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

, 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 ...

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

PLoS 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 Asymmetric Dimethylarginine in Psychiatric Disorders [PDF]

Psikiyatride Güncel Yaklaşımlar, 2014
Asymmetric dimethylarginine has been a post-translational modified form of the aminoasid arginine. Being a competitive inhibitor of nitric oxide synthase enzyme, makes asymmetric dimethylarginine important.

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

Antioxidants, 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 ...

Prognostic value of pro-inflammatory markers at the preoperative stage in Algerian women with breast cancer

Forum of Clinical Oncology
Neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), systemic immune-inflammation index (SII), and systemic inflammatory response index (SIRI) are widely used to assess patient’s outcome in many ...

Tetrahydrobiopterin Protects Against Hypertrophic Heart Disease Independent of Myocardial Nitric Oxide Synthase Coupling

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundNitric oxide synthase uncoupling occurs under conditions of oxidative stress modifying the enzyme's function so it generates superoxide rather than nitric oxide.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Inducible nitric oxide synthase links NF-κB to PGE₂ in polyunsaturated fatty acid altered fibroblast in-vitro wound healing

Lipids in Health and Disease, 2005
Background This study investigated mechanisms of altered fibroblast collagen production induced by polyunsaturated fatty acids. 3T3-Swiss fibroblasts were grown in medium containing either eicosapentaenoic or arachidonic acid.

Re‐Purposing Sapropterin (Kuvan) for ACTA2‐Related Multisystemic Smooth Muscle Dysfunction Syndrome: A Translational Mechanistic and First‐In‐Human Therapeutic Report

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Multisystemic smooth muscle dysfunction syndrome (MSMDS) is an ultra‐rare, ACTA2‐related disorder characterized by severe cerebrovascular disease, aortic aneurysms, and smooth muscle dysfunction. Using molecular dynamics simulations and in silico drug screening, we identified that sapropterin dihydrochloride (Kuvan) is a candidate capable of ...
