1 Regulation of Akt and glycogen synthase kinase-3 beta phosphorylation by sodium valproate and lithium. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
2 This study tested if sodium valproate or lithium, two agents used to treat bipolar mood disorder, altered the regulatory phosphorylations of Akt or glycogen synthase kinase-3beta (GSK3beta) in human neuroblastoma SH-SY5Y cells. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
3 This study tested if sodium valproate or lithium, two agents used to treat bipolar mood disorder, altered the regulatory phosphorylations of Akt or glycogen synthase kinase-3beta (GSK3beta) in human neuroblastoma SH-SY5Y cells. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
4 Treatment with sodium valproate caused a gradual but relatively large increase in the activation-associated phosphorylation of Akt on Ser-473, and a similarly gradual but more modest increase in the inhibition-associated phosphorylation of GSK3beta on Ser-9. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
5 Two other inhibitors of histone deacetylase, a recently identified target of sodium valproate, also caused gradual increases in the phosphorylation of Akt and GSK3beta. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
6 These results identify novel effects of sodium valproate on the Akt/GSK3beta signaling pathway, indicating that histone deacetylase inhibition is linked to activation of Akt, and show that two anti-bipolar agents have a common action, the increased inhibitory phosphorylation of Ser-9-GSK3beta. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
