1 Incubation of intact human neuroblastoma SH-SY5Y cells with VPA results in an increase in the subsequent in vitro recombinant GSK-3beta-mediated 32P incorporation into two putative GSK-3 substrates (approximately 85 and 200 kDa), compatible with inhibition of endogenous GSK-3beta by VPA. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
2 Incubation of intact human neuroblastoma SH-SY5Y cells with VPA results in an increase in the subsequent in vitro recombinant GSK-3beta-mediated 32P incorporation into two putative GSK-3 substrates (approximately 85 and 200 kDa), compatible with inhibition of endogenous GSK-3beta by VPA. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
3 Consistent with GSK-3beta inhibition, incubation of SH-SY5Y cells with VPA results in a significant time-dependent increase in both cytosolic and nuclear beta-catenin levels. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
4 GSK-3beta plays a critical role in the CNS by regulating various cytoskeletal processes as well as long-term nuclear events and is a common target for both lithium and VPA; inhibition of GSK-3beta in the CNS may thus underlie some of the long-term therapeutic effects of mood-stabilizing agents. Valproic Acid glycogen synthase kinase 3 beta Homo sapiens
