lüll IGF-1, oxidative stress and atheroprotection Higashi Y; Sukhanov S; Anwar A; Shai SY; Delafontaine PTrends Endocrinol Metab 2010[Apr]; 21 (4): 245-54Atherosclerosis is a chronic inflammatory disease in which early endothelial dysfunction and subintimal modified lipoprotein deposition progress to complex, advanced lesions that are predisposed to erosion, rupture and thrombosis. Oxidative stress plays a crucial role not only in initial lesion formation but also in lesion progression and destabilization. Although most growth factors are thought to promote vascular smooth muscle cell proliferation and migration, thereby increasing neointima, recent animal studies indicate that insulin-like growth factor (IGF)-1 exerts both pleiotropic anti-oxidant effects and anti-inflammatory effects, which together reduce atherosclerotic burden. This review discusses the effects of IGF-1 in models of vascular injury and atherosclerosis, emphasizing the relationship between oxidative stress and potential atheroprotective actions of IGF-1.|*Oxidative Stress[MESH]|Animals[MESH]|Anti-Inflammatory Agents/*therapeutic use[MESH]|Antioxidants/*therapeutic use[MESH]|Apoptosis[MESH]|Atherosclerosis/*drug therapy/pathology/prevention & control[MESH]|Endothelium, Vascular/cytology[MESH]|Insulin-Like Growth Factor I/metabolism/*therapeutic use[MESH]|Models, Animal[MESH]|Muscle, Smooth, Vascular/pathology[MESH]|Stem Cells/physiology[MESH] |
