| Research Abstract |
We tested our hypothesis that small GTP-binding protein GDP dissociation stimulator (SmgGDS) plays a crucial role in the molecular mechanisms of the Rac1 signaling pathway inhibition by3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors (statins) in endothelial cells. In the present study, we demonstrated that statins exert their pleiotropic effects through SmgGDS upregulation with a resultant Rac1 degradation and reduced oxidative stress in animals and humans.
