Efficacy and Safety of Nanoencapsulated Sirolimus Plus Pegadricase: Results From the Randomized, Placebo‐Controlled Phase 3 Trials

Arthritis &Rheumatology, EarlyView.
Objective DISSOLVE I and II examined the efficacy and safety of nanoencapsulated sirolimus (NAS) plus pegadricase (NASP) in patients with uncontrolled gout (UG). Methods In these double‐blind, placebo‐controlled Phase 3 trials of NASP, patients were randomized 1:1:1 to infusions of high‐dose (HD) or low‐dose (LD) NAS plus pegadricase (HD NASP, LD NASP,

Phosphorylation of Xanthine Dehydrogenase/Oxidase in Hypoxia [PDF]

Journal of Biological Chemistry, 2001
The enzyme xanthine oxidase (XO) has been implicated in the pathogenesis of several disease processes, such as ischemia-reperfusion injury, because of its ability to generate reactive oxygen species. The expression of XO and its precursor xanthine dehydrogenase (XDH) is regulated at pre- and posttranslational levels by agents such as lipopolysaccharide

Discriminating Susceptibility of Xanthine Oxidoreductase Family to Metals

Microbiology Spectrum, 2023
The xanthine oxidoreductase (XOR) family are metal-containing enzymes that use the molybdenum cofactor (Moco), 2Fe-2S clusters, and flavin adenine dinucleotide (FAD) for their catalytic activity.

Heat stress in spermatogenesis: a redox‐dependent decision network linking ROS, autophagy, and regulated cell death

Biological Reviews, EarlyView.
ABSTRACT Heat stress (HS) is an increasing threat to male reproductive health, disrupting spermatogenesis through complex and interdependent cellular responses within the seminiferous epithelium. Although excessive reactive oxygen species (ROS) production is a hallmark of HS, ROS also act as central regulators of cell fate decisions beyond their role ...

Conversion of rat xanthine dehydrogenase to xanthine oxidase during oxidative stress

, 1988
The enzyme “xanthine oxidase” is one of the best characterized sources of superoxide anion and hydrogen peroxide. “in vivo” it mainly acts as a dehydrogenase which, by reducing NAD+, appears to be the physiologic form.

Genetic variants of genes involved in thiopurine metabolism pathway are associated with 6-mercaptopurine toxicity in pediatric acute lymphoblastic leukemia patients from Ethiopia

Frontiers in Pharmacology, 2023
Introduction: Genetic variation in the thiopurine S-methyltransferase (TPMT) gene by and large predicts variability in 6-mercaptopurine (6-MP) related toxicities.

Inherited metabolic epilepsies–established diseases, new approaches

Epilepsia Open, EarlyView.
Abstract Inherited metabolic epilepsies (IMEs) represent the inherited metabolic disorders (IMDs) in which epilepsy is a prevailing component, often determining other neurodevelopmental outcomes associated with the disorder. The different metabolic pathways affected by individual IMEs are the basis of their rarity and heterogeneity.

Vaginal host–microbe signatures linked to placental outcomes in mares

Equine Veterinary Journal, EarlyView.
Abstract Background Ascending placentitis is a leading cause of late‐term pregnancy loss in mares. Although pathogens are presumed to ascend from the caudal reproductive tract, the association between the vaginal microbiome and placentitis has not been systematically examined.

Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.

Catalytic Electrochemistry of Xanthine Dehydrogenase

, 2016
We report the mediated electrocatalytic voltammetry of the molybdoenzyme xanthine dehydrogenase (XDH) from Rhodobacter capsulatus at a thiol-modified Au electrode. The 2-electron acceptor N-methylphenazinium methanesulfonate (phenazine methosulfate, PMS)
