Electrophilic nitro-fatty acids: anti-inflammatory mediators in the vascular compartment

Open access

Abstract

Vascular inflammatory disorders are often associated with both decreased NO bioavailability and a lack of responsiveness to NO, a consequence of impaired NO biosynthesis, dysregulated l-arginine metabolism, endothelial nitric oxide synthase (eNOS) uncoupling and NO consumption induced by redox reactions of NO. The latter is mediated via oxidative inflammatory conditions altering NO-dependent endothelial function, including vascular tone and cell proliferation. The redox reactions of NO and byproducts such as nitrite can react to yield electrophilic nitro-fatty acid derivatives (NO(2)-FAs) and exemplify a biochemical convergence of reactions participating in NO and lipid signaling. NO(2)-FAs represent a novel therapeutic strategy to treat vascular disorders by improving endothelial dysfunction through enhancing NO signaling and blocking vascular smooth muscle proliferation, inflammation, and maladaptive remodeling.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
