Xanthine oxidoreductase in atherosclerosis pathogenesis: Not only oxidative stress

Abstract

Endothelial xanthine oxidoreductase (XOR) together with NAD(P)H oxidase and nitric oxide (NO) synthase plays a physiologic role in inflammatory signalling, the regulation of NO production and vascular function. The oxidative stress generated by these enzymes may induce endothelial dysfunction, leading to atherosclerosis, cardiovascular diseases and metabolic syndrome. XOR activity creates both oxidant and anti-oxidant products that are implicated in the development of hypertension, smoking vascular injury, dyslipidemia and diabetes, which are the main risk factors of atherosclerosis. In particular, uric acid may have a protective as well as a detrimental role in vascular alterations, thus justifying the multi-directional effects of XOR inhibition. Moreover, XOR products are associated with cell differentiation, leading to adipogenesis and foam cell formation, as well as to the production of monocyte chemoattractant protein-1 from arterial smooth muscle cells, after proliferation and migration. The role of XOR in adipogenesis is also connected with insulin resistance and obesity, two main features of type 2 diabetes.

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.
