Neopterin and biopterin as biomarkers of immune system activity associated with crating in broiler chickens.

Poultry Science, 2014
Neopterin and biopterin belong to a group of unconjugated pterin derivates. These biomolecules are present in many animal species and perform several functions.

Neopterin as a Tool for Primate Ecoimmunology: Current Knowledge, Practical Application, and New Directions From Captivity to the Wild

American Journal of Primatology, Volume 87, Issue 10, October 2025.
Neopterin is a sensitive and specific biomarker of intracellular pathogen infection and chronic inflammation, and affected by environmental, life‐history, and sex‐contextual factors. This review offers best‐practice guidelines and practical advice on sample collection, storage, and analysis in primates when used for ecoimmunological conservation and ...

Urinary Biopterin Levels and Blood Dihydropteridine Reductase Activities in Patients with Thyroid and Breast Disorders

Pteridines, 2010
Biopterin as a stable metabolite is produced by oxidation of 5,6,7,8-tetrahydrobiopterin (BH4). It is known that many diseases may cause changes in BH4 concentration and/or dihydropteridine reductase (DHPR) enzyme activity. There is only a limited number

Dissecting the genomic regions, candidate genes and pathways using multi‐locus genome‐wide association study for stem rot disease resistance in groundnut

The Plant Genome, Volume 18, Issue 3, September 2025.
Abstract Stem rot, caused by Sclerotium rolfsii Sacc., is a devastating soil‐borne disease causing up to 80% yield losses in groundnut globally. To dissect the genetic basis of resistance, we evaluated a diverse minicore germplasm panel over 3 years in stem rot sick‐field conditions.

Evaluation of dihydropteridine reductase activities in patients with kidney failure

Pteridines, 2013
End-stage renal disease (ESRD) is the inability of the kidneys to remove waste products from the blood. The most important factors causing ESRD that require hemodialysis are diabetes and hypertension.

Comparative Genomics Insights Into the Evolutionary Disparities Between Nitroplast‐Evolved Ecotype UCYN‐A2 and Its Closest Relative UCYN‐A1

Ecology and Evolution, Volume 15, Issue 7, July 2025.
This paper conducted comparative genomic analyses among seven UCYN‐A strains in genome content, gene structure, and key metabolic protein genes. In general, our results demonstrated considerable disparities between UCYN‐A1 and UCYN‐A2, providing insights into the evolution of UCYN‐A and nitroplast.

Biopterin Metabolism and eNOS Expression during Hypoxic Pulmonary Hypertension in Mice

PLoS ONE, 2013
Tetrahydrobiopterin (BH4), which fosters the formation of and stabilizes endothelial NO synthase (eNOS) as an active dimer, tightly regulates eNOS coupling / uncoupling.
