Morphology, survival and corticosterone release rates of larval northern leopard frogs throughout chronic NaCl exposure experiment

, 2020
We investigated the influence of increased salinity on survival, growth, water content, and Corticosterone responses of larval Northern Leopard Frogs (Rana pipiens) by exposing them to environmentally-relevant salinity treatments for 24 days.

Heat Stress Promotes Fibroblast‐Derived WNT5A Secretion Through m6A Modification to Activate Melanogenesis

Advanced Science, EarlyView.
Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

Targeting β2‐Adrenergic Receptor Stability With Lycorine Reveals a Host‐Directed Pathway for Antiviral Defense Against Poxviruses

Advanced Science, EarlyView.
Chronic stress drives autophagy‐mediated β2‐AR degradation, impairing antiviral immunity and promoting poxvirus lethality. Lycorine directly stabilizes β2‐AR to restore host defense, suppress excessive inflammation and improve survival. ABSTRACT Psychological stress is a pervasive yet poorly understood modulator of infectious disease outcomes. Here, we

Stress and neurochemical changes associated with chronic alcohol administration [PDF]

, 2001
: There is considerable recent experimental evidence that suggests that stress plays a major role in the development of dependence on drugs of abuse, but the potential mechanisms involved are not yet fully understood.

THE ROLE OF ADRENAL CORTICOSTERONE IN SCHEDULE-INDUCED WHEEL RUNNING

, 1988
In 3 experiments, the role of adrenal corticosterone in schedule-induced wheel running was investigated. Data from the first experiment showed that bilateral adrenalectomy significantly suppressed schedule-induced wheel running, but did not influence ...

Transient Sleep Deprivation Induces Persistent Auditory Neuropathy via ROS‐Initiated Neuroinflammation and BK Channel Suppression

Advanced Science, EarlyView.
Sleep disturbance severity closely tracks hearing loss in a clinical cohort, yet the mechanistic link remains unclear. Acute sleep deprivation is shown to trigger transient cochlear oxidative stress that switches into a self‐sustaining neuroinflammatory state, suppressing BK channels and causing irreversible synaptopathy.

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 ...

A Novel NR3C1 Frameshift Variant Associated With Familial Glucocorticoid Resistance Syndrome: An Integrated Analysis of Steroid Profiling and Structural Modeling

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Glucocorticoid resistance syndrome (GRS) is a rare hereditary disorder caused by pathogenic variants in NR3C1, characterized by marked phenotypic heterogeneity and frequent misdiagnosis as primary aldosteronism or subclinical Cushing's syndrome.

Skin Deep: Cortisol Dominance in Juvenile Lesser Sirens (Siren intermedia) Revealed by Dermal and Water-Borne Glucocorticoid Sampling

Conservation
In vertebrates, corticosterone and cortisol are glucocorticoid (GC) steroid hormones central to the vertebrate stress response, but their relative contribution depends on context and life history.

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

, 2020
We investigated the influence of exposure to chronic salinity (NaCl) and mifepristone (a glucocorticoid antagonist) for 24 d on corticosterone release rates (baseline, stress-induced and corticosterone increase) of Northern Leopard Frogs (Rana pipiens ...
