Stress Alters the Discriminative Stimulus and Response Rate Effects of Cocaine Differentially in Lewis and Fischer Inbred Rats

open access: yesBehavioral Science, 2012
Stress enhances the behavioral effects of cocaine, perhaps via hypothalamic-pituitary-adrenal (HPA) axis activity. Yet, compared to Fischer 344 (F344) rats, Lewis rats have hyporesponsive HPA axis function and more readily acquire cocaine self ...

Organ Specificity and Commonality of Epigenetic Aging in Low‐ and High‐Running Capacity Rats

open access: yesAging Cell, Volume 24, Issue 8, August 2025.
Cardiorespiratory fitness (CRF) is not associated with epigenetic clocks, including newly developed ones. On the other hand, CRF is associated with global methylation profiles and promoter methylation in organ‐specific and organ‐common manner. ABSTRACT Epigenetic drift, which is gradual age‐related changes in DNA methylation patterns, plays a ...

Oxidative Stress in People Living With HIV: Are Diverse Supplement Sources the Solution?

open access: yesHealth Science Reports, Volume 8, Issue 5, May 2025.
ABSTRACT Background and Aim Antiretroviral therapy (ART) has reduced human immunodeficiency virus (HIV)/AIDS to a manageable chronic condition even though no cure exists. Despite ART control, latent HIV infection results in failed memory CD4 T‐cell responses, immune overactivation, inflammation, oxidative stress, genomic instability, deoxyribonucleic ...

Photoperiod influences visceral adiposity and the adipose molecular clock independent of temperature in wild‐derived Peromyscus leucopus

open access: yesFASEB BioAdvances, Volume 7, Issue 5, May 2025.
Physiology is closely synchronized to daily and seasonal light/dark cycles. Wild‐derived white‐footed mice were housed in long‐day (LD – 16L:8D) or short‐day (SD – 8L:16D) photoperiods at thermoneutrality (27°C). LD selectively increased visceral WAT mass and decreased Adrβ3 and Ucp1 expression while inducing misalignment of clock genes compared to SD.

Gene-dosage- and sex-dependent differences in the prodromal-Like phase of the F344tgHD rat model for Huntington disease

open access: yesFrontiers in Neuroscience
In Huntington disease (HD) the prodromal phase has been increasingly investigated and is currently in focus for early interventional treatments. Also, the influence of sex on disease progression and severity in patients is under discussion, as a sex ...

Genetic Loci Influencing Cue‐Reactivity in Heterogeneous Stock Rats

open access: yesGenes, Brain and Behavior, Volume 24, Issue 2, April 2025.
A genome‐wide association study characterizing individual differences in cue‐reactivity (sign‐tracking; A) identifies multiple genetic loci, particularly on chromosomes 1 and 18 (B). Multiple candidate genes in these regions were identified, including those with known psychiatric relevance (e.g., Tenm4; C) and novel candidates with heritable ...

Fetal-Adult Cardiac Transcriptome Analysis in Rats with Contrasting Left Ventricular Mass Reveals New Candidates for Cardiac Hypertrophy [PDF]

open access: yes, 2015
Reactivation of fetal gene expression patterns has been implicated in common cardiac diseases in adult life including left ventricular (LV) hypertrophy (LVH) in arterial hypertension.

Risks to human and animal health from the presence of bromide in food and feed

open access: yesEFSA Journal, Volume 23, Issue 1, January 2025.
Abstract The European Commission mandated EFSA to assess the toxicity of bromide, the existing maximum residue levels (MRLs), and possible transfer from feed into food of animal origin. The critical effects of bromide in experimental animals are on the thyroid and central nervous system.

How age, sex and genotype shape the stress response [PDF]

open access: yes, 2016
Exposure to chronic stress is a leading pre-disposing factor for several neuropsychiatric disorders as it often leads to maladaptive responses. The response to stressful events is heterogeneous, underpinning a wide spectrum of distinct changes amongst ...

Re‐evaluation of saccharin and its sodium, potassium and calcium salts (E 954) as food additives

open access: yesEFSA Journal, Volume 22, Issue 11, November 2024.
Abstract This opinion deals with the re‐evaluation of saccharin and its sodium, potassium and calcium salts (E 954) as food additives. Saccharin is the chemically manufactured compound 1,2‐benzisothiazol‐3(2H)‐one‐1,1‐dioxide. Along with its sodium (Na), potassium (K) and calcium (Ca) salts, they are authorised as sweeteners (E 954).
