Hypoxanthine-guanine phosphoribosyltransferase and inosine 5’-monophosphate dehydrogenase activities in three mammalian species: aquatic (Mirounga angustirostris), semiaquatic (Lontra longicaudis annectens) and terrestrial (Sus scrofa)

Frontiers in Physiology, 2015
Aquatic and semiaquatic mammals have the capacity of breath hold (apnea) diving. Northern elephant seals (Mirounga angustirostris) have the ability to perform deep and long duration dives; during a routine dive, adults can hold their breath for 25 min ...

Intrauterine Undernourishment Alters TH1/TH2 Cytokine Balance and Attenuates Lung Allergic Inflammation in Wistar Rats [PDF]

, 2012
IL-4 produced by Th2 cells can block cytokine production by Th1 cells, and Th1 IFN-gamma is known to counterregulate Th2 immune response, inhibiting allergic eosinophilia.

PAK1 inhibitor NVS‐PAK1‐1 preserves dendritic spines in amyloid/tau exposed neurons and 5xFAD mice

Alzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract INTRODUCTION Synaptic spine loss in Alzheimer's disease (AD) contributes to cognitive decline. p21‐activated kinase 1 (PAK1), a regulator of spine integrity, is aberrantly activated in AD. We investigated whether PAK1 inhibition might preserve dendritic spines in vitro and in vivo.

Lesch-Nyhan Syndrome: Evaluation of a Modified Bite Device to Prevent Bite Injuries

Applied Sciences, 2020
Lesch-Nyhan syndrome (LNS) is a serious form of hypoxanthine-guanine phosphoribosyltransferase (HPRT) deficiency, a hereditary purine metabolism disorder. The prevalence reported in the literature is 1/380,000 to 235,000 births.

Efficient gene targeting by homologous recombination in rat embryonic stem cells.

PLoS ONE, 2010
The rat is the preferred experimental animal in many biological studies. With the recent derivation of authentic rat embryonic stem (ES) cells it is now feasible to apply state-of-the art genetic engineering in this species using homologous recombination.

Rat hypoxanthine phosphoribosyltransferase cDNA cloning and sequence analysis

Genomics, 1991
We have determined the nucleotide sequence of the rat hprt (hypoxanthine phosphoribosyltransferase; EC 2.4.2.8.) mRNA coding region and of adjacent, untranslated 5' and 3' mRNA, and we have designed an oligonucleotide primer pair for efficient PCR amplification of the rat hprt coding region.

Exploring Desmin as a Potential Modifier in Duchenne Muscular Dystrophy–Associated Cardiomyopathy

Acta Physiologica, Volume 241, Issue 12, December 2025.
ABSTRACT Aim Duchenne muscular dystrophy (DMD), a rare X‐linked genetic disorder, is affecting skeletal and cardiac muscles due to the loss of the dystrophin protein. Modifier proteins, whose expression is altered in DMD patients, may influence disease progression.

Elevated cortisol concentration in preterm sheep fetuses impacts heart development

Experimental Physiology, Volume 110, Issue 12, Page 1928-1947, December 1, 2025.
Abstract The prepartum rise in cortisol promotes cardiac development and maturation. Here, we investigated the impact of elevated circulating cortisol during mid‐late gestation on cardiac growth and metabolism in fetal sheep. Saline or cortisol (2–3 mg in 4.4 mL/24 h) was infused into the fetal jugular vein from 109 to 116 days gestation (dG, term ...
