Background Pre-eclampsia is thought to have an important genetic component. Recently, pre-eclampsia has been associated in some studies with carriage of a common eNOS gene Glu298Asp polymorphism, a variant that leads to the replacement of glutamic acid by aspartic acid at codon 298. Method Healthy women with singleton pregnancies were recruited from 7 district general hospitals in London, UK. W...

one of the most striking features in autosomal dominant polycystic kidney disease (adpkd) is the difference at onset age of end-stage renal disease (esrd). modifier genes may play a role in this phenotypic variability. the mutated nitric oxide synthase 3 gene (nos3), have a modifier effect on the severity of adpkd by impairment of nos3 activity and decreasing of renal vascular nitric oxide prod...

BACKGROUND Altered expression of endothelial nitric oxide synthase (eNOS) has been reported to be involved in the development of endometriosis. The genotypes of eNOS gene (NOS3) may be responsible for variation in its enzymatic activity as well as plasma concentration of nitric oxide. The Glu298Asp polymorphism of the NOS3 may modulate angiogenesis and influence individual susceptibility to end...

A common polymorphism of the endothelial NO synthase gene that predicts a Glu298Asp amino acid substitution in the mature protein has been associated with cardiovascular disorders in which NO bioactivity is impaired. However, the influence of this polymorphism on endothelial function is unknown. Healthy pregnancy is associated with enhanced endothelium-dependent, flow-mediated dilation (FMD) of...

Numerous studies have indicated that the human endothelial nitric oxide synthase (eNOS) gene Glu298Asp polymorphism is associated with coronary heart disease (CHD) susceptibility, however, their conclusions are inconsistent. The present meta‑analysis aimed to evaluate the precise result by searching the PubMed database and using 39 case‑control studies comprising 7489 cases and 7051 controls.Ea...

OBJECTIVES We sought to investigate whether two polymorphisms located in the promoter (T(-786)C) and exon 7 (Glu298Asp) of the endothelial nitric oxide (NO) synthase (eNOS) gene affected agonists-mediated NO release. BACKGROUND Endothelial dysfunction can be genetically determined. Therefore, we investigated whether two polymorphisms located in the eNOS gene affected agonists-mediated NO rele...

PURPOSE Hypertensive response to exercise (HRE) is known to be an adverse prognostic factor for future cardiovascular events and may be associated to endothelial dysfunction. Previous studies regarding endothelial nitric oxide synthase (eNOS) Glu298Asp polymorphism focused upon its relation to hypertension. In this study, we hypothesize that the polymorphism may be associated with inherent diff...

Endothelial nitric oxide synthase gene polymorphism (Glu298Asp) and development of Title: pre-eclampsia: a nested case-control study and a meta-analysis

An endothelial nitric oxide synthase (eNOS) gene polymorphism (Glu298Asp) has been associated with cardiovascular disease. We investigated whether carriage of the polymorphism was associated with functional changes in the endothelium, and how genotype altered the harmful and beneficial impact of environmental influences on the endothelium. Endothelium-dependent, flow-mediated brachial artery di...
