Regulation of endothelial derived nitric oxide in health and disease.
نویسنده
چکیده
Endothelial nitric oxide synthase (eNOS) is the primary physiological source of nitric oxide (NO) that regulates cardiovascular homeostasis. Historically eNOS has been thought to be a constitutively expressed enzyme regulated by calcium and calmodulin. However, in the last five years it is clear that eNOS activity and NO release can be regulated by post-translational control mechanisms (fatty acid modification and phosphorylation) and protein-protein interactions (with caveolin-1 and heat shock protein 90) that direct impinge upon the duration and magnitude of NO release. This review will summarize this information and apply the post-translational control mechanisms to disease states.

Association between T-786C polymorphism of endothelial nitric oxide synthase gene and level of the vessel dilation factor in patients with coronary artery disease
Various polymorphisms on endothelial nitric oxide synthase (eNOs) gene cause reduced production of NO, the endothelial relaxing factor, and may accelerate the process of atherosclerosis. The study designed to investigate the frequency of T-786C polymorphism of the eNOs gene in patients suffering from coronary artery disease (CAD) in north-west of Iran. One hundred twenty subjects including 60 p...
متن کاملNitric oxide and the bioactivities
Nitric oxide (NO), previously known as Endothelium-Derived Relaxing Factor (EDRF) is involved in a wide range of physiological and pathophysiological mechanisms. It is synthesized endogenously by the enzymes Nitric Oxide Synthase (NOS) in specialized tissues from its precursor L-arginine, yielding L-citrulline as a byproduct. It is released by a family of isoenzymes, viz., the endothelial (eNOS...

Nephrotoxicity of Isosorbide Dinitrate and Cholestasis in Rat: The Possible Role of Nitric Oxide
Background: Nitric oxide (NO), a major chemical form of endothelium-derived relaxing factor and an important regulator of vascular tone, is released by endothelial cells. The role of NO is not restricted to the vascular system, and it participates in the regulation of renal hemodynamics and renal excretory function. There are increasing evidences indicating that the elevated levels of NO play a...
