OBJECTIVE: We previously found a T/C polymorphism in the 5'-flanking region of the endothelial nitric oxide synthase (eNOS) gene and reported that this polymorphism is strongly associated with coronary spasm. In this study, we examined whether the polymorphism is a prognostic marker in coronary spasm patients.

Endothelial nitric-oxide synthase (eNOS) 1 is the enzyme responsible, in major part, for endothelial-derived NO ().Targeted inactivation of the murine eNOS locus by homologous recombination and physiologic assessment of (−/−) off-spring has reinforced the viewpoint that NO in blood vessels plays a quintessential role in regulation of local blood vessel tonus (2, 3), in remodeling of the Cited by: Endothelial nitric oxide synthase: molecular cloning and characterization of a distinct constitutive enzyme isoform.

FPLC and low-temperature SDS–PAGE indicate that the protein is mostly dimeric in both the absence and presence of by: Nitric oxide (NO) is a ubiquitous intercellular messenger molecule synthesized from the amino acid L-arginine by NO synthases in diverse cells and tissues.
NO is synthesized in vascular endothelial cells and appears to play an important role in the control of blood pressure and platelet aggregation. A detailed understanding of the regulation of NO synthesis by endothelial cells has been Cited by: Nitric oxide, a key signaling molecule, is produced by a family of enzymes collectively called nitric oxide synthases (NOS).
Here, we report the crystal structure of the heme domain of endothelial. Recombinant human endothelial nitric-oxide synthase (eNOS) was prepared using a baculovirus expression system as described previously with slight modification (15, 16).

Endothelial dysfunction symbolizes several pathological conditions, including altered anticoagulant and anti-inflammatory properties of the endothelium, impaired modulation of vascular growth, and dysregulation of vascular remodeling. Nevertheless, this term has been used commonly to refer to an impairment of endothelium-dependent vasorelaxation caused by a loss of nitric oxide bioactivity.
Aim: Nitric oxide (NO), produced by the polymorphic endothelial nitric oxide synthase (NOS3), plays an important role in endothelial function. The aim was to determine the effect of NOS3 polymorphisms on hypertension and cardiovascular disease (CVD) in renal allograft by: 7. Nitric oxide (NO) regulates vascular tone and local blood flow, platelet aggregation and adhesion, and leukocyte-endothelial cell interactions.
