Xanthine oxidoreductase and xanthine oxidase in human cornea.

Histology and histopathology, 2002
Xanthine oxidoreductase (xanthine dehydrogenase + xanthine oxidase) is a complex enzyme that catalyzes the oxidation of hypoxanthine to xanthine, subsequently producing uric acid. The enzyme complex exists in separate but interconvertible forms, xanthine dehydrogenase and xanthine oxidase, which generate reactive oxygen species (ROS), a well known ...

The role of urate and xanthine oxidase in vascular oxidative stress:Future directions [PDF]

, 2009
Vascular oxidative stress has been shown to be a potent factor in the pathophysiology of endothelial dysfunction. Despite current optimal evidence-based therapy, mortality from various cardiovascular disorders remains high.

Reductive activation of potential antitumor bis(aziridinyl)benzoquinones by xanthine oxidase: Competition between oxygen reduction and quinone reduction [PDF]

, 1990
The reduction of a series of 2,5-bis(1-aziridinyl)-1,4-benzoquinone (BABQ) derivatives with various 3,6 substituents by the enzyme xanthine oxidase has been studied.

Genetic predisposition to porto‐sinusoidal vascular disorder: A functional genomic‐based, multigenerational family study

Hepatology, EarlyView., 2022
A deleterious variant of FCHSD1 results in mTOR pathway overactivation and may cause porto‐sinusoidal vascular disorder (PSVD). The pedigree of the family demonstrated an autosomal dominant disease with variable expressivity. Whole‐genome sequencing and Sanger sequencing both validated the existence of the FCHSD1 variant and the heterozygosity of c ...

Reduction of leukocyte microvascular adherence and preservation of blood-brain barrier function by superoxide-lowering therapies in a piglet model of neonatal asphyxia [PDF]

, 2019
Background: Asphyxia is the most common cause of brain damage in newborns. Substantial evidence indicates that leukocyte recruitment in the cerebral vasculature during asphyxia contributes to this damage. We tested the hypothesis that superoxide radical (

Search of protein kinase CK2 inhibitors based on purine-2,6-diones derivatives [PDF]

The Ukrainian Biochemical Journal, 2017
This work is aimed to the search of protein kinase CK2 inhibitors among the purine-2,6-dione derivatives by molecular docking and biochemical tests. It was found that the most active compound 8-[2-[(3-methoxyphenyl)methylidene]hydrazine-1-yl]-3-methyl-7-(

Absence of xanthine oxidase or xanthine dehydrogenase in the rabbit myocardium [PDF]

Biochemical and Biophysical Research Communications, 1986
We directly measured the activity of the enzymes xanthine oxidase and xanthine dehydrogenase in rabbit and rat hearts, using a sensitive radiochemical assay. Neither xanthine oxidase activity nor xanthine dehydrogenase activity was detected in the rabbit heart.

The Role of Xanthine Oxidase and Xanthine Dehydrogenase in Skin Ischemia [PDF]

Journal of Surgical Research, 1994
The importance of sequential events which lead to skin necrosis has significant implications in trauma, vascular injury, and wound healing. In this series of experiments, we tested the hypothesis that xanthine oxidase (XO) activity was increased along an ischemic gradient of a skin flap and that the XO enzyme activity correlated with an increase in ...
