Overexpression of ABCG1 Protein Attenuates Arteriosclerosis and Endothelial Dysfunction in Atherosclerotic Rabbits

Overexpression of ABCG1 protein attenuates arteriosclerosis and endothelial dysfunction in atherosclerotic rabbits

The ABCG1 protein is centrally involved in reverse cholesterol transport from the vessel wall. Investigation of the effects of ABCG1 overexpression or knockdown in vivo has produced controversial results and strongly depended on the gene intervention model in which it was studied. Therefore, we investigated the effect of local overexpression of human ABCG1 in a novel model of vessel wall-direct...

Spontaneous Arteriosclerosis in Rabbits

AT(1) receptor antagonism reduces endothelial dysfunction and intimal thickening in atherosclerotic rabbits.

The effects of angiotensin (AT)(1) receptor antagonists on functional and morphological alterations associated with atherosclerosis are not well known. The current study was performed to examine the long-term effects of valsartan (3 or 10 mg/kg per day for 10 weeks) on endothelial function and structural changes in aorta from rabbits fed with either a control diet or a cholesterol-enriched diet...

Xyloketal B Attenuates Atherosclerotic Plaque Formation and Endothelial Dysfunction in Apolipoprotein E Deficient Mice

Our previous studies demonstrated that xyloketal B, a novel marine compound with a unique chemical structure, has strong antioxidant actions and can protect against endothelial injury in different cell types cultured in vitro and model organisms in vivo. The oxidative endothelial dysfunction and decrease in nitric oxide (NO) bioavailability are critical for the development of atherosclerotic le...

Adenosine monophosphate activated protein kinase regulates ABCG1-mediated oxysterol efflux from endothelial cells and protects against hypercholesterolemia-induced endothelial dysfunction.

OBJECTIVE Adenosine monophosphate activated protein kinase (AMPK) has been identified as a regulator of vascular function via the preservation of endothelial cell (EC) function. In this study, we examined whether the beneficial effects of AMPK on ECs are dependent on its involvement in cholesterol efflux and its impact on hypercholesterolemia-induced endothelial dysfunction. METHODS AND RESUL...
