Regulation of endothelial nitric oxide synthase gene expression by oxidized linoleic acid.
Hypercholesterolemia is associated with impairments in endothelium-dependent vascular relaxations. Paradoxically, endothelial production of nitrogen oxides is increased in early stages of hypercholesterolemia. Prior work has shown that oxidized low density lipoprotein (LDL) has both stimulatory and inhibitory effects on endothelial nitric oxide synthase expression (eNOS) and has focused on lyso...
متن کاملEXPRESSION OF INDUCIBLE NITRIC OXIDE SYNTHASE GENE (iNOS) STIMULATED BY HYDROGEN PEROXIDE IN HUMAN ENDOTHELIAL CELLS
Inducible nitric oxide synthase (iNOS) gene expresses a calcium calmudolin-independent enzyme which can catalyse NO production from L-arginine. The induction of iNOS activity has been demonstrated in a wide variety of cell types under stimulation with cytokines and lipopoly saccharide (LPS). Previous studies indicated that all nitric oxide synthases (NOS) activated in human umbilical vein endot...
متن کاملOxidized low density lipoprotein impairs endothelial progenitor cells by regulation of endothelial nitric oxide synthase.
Oxidized low density lipoprotein (OxLDL) is one of the most important risk factors of cardiovascular disease. Here, we study the impact of OxLDL on endothelial progenitor cells (EPCs) and determine whether OxLDL affects EPCs by an inhibitory effect on endothelial nitric oxide synthase (eNOS). It was found that OxLDL decreased EPC survival and impaired its adhesive, migratory, and tube-formation...

متن کاملcGMP-mediated negative-feedback regulation of endothelial nitric oxide synthase expression by nitric oxide.
Earlier studies have demonstrated that nitric oxide (NO) exerts a fast-acting inhibitory influence on endothelial NO synthase (eNOS) enzymatic activity in isolated vascular tissue preparations. The present study was designed to examine the possible effect of NO on eNOS protein expression in cultured endothelial cells and intact animals. Human coronary endothelial cells were incubated with S-nit...
