Metabolic abnormalities and reprogramming in cats with naturally occurring hypertrophic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1256-1270, April 2025.
Abstract Background and aims The heart is a metabolic organ rich in mitochondria. The failing heart reprograms to utilize different energy substrates, which increase its oxygen consumption. These adaptive changes contribute to increased oxidative stress.

Stress response of fire salamander larvae differs between habitat types

Royal Society Open Science
The larvae of the European fire salamander (Salamandra salamandra) can inhabit two different habitats: streams and ponds. Streams are characterized by lower predation risks and higher food availability. Thus, ponds are considered a less suitable habitat.

Epigallocatechin-3-gallate confers protection against corticosterone-induced neuron injuries via restoring extracellular signal-regulated kinase 1/2 and phosphatidylinositol-3 kinase/protein kinase B signaling pathways.

PLoS ONE, 2018
Extensive studies suggested epigallocatechin-3-gallate (EGCG) has significant neuroprotection against multiple central neural injuries, but the underlying mechanisms still remain poorly elucidated.

Corticosterone enhances the potency of ethanol against hippocampal long-term potentiation via local neurosteroid synthesis

Frontiers in Cellular Neuroscience, 2015
Corticosterone is known to accumulate in brain after various stressors including alcohol intoxication. Just as severe alcohol intoxication is typically required to impair memory formation only high concentrations of ethanol (60mM) acutely inhibit long ...

Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Avian Extraembryonic Membranes Respond to Yolk Corticosterone Early in Development [PDF]

During times of maternal stress, developing embryos can be exposed to elevated levels of glucocorticoids which can affect development and permanently alter offspring phenotype.

Offspring Global DNA Methylation is not Affected by Parental Developmental Stress Experience in a Passerine Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Rapid phenotypic change may be mediated by intergenerational transmission of early developmental experiences. In birds, exposure to glucocorticoids during early development can alter global DNA methylation and gene expression. However, DNA methylation is labile, and it is currently unclear whether the impacts of stress suffered during juvenile

Research Note: Quantifying corticosterone in turkey (Meleagris gallopavo) feathers using ELISA

Poultry Science, 2020
The measurement of corticosterone in feathers is an appealing tool for assessing glucocorticoids in wild and domestic bird species. Feather corticosterone measurements can be performed noninvasively and can provide a means for comparing glucocorticoid ...

The Role of Corticosterone Rhythmicity in Puberty [PDF]

Biology of Reproduction, 1976
To establish the functional importance of a peripheral rhythm of corticosterone in the timing of the onset of vaginal opening and ovulation, rats were adrenalectomized at 22 days of age and maintained on either saline or corticosterone (B) dissolved in their drinking water.
