Bringing the Lab to the Field: Exploring Water‐Borne Corticosterone as a Physiological Indicator in Captive and Wild Common Frog Larvae (Rana temporaria)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Assessing physiological condition in wild populations is important for understanding how environmental variation shapes organismal performance. Water‐borne corticosterone (WB‐CORT) sampling shows promise for studying amphibian stress physiology, but its ecological relevance and limitations require evaluation, particularly when methods ...

Acute and chronic glucocorticoid treatments regulate astrocyte-enriched mRNAs in multiple brain regions in vivo

Frontiers in Neuroscience, 2013
Previous studies have primarily interpreted gene expression regulation by glucocorticoids in the brain in terms of impact on neurons; however, less is known about the corresponding impact of glucocorticoids on glia and specifically astrocytes in vivo ...

Corticosterone destabilizes newly formed endothelial cell sprouts.

, 2012
Skeletal muscle endothelial cell spheroids were suspended in a 3-dimensional type I collagen culture. Spheroids were treated for 24 and 48 hours with 600 nM corticosterone.

Survival and mean corticosterone release rates of larval northern leopard frogs (Rana pipiens) per day throughout chronic NaCl exposure experiment

, 2020
We investigated the influence of corticosterone release rates on survival of larval Northern Leopard Frogs (Rana pipiens) chronically exposed to four different concentrations of salinity (NaCl). The dataset contains mean values for snout-vent length (mm),

Sex‐Specific Early Life Corticosterone Stress‐Coping Capacity Is Linked to Mitochondrial Content and Telomere Maintenance

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Glucocorticoids are upregulated during acute challenges, contributing to maintenance of energy balance. However, if this upregulation exceeds a threshold or becomes chronic, it can lead to harmful effects. Investigating the factors behind between‐individual variation in the magnitude of the response to acute stress and how effectively ...

Corticosterone Induces Depressive-Like Behavior in Female Peri-Pubescent Rats, but Not in Pre-Pubescent Rats

Chronic Stress, 2020
Background There are no data on the effect of exogenous corticosterone on depressive-like behavior in juvenile rats. Furthermore, it has not been tested whether the effects of corticosterone in female rats is different before or after puberty.

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Corticosterone reinforces motivation for drug-seeking in morphine-dependent rats in Morris maze performance

, 2000
Corticosterone and morphine's effect on motivational intensity for drug-seeking was investigated. Rats were given intraperitoneal injections with morphine, corticosterone, morphine plus corticosterone immediately after trained without platform.

Plasma Steroid Trajectories From Day‐of‐Surgery Baseline After Robot‐Assisted Radical Prostatectomy for Prostate Cancer

The Prostate, EarlyView.
ABSTRACT Background Circulating steroid trajectories after robot‐assisted radical prostatectomy are poorly characterized from the day‐of‐surgery baseline, and relevant biology extends beyond testosterone and dihydrotestosterone to adrenal‐derived 11‐oxygenated androgens and steroid conjugate turnover.
