NO is synthesized from l-arginine through the action of the nitric oxide synthase (NOS) family of enzymes, which includes three isoforms: endothelial NOS (eNOS), neuronal NOS (nNOS) and inducible NOS (iNOS). iNOS-derived NO has been associated with the pathogenesis and progression of several diseases, including liver diseases, insulin resistance, obesity and diseases of the cardiovascular system.
Cytochrome P450 2D6 (CYP2D6) and endothelial nitric oxide synthase (eNOS) are important in the cardiovascular disease susceptibility and drug response.
This approach will allow for a better understanding of the role of eNOS genetic variants in cardiovascular disease progression and for cardiovascular drug therapy optimization.
Asymmetric dimethylarginine (ADMA), an endothelial nitric oxide synthase inhibitor, plays a crucial role in the pathogenesis of various cardiovascular diseases associated with endothelial dysfunction.
We discuss the role of rare NOS3 variants and further gene-gene interactions analysis for the development of novel therapies for cardiovascular diseases.
The risk also holds for the G894T and T-786CeNOS gene polymorphisms when excluding patients with dyslipidemia and cardiovascular diseases (p = 1.7·10<sup>-4</sup> and p = 3.2·10<sup>-5</sup> , respectively).
Another molecule, Sirtuin 1 (SIRT1), a histone/protein deacetylase, regulates endothelial nitric oxide synthase and is involved in different aspects of cardiovascular disease, aging and stress resistance.
With the development of molecular biological technology, the association between genes and diseases has drawn increasing attention of researchers; the endothelial nitric oxide synthase (eNOS) gene has been reported to be a candidate gene for cardiovascular disease (CHD).
These findings indicate that the phosphorylation of eEF1A1 by ROCK2 is physiologically important for eNOS expression and NO-mediated neuroprotection, and suggest that targeting endothelial ROCK2 and eEF1A may have therapeutic benefits in ischemic stroke and cardiovascular disease.
Impaired endothelial function, characterized by an imbalance in endothelial Nitric Oxide Synthase (eNOS) activity, precedes and accelerates the development of CVD.
The results of the present study provide evidence that GLP-1, but not GIP, has a protective effect on endothelial function associated with cardiovascular disease, as it is associated with increased eNOS expression and the levels of NO.
Loss of endothelial BH<sub>4</sub> is observed in cardiovascular disease (CVD) states and results in decreased NO and increased superoxide (O<sub>2</sub><sup>-</sup>) generation via eNOS uncoupling.
In this review, we discuss the basic biochemical mechanisms of NOS3 regulation and the clinical and pharmacogenetic impact of NOS3 polymorphisms on cardiovascular diseases.
We investigated effects of fish-oil supplementation on both classical and novel markers of endothelial function in subjects prospectively genotyped for the Asp298 endothelial nitric oxide synthase (eNOS) polymorphism and at moderate risk of cardiovascular disease (CVD).
Endothelial nitric oxide synthase (eNOS)-uncoupling links obesity-associated insulin resistance and type-II diabetes to the increased incidence of cardiovascular disease.
A single nucleotide polymorphism in the eNOS gene, where thymine (T) replaces guanine (G) at position 894 predicting substitution of glutamate for aspartate at codon 298 (Glu298Asp), has been associated with increased CVD risk due to effects on nitric oxide synthesis and subsequently vascular reactivity.
