GSK-3 Inhibitor IX (BIO) is a cell-permeable, highly potent, selective, reversible, and ATP-competitive inhibitor of GSK-3α and GSK-3β (IC50 = 5 nM). GSK-3 (Glycogen synthase kinase-3) plays important roles in numerous signaling pathways that regulate a variety of cellular processes including cell proliferation, differentiation, apoptosis and embryonic development. GSK-3 Inhibitor IX also inhibits PKB Kinase (phosphoinositide-dependent kinase 1 PDK1 or PDPK1), a master kinase responsible for the activation of AKT/PKB, PKC, p70 S6 kinase (S6K) and SGK (serum/glucocorticoid regulated kinase). Research shows that PKB Kinase inhibition halts endothelial cell migration. GSK-3 Inhibitor IX has been been widely-used in embryonic stem cell studies to maintain human embryonic stem cells in their undifferentiated state, and to sustain expression of the pluripotent state-specific transcription factors Oct-3/4, Rex-1 and Nanog. GSK-3 Inhibitor IX may act to induce the differentiation of neonatal cardiomyocytes and maintain self-renewal in both human and mouse embryonic stem cells through wnt signaling activation.
