Purine metabolism in sprint- vs endurance-trained athletes aged 20‒90 years

open access: yesScientific Reports, 2019
Purine metabolism is crucial for efficient ATP resynthesis during exercise. The aim of this study was to assess the effect of lifelong exercise training on blood purine metabolites in ageing humans at rest and after exhausting exercise.

LRRC4 Orchestrates AP2A1‐Containing Clathrin‐Coated Vesicles to Disrupt Mitochondrial Cristae and Restrict Glioblastoma Progression

open access: yesAdvanced Science, EarlyView.
LRRC4 suppresses GBM by regulating AP2A1‐containing Golgi‐derived clathrin‐coated vesicles. Low LRRC4 allows cytoplasmic AP2A1 to maintain mitochondrial fission‐fusion, MICOS integrity, and OXPHOS, promoting proliferation and invasion. High LRRC4 redirects AP2A1‐containing Golgi‐derived clathrin‐coated vesicles to mitochondria, disrupts MICOS, enhances

Purine Metabolism in Toxoplasma gondii

open access: yesJournal of Biological Chemistry, 1989
We have studied the incorporation and interconversion of purines into nucleotides by freshly isolated Toxoplasma gondii. They did not synthesize nucleotides from formate, glycine, or serine. The purine bases hypoxanthine, xanthine, guanine, and adenine were incorporated at 9.2, 6.2, 5.1, and 4.3 pmol/10(7) cells/h, respectively.

Dual‐Functional Silent‐Region SERS Nanoplatform for Real‐Time Bacterial Tracking and Wound Healing Therapy

open access: yesAdvanced Science, EarlyView.
ABSTRACT Bacterial wound infections, particularly those caused by Escherichia coli and Pseudomonas aeruginosa, are difficult to treat due to biofilm formation, multidrug resistance, and chronic inflammation. Here, we report a multifunctional nanoplatform based on a surface‐enhanced Raman scattering (SERS) probe that enables simultaneous photodynamic ...

Metformin improves HPRT1-targeted purine metabolism and repairs NR4A1-mediated autophagic flux by modulating FoxO1 nucleocytoplasmic shuttling to treat postmenopausal osteoporosis

open access: yesCell Death and Disease
Osteoporosis is a major degenerative metabolic bone disease that threatens the life and health of postmenopausal women. Owing to limitations in detection methods and prevention strategy awareness, the purpose of osteoporosis treatment is more to delay ...

Porcine kidney xenotransplantation: From primate models to clinical reality

open access: yesAnimal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

A member of the gut mycobiota modulates host purine metabolism exacerbating colitis in mice

open access: yesScience Translational Medicine, 2017
Saccharomyces cerevisiae induces purine metabolism in mouse intestinal epithelia, resulting in an exacerbation of colitis. Fungi and inflammatory bowel disease Crohn’s disease is associated with an increase in antibodies against the yeast Saccharomyces ...

Nuclear factor of activated T cells as a driver of tumor progression and a target for precision therapy

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Overview illustration of dysregulated NFAT activation coordinating upstream signaling, post‐translational regulation and cancer promoting pathways to induce abnormal gene expression that drives tumor development, progression and immune escape. Abstract The Nuclear Factor of Activated T Cells (NFAT) family comprises closely related transcription factors.

Complex coordinated extracellular metabolism: Acid phosphatases activate diluted human leukocyte proteins to generate energy flow as NADPH from purine nucleotide ribose

open access: yesRedox Biology, 2016
Complex metabolism is thought to occur exclusively in the crowded intracellular environment. Here we report that diluted enzymes from lysed human leukocytes produce extracellular energy.

Purine metabolism in Echinococcus multilocularis

open access: yesComparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1998
The activities of the enzymes in Echinococcus multilocularis metacestodes involved in purine salvage were studied by HPLC. As in most parasites, this cestode relies entirely on salvage of preformed bases and nucleosides for its purine requirement. Therefore, these enzymes may be targets for drugs in the chemotherapeutic treatment of diseases caused by ...
