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).
Presence of endothelial nitric oxide synthase (eNOS) gene polymorphism has been associated with cardiovascular disease (CVD) whereas exercise training (EX) promotes beneficial effects on CVD which is related to increased nitric oxide levels (NO).
The eNOS modulatory role of statins may have an imperative influence on the functional regulation of cardiovascular system and may offer new perspectives for the better use of statins in ameliorating cardiovascular disorders.
Taken together, our results show that the 27 nt repeat polymorphism of the intron 4 in the eNOS gene increases susceptibility to cardiovascular diseases after MeHg exposure by modulating nitric oxide levels.
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.
Endothelial nitric oxide synthase (eNOS) gene polymorphisms have been associated with the pathogenesis of cardiovascular diseases, but few studies have evaluated the role of eNOS haplotypes on the risk and prognosis of heart failure (HF).
Cell-based eNOS gene therapy has both proangiogenic and antiatherogenic effects and should be further investigated for the development of efficient therapeutic neovascularization designed to treat ischemic cardiovascular disease.
These data indicate that CAC dysfunction seen in high-risk patients can be partially reversed by eNOS overexpression, suggesting that ex vivo gene delivery may improve the efficacy of autologous cell therapy for cardiovascular disease.
A single nucleotide polymorphism G894T within exon 7 of endothelial nitric oxide synthase (eNOS-7) gene, resulting in a replacement of glutamic acid by aspartic acid, has been studied as a putative candidate gene for cardiovascular diseases.
Thus, our findings revealed a critical function of Akt in mediating genistein-stimulated eNOS activity in PAECs, partially accounting for the beneficial effects of genistein on the development of cardiovascular diseases observed in animal models.
Both the thymidine to cytosine transition mutation (T(-786)-->C) in the promoter region and the missense mutation in the exon 7 coding region of the eNOS gene (G(894)-->T) have been associated with several cardiovascular disease states.
However, the genetic background may also affect NO formation in the cardiovascular system, and recent studies have shown that genetic polymorphisms in the eNOS gene modify endogenous NO formation and the risk of developing cardiovascular diseases.
