1 Farrerol Directly Targets GSK-3beta to Activate Nrf2-ARE Pathway and Protect EA.hy926 Cells against Oxidative Stress-Induced Injuries. farrerol glycogen synthase kinase 3 alpha Homo sapiens
2 Our results demonstrated that farrerol could specifically target Nrf2 negative regulator GSK-3beta and inhibit its kinase activity. farrerol glycogen synthase kinase 3 alpha Homo sapiens
3 Mechanistic studies proved that farrerol could induce an inhibitory phosphorylation of GSK-3beta at Ser9 without affecting the expression level of total GSK-3beta protein and promote the nuclear translocation of Nrf2 as well as the mRNA and protein expression of its downstream target genes heme oxygenase-1 (HO-1) and NAD(P)H: quinone oxidoreductase 1 (NQO1) in EA.hy926 cells. farrerol glycogen synthase kinase 3 alpha Homo sapiens
4 Further studies performed with GSK-3beta siRNA and specific inhibitor lithium chloride (LiCl) confirmed that GSK-3beta inhibition was involved in farrerol-mediated endothelial protection and Nrf2 signaling activation. farrerol glycogen synthase kinase 3 alpha Homo sapiens
5 Further studies performed with GSK-3beta siRNA and specific inhibitor lithium chloride (LiCl) confirmed that GSK-3beta inhibition was involved in farrerol-mediated endothelial protection and Nrf2 signaling activation. farrerol glycogen synthase kinase 3 alpha Homo sapiens
6 Moreover, molecular docking and molecular dynamics studies revealed that farrerol could bind to the ATP pocket of GSK-3beta, which is consistent with the ATP-competitive kinetic behavior. farrerol glycogen synthase kinase 3 alpha Homo sapiens
7 Collectively, our results firstly demonstrate that farrerol could attenuate endothelial oxidative stress by specifically targeting GSK-3beta and further activating the Nrf2-ARE signaling pathway. farrerol glycogen synthase kinase 3 alpha Homo sapiens
