Hypoxanthine in cerebrospinal fluid in children
Scandinavian Journal of Clinical and Laboratory Investigation, 1978In forty-five children the hypoxanthine concentration in cerebrospinal fluid (CSF) was measured (fifty-two samples). In newborn infants (nineteen patients) the hypoxanthine levels were higher in patients with clinical conditions associated with hypoxia (idiopathic respiratory distress syndrome, asphyxia, apneic attacks) than in patients without ...

A xanthine oxidase (XOD) from buttermilk was immobilized covalently onto boronic acid functionalized gold coated iron nanoparticles (Au@FeNPs) electrodeposited on pencil graphite (PG) electrode, via the boroester linkages, between free hydroxyl groups of boronic acid, α-COOH and -NH2 groups of enzyme.

Plasma Hypoxanthine and Exercise
American Review of Respiratory Disease, 1987Abstract During exercise, ATP is converted to ADP and AMP to supply energy for muscular contraction. It is then regenerated via various pathways of intermediary metabolism. However, with high levels of exercise, net ATP degradation in muscle occurs.

On the interaction of hypoxanthine with adenine
Experientia, 1967Une conversion non-enzymatique d'hypoxanthine en adenine fut proposee sur la base d'observations spectrophotometriques obtenues de solutions contenant adenine et hypoxanthine dans 1–5M de phosphate d'ammonium. Les resultats fournis par les experiences sur la radioactivite ne confirme pas la conclusion emise parBowne2 que hypoxanthine et adenine ...

Hypoxanthine Phosphoribosyltransferase and Hypoxanthine Uptake in Human Erythrocytes
Hoppe-Seyler´s Zeitschrift für physiologische Chemie, 1975A system of hypoxanthine uptake and IMP retention was studied and characterized in human erythrocytes. It follows closely the system already described for rabbit erythrocytes[7]. IMP formation and retention are dependent on the activity of hypoxanthine phosphoribosyl-transferase and on intracellular availability of phosphoribosyl pyrophosphate (P-Rib ...

Biochemical Medicine, 1973
Abstract Hypoxanthine transport has been studied in cultured human fibroblasts with normal and mutant H-G PRT. Transport is dependent on cell density, the activity of H-G PRT, and de novo purine synthesis. Transport is decreased in control cultures at high density and in cell strains with a mutant H-G PRT.

SLC23A3 is a renal hypoxanthine transporter
Nucleosides, Nucleotides & Nucleic Acids, 2022LLC-PK1 renal cells show Na+-dependent and Na+-independent hypoxanthine uptake. While the latter is inhibited by adenine, neither are inhibited by xanthine. In rats, intestinal Na+-dependent hypoxanthine transporter Slc23a4 is not expressed in the kidney, and its action is inhibited by xanthine.
