Influence of hyperhomocysteinemia on the cellular redox state - Impact on homocysteine-induced endothelial dysfunction [PDF]

open access: yes, 2003
Hyperhomocysteinemia is an independent risk factor for the development of atherosclerosis. An increasing body of evidence has implicated oxidative stress as being contributory to homocysteines deleterious effects on the vasculature.

Feedback inhibition of nitric oxide synthase activity by nitric oxide [PDF]

open access: yesBritish Journal of Pharmacology, 1993
1. A murine macrophage cell line, J774, expressed nitric oxide (NO) synthase activity in response to interferon-gamma (IFN-gamma, 10 u ml-1) plus lipopolysaccharide (LPS, 10 ng ml-1). The enzyme activity was first detectable 6 h after incubation, peaked at 12 h and became undetectable after 48 h. 2.

Insulin-stimulated phosphorylation of endothelial nitric oxide synthase at serine-615 contributes to nitric oxide synthesis [PDF]

open access: yes, 2009
Insulin stimulates endothelial NO (nitric oxide) synthesis via PKB (protein kinase B)/Akt-mediated phosphorylation and activation of eNOS (endothelial NO synthase) at Ser-1177.

Male gender predisposes to development of endotoxic shock in the rat [PDF]

open access: yes, 2000
Objective: After intravenous (i.v.) injection of lipopolysaccharide (LPS) macrophages release nitric oxide (NO) due to the expression of the inducible NO synthase (iNOS).

Nitric Oxide Synthase and Oxidative Stress: Regulation of Nitric Oxide Synthase

open access: yes, 2012
IntroductionIl a été constaté que l'oxyde nitrique joue un rôle important en tant que molécule signal dans de nombreuses parties de l'organisme ainsi qu'en tant que molécule effectrice cytotoxique de la réponse immunitaire non spécifique.L' oxyde nitrique est une fonction très importante à la fois chez les helminthes et les hôtes mammifères.L' oxyde ...

The key role of nitric oxide in hypoxia: hypoxic vasodilation and energy supply-demand matching [PDF]

open access: yes, 2013
Significance: a mismatch between energy supply and demand induces tissue hypoxia with the potential to cause cell death and organ failure. Whenever arterial oxygen concentration is reduced, increases in blood flow - 'hypoxic vasodilation' - occur in an ...

Postsynaptic α1-Adrenergic vasoconstriction is impaired in young patients with vasovagal syncope and is corrected by nitric oxide synthase inhibition [PDF]

open access: yes, 2016
BACKGROUND: Syncope is a sudden transient loss of consciousness and postural tone with spontaneous recovery; the most common form is vasovagal syncope (VVS).

Elevated exhaled nitric oxide in allergen-provoked asthma is associated with airway epithelial iNOS.

open access: yesPLoS ONE, 2014
BackgroundFractional exhaled nitric oxide is elevated in allergen-provoked asthma. The cellular and molecular source of the elevated fractional exhaled nitric oxide is, however, uncertain.ObjectiveTo investigate whether fractional exhaled nitric oxide is

Role of Dietary Polyphenols in the Activity and Expression of Nitric Oxide Synthases: A Review

open access: yesAntioxidants, 2023
Nitric oxide (NO) plays several key roles in the functionality of an organism, and it is usually released in numerous organs and tissues. There are mainly three isoforms of the enzyme that produce NO starting from the metabolism of arginine, namely ...
