Germ-Free Conditions Modulate Host Purine Metabolism, Exacerbating Adenine-Induced Kidney Damage

Toxins, 2020
Alterations in microbiota are known to affect kidney disease conditions. We have previously shown that germ-free conditions exacerbated adenine-induced kidney damage in mice; however, the mechanism by which this occurs has not been elucidated. To explore

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.

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.

Tea and its components reduce the production of uric acid by inhibiting xanthine oxidase

Food & Nutrition Research, 2022
Background: The health benefits of tea are as diverse including the reduction of uric acid levels. Xanthine oxidase is the most directly mediated enzyme in the production of uric acid.

Effect of Natural Polyphenols on Breast Cancer Chemoprevention and Treatment

Molecular Nutrition &Food Research, EarlyView.
Effect of Natural Polyphenols on Breast Cancer proliferation and progression. ABSTRACT Breast cancer is the most common type of malignancy among women worldwide. Significant achievements have been made in diagnostic tools and cancer treatments in the past decade; however, the complexity and heterogeneity of certain breast cancer subtypes often lead to ...

A Xanthine Derivative With Novel Heat Shock Protein 90‐Alpha Inhibitory and Senolytic Properties

Aging Cell, EarlyView.
This study aimed to find safe senolytic drugs that selectively eliminate senescent cells. Focusing on HSP90 inhibitors, we employed a virtual screening to identify novel, safer compounds (A). K5, a xanthinic candidate, effectively eliminated senescent cells in various cellular models (B), extended lifespan in flies, and reduced aging signs in mice (C).

Distribution of xanthine oxidase and xanthine dehydrogenase specificity types among bacteria [PDF]

Journal of Bacteriology, 1977
A diverse collection of xanthine-metabolizing bacteria was examined for xanthine-, 1-methylxanthine-, and 3-methylxanthine-oxidizing activity. Both particulate and soluble fractions of extracts from aerobically grown gram-negative bacteria exhibited oxidation of all three substrates; however, when facultative gram-negative bacteria were grown ...

Targeting Regulation of Macrophage to Treat Metabolic Disease: Role of Phytochemicals

Cell Proliferation, EarlyView.
One‐third of the world's population is affected by metabolic syndrome. Complicated pathogenesis and limited drugs cause the growing prevalence of metabolic syndrome. Macrophage‐mediated metaflammation is closely associated with the development of metabolic syndrome. The role of phytochemicals targeting macrophages in the treatment of metabolic syndrome

The Mechanism of Conversion of Xanthine Dehydrogenase to Xanthine Oxidase

, 1998
Xanthine dehydrogenase and xanthine oxidase are complex metalloflavoproteins that represent alternate forms of the same gene product. The cDNAs encoding the enzymes have been cloned from several sources, and structural information is becoming available.

Stress exposure in the mdx mouse model of Duchenne muscular dystrophy provokes a widespread metabolic response

The FEBS Journal, EarlyView.
A targeted mass spectrometry‐based metabolomics assay was conducted to identify the impact of stress exposure on the regulation of biological stress pathways in the mdx mouse model of Duchenne muscular dystrophy. We demonstrated a broad shift in the circulating stress‐relevant plasma metabolome associated with stressful scruff handling that was ...
