Endothelial nitric oxide synthase gene polymorphisms in giant cell arteritis

Endothelial nitric oxide synthase gene polymorphisms in giant cell arteritis.

OBJECTIVE To examine potential associations of the Glu/Asp(298) polymorphism in exon 7 and the 4a/b polymorphism in intron 4 of the endothelial nitric oxide synthase (eNOS) gene with susceptibility to and clinical expression of giant cell arteritis (GCA), particularly in patients with versus those without ischemic complications. METHODS Ninety-one consecutive patients with biopsy-proven GCA, ...

Endothelial nitric oxide synthase gene polymorphisms and renal survival.

To the Editor: Development of end stage renal disease (ESRD) and a blunted in vitro generation of nitric oxide (NO) have been recently associated with the 298Asp substitution in the endothelial NO synthase (eNOS) gene.1 Diabetic nephropathy was the culprit of ESRD in most patients (pts);1 however, the same association was recently reported in pts with ESRD due to polycystic kidney disease.2 Col...

Computational Prediction of the Effects of Single Nucleotide Polymorphisms of the Gene Encoding Human Endothelial Nitric Oxide Synthase

ABSTRACT           Background and Objective: Genetic variations in the gene encoding endothelial nitric oxide synthase (eNOS) enzyme affect the susceptibility to cardiovascular disease. Identification of the way these changes affect eNOS structure and function in laboratory conditions is difficult and time-consuming. Thus, it seems essential to ...

EXPRESSION 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...
