Endothelial NOS (eNOS), also known as nitric oxide synthase 3 (NOS3) or constitutive NOS (cNOS), is an enzyme that in humans is encoded by the NOS3 gene located in the 7q35-7q36 region of chromosome 7. [5]
Different members of the NOS family are encoded by separate genes. [9] There are three known isoforms in mammals, two are constitutive (cNOS) and the third is inducible (iNOS). [10] Cloning of NOS enzymes indicates that cNOS include both brain constitutive and endothelial constitutive ; the third is the inducible gene. [10]
The neuronal enzyme (NOS-1) and the endothelial isoform (NOS-3) are calcium-dependent and produce low levels of this gas as a cell signaling molecule. The inducible isoform (NOS-2) is calcium-independent and produces large amounts of gas that can be cytotoxic.
Neuronal NOS (NOS1), Endothelial NOS (NOS3), and Inducible NOS macrophage NOS are distinct isoforms. [7] Both the neuronal and the macrophage forms are unusual among oxidative enzymes in requiring several electron donors: flavin adenine dinucleotide (FAD), flavin mononucleotide (FMN), NADPH, and tetrahydrobiopterin.

The Endothelium-derived relaxing factor (EDRF) is a strong vasodilator produced by cardiac endothelial cells in response to stress signals such as high levels of ADP accumulation or hypoxia. [1] Robert F. Furchgott is widely recognised for this discovery, even going so far as to be a co-recipient of the 1998 Nobel Prize in Medicine with his ...
Substrate reduction therapy is FDA approved and there is at least one treatment available on the market. [10] Gene therapy aims to replace a missing protein in the body through the use of vectors, usually viral vectors. [11] In gene therapy, a gene encoding for a certain protein is inserted into a vector. [11]
The glycocalyx also consists of a wide range of enzymes and proteins that regulate leukocyte and thrombocyte adherence, since its principal role in the vasculature is to maintain plasma and vessel-wall homeostasis. These enzymes and proteins include: Endothelial nitric oxide synthase (endothelial NOS) Extracellular superoxide dismutase
2 S therapy reduces myocardial injury and reperfusion complications. [71] [72] Due to its effects similar to NO (without its potential to form peroxides by interacting with superoxide), H 2 S is now recognized as potentially protecting against cardiovascular disease. [69] [73] Recent findings suggest strong cellular crosstalk of NO and H
