Abstract

Nitric oxide (NO) is a gaseous lipophilic free radical generated by three distinct isoforms of nitric oxide synthases (NOS), type 1 or neuronal (nNOS), type 2 or inducible (iNOS) and type 3 or endothelial NOS (eNOS). Expression of eNOS is altered in many types of cardiovascular disease, such as atherosclerosis, diabetes and hypertension. The ubiquitous chaperone heat shock protein 90 (hsp90) associates with NOS and is important for its proper folding and function. Current studies point toward a therapeutic potential by modulating hsp90-NOS association in various vascular diseases. Here we review the transcriptional regulation of endothelial NOS and factors affecting eNOS activity and function, as well as the important vascular pathologies associated with altered NOS function, focusing on the regulatory role of hsp90 and other factors in NO-associated pathogenesis of these diseases.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • NO acts directly on smooth muscle cells via activation of soluble guanylyl cyclase leading to formation of cGMP, which promotes smooth muscle relaxation and inhibits platelet function and vascular smooth muscle cell proliferation and migration.

    “Chiefly, NO acts directly on smooth muscle cells via activation of soluble guanylyl cyclase leading to formation of the second-messenger, cyclic guanosine monophosphate (cGMP), that in turn promotes smooth muscle relaxation and inhibits both platelet function and vascular smooth muscle cell proliferation and migration[19–21].”

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.
