Stachyose Alleviates Corticosterone-Induced Long-Term Potentiation Impairment via the Gut–Brain Axis

Frontiers in Pharmacology, 2022
Stress can induce learning and memory impairment; corticosterone is often used to study the effects and mechanisms of stress in animal models. Long-term potentiation (LTP) has been widely used for tackling the mechanisms of memory.

The Pivotal Role of GR‐CAR Pathway in Fetal Programming of Hepatic Cytochrome P450 3A Alteration in Adulthood

Advanced Science, EarlyView.
Prenatal dexamethasone exposure (PDE) persistently upregulates hepatic CYP3A1/CYP2B1 in offspring via glucocorticoid receptor (GR) activation. In vivo and in vitro studies show GR promotes P300/CBP binding to the constitutive androstane receptor (CAR) promoter, sustaining histone acetylation (H3K9/K27ac) and enhancing CYP expression. The GR–CAR pathway

Differential Effects of Psychological and Physical Stress on the Sleep Pattern in Rats [PDF]

, 2007
In the present study, we investigated the acute effects of 2 different kinds of stress, namely physical stress (foot shock) and psychological stress (non-foot shock) induced by the communication box method, on the sleep patterns of rats.

Disruption of ovarian function and induction of apoptosis in female mice by Brefeldin A: Mechanistic insights into reproductive toxicity

Animal Models and Experimental Medicine, EarlyView.
Brefeldin A (BFA) significantly inhibits oocyte release and induces apoptosis in ovarian granulosa cells by disrupting follicular development. It downregulates proliferation‐associated genes, reduces SIRT1/SIRT6 proteins, and upregulates cell cycle inhibitors P21 and P16. Additionally, BFA impairs estrogen synthesis and affects ovarian function through

Comparison of Corticosterone Concentrations in Dermal Secretions and Urine in Free-Ranging Marine Toads (Rhinella marina) in Human Care

Veterinary Medicine International, 2023
Corticosterone concentrations have been measured in amphibians by collecting blood or urine samples. However, blood sampling is invasive, and urine can be difficult to collect.

Effect of Edwardsiella ictaluri Infection on Plasma Corticosterone Levels in Channel Catfish (Ictalurus punctatus) [PDF]

, 1984
Channel catfish (Ictalurus punctatus) were innoculated with a new host specific bacterium, Edwardsiella ictaluri, to observe the influence of bacterial infection on plasma corticosterone levels at various temperatures.

The corticotrophin-releasing factor/urocortin system regulates white fat browning in mice through paracrine mechanisms [PDF]

, 2015
Objectives: The corticotrophin-releasing factor (CRF)/urocortin system is expressed in the adipose tissue of mammals, but its functional role in this tissue remains unknown.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Corticosterone rapidly modulates dorsomedial hypothalamus serotonin and behavior in an estrogen- and progesterone-dependent manner in adult female rats: potential role of organic cation transporter 3 (OCT3)

Stress
Previous studies have shown that corticosterone rapidly alters extracellular serotonin (5-hydroxytryptamine; 5-HT) concentrations in the dorsomedial hypothalamus (DMH) of adult male rats, suggesting a role for corticosterone actions in the DMH in ...
