Pathophysiology of circulating xanthine oxidoreductase: New emerging roles for a multi-tasking enzyme
Open accessAbstract
The enzyme xanthine oxidoreductase (XOR) catalyses the last step of purine degradation in the highest uricotelic primates as a rate-limiting enzyme in nucleic acid catabolism. Although XOR has been studied for more than a century, this enzyme continues to arouse interest because its involvement in many pathological conditions is not completely known. XOR is highly evolutionarily conserved; moreover, its activity is very versatile and tuneable at multiple-levels and generates both oxidant and anti-oxidant products. This review covers the basic information on XOR biology that is essential to understand its enzymatic role in human pathophysiology and provides a comprehensive catalogue of the experimental and human pathologies associated with increased serum XOR levels. The production of radical species by XOR oxidase activity has been intensively studied and evaluated in recent decades in conjunction with the cytotoxic consequences and tissue injuries of various pathological conditions. More recently, a role has emerged for the activity of endothelium-bound enzymes in inducing the vascular response to oxidative stress, which includes the regulation of pro-inflammatory and pro-thrombotic activities of endothelial cells. The possible physiological functions of circulating XOR and the products of its enzyme activity are presented here together with their implications in cardiovascular and metabolic diseases.

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.
