Research Abstract

We reported that Gab1 is essential for postnatal angiogenesis through the analysis of endothelium-specific Gab1 knockout (Gab1ECKO) mice. However, the role of Gab1 in atherosclerosis remains unknown. We intercrossed Gab1ECKO mice with ApoE knockout (ApoEKO) mice. Six-month-old male ApoEKO/Gab1ECKO and littermate control (ApoEKO) mice were treated with angiotensin II (AngII) via an osmotic infusion minipump. After AngII treatment, ApoEKO/Gab1ECKO mice showed significantly enhanced atherosclerosis and aneurysm formation compared with control mice. The production of proinflammatory cytokines in the aorta was significantly enhanced in ApoEKO/Gab1ECKO mice compared with control. The expression levels of KLF2 and KLF4 were significantly reduced in the aortic endothelium of ApoEKO/Gab1ECKO mice compared with control. Collectively, endothelial Gab1 deletion accelerates AngII-dependent vascular inflammation and atherosclerosis presumably via downregulation of KLF2 and KLF4.
