The Role of Xanthine Oxidase in Pregnancy Complications: A Systematic Review

Antioxidants
Xanthine oxidoreductase (XOR) is an enzyme involved in the oxidation of hypoxanthine and xanthine to uric acid. XOR has two isoforms: xanthine dehydrogenase and xanthine oxidase (XO).

Increased plasma XOR activity induced by NAFLD/NASH and its possible involvement in vascular neointimal proliferation

JCI Insight, 2021
Xanthine oxidoreductase (XOR) is an enzyme that catalyzes hypoxanthine to xanthine and xanthine to uric acid, respectively. However, the underlying mechanisms of increased plasma XOR and its pathological roles in systemic diseases, such as ...

One Hundred Years of Sulfido Ligand in the Molybdenum Cofactor: New Perspectives

ChemBioChem, Volume 27, Issue 19, 14 October 2026.
The terminal sulfido ligand in mononuclear molybdoenzymes has been appreciated for almost 125 years, with the characterization of Schardinger's enzyme in cow's milk, now known to be xanthine oxidase, that was isolated in 1902 in Vienna, Austria. The ligand is found in molybdoenzymes identified across all kingdoms of life.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, Volume 16, Issue 10, Page 1911-1924, October 2026.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Independent links between plasma xanthine oxidoreductase activity and levels of adipokines

Journal of Diabetes Investigation, 2019
Aims/Introduction Xanthine oxidoreductase (XOR) is a rate‐limiting enzyme that catalyzes uric acid formation in the purine metabolism, is involved in an increase in reactive oxygen species. Plasma XOR activity has been shown to be associated with obesity,

Engineering‐Modulated Molybdenum Enzymes Strategy for Tumor‐Specific Metabolic‐Immunotherapy

Advanced Science, Volume 13, Issue 57, 14 October 2026.
Biodegradable molybdenum sulfide nanoparticles were synthesized via a one‐pot strategy to increase molybdenum enzyme activity and thus effectively potentiate anti‐tumor immunity by integrating molybdenum‐based metalloimmunotherapy with hydrogen sulfide gas therapy.

Plasma xanthine oxidoreductase activity in Japanese patients with type 2 diabetes across hospitalized treatment

Journal of Diabetes Investigation, 2021
Aims/Introduction Xanthine oxidoreductase (XOR) is an enzyme that catalyzes hypoxanthine and xanthine to xanthine and uric acid, respectively. Plasma XOR activity has recently been measured in humans.

Xanthine oxidoreductase is present in human synovium. [PDF]

Annals of the Rheumatic Diseases, 1987
It is postulated that the mobile inflamed joint may be subject to cyclical ischaemic reperfusion injury. Xanthine oxidoreductase is an enzyme thought to contribute to oxidative reperfusion injury, and the detection of this activity in human synovium is described.

Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

Biotechnology and Applied Biochemistry, Volume 73, Issue 5, Page 2189-2201, October 2026.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.
