kinase (PI3-K) and proteins kinase B (Akt) activation not merely
