Summary: CRH plays a role in regulating multiple biological systems, and is also associated with reproduction, neuropsychiatric, gastrointestinal, immune disorders, and tumor development. Further research on the physiological functions of CRH will help determine its role in human diseases and may serve as novel therapeutic targets.

Summary: In the neuroendocrine system, corticotropin-releasing hormone (CRH) activates CRHRs and plays a vital role in the HPA/HPI axis. Two CRHR1 subtypes, LcCRHR1-1 and LcCRHR1-2, were identified in Larimichthys crocea genome and were found to be highly homologous to known teleost CRHRs. These receptors were found to be localized in the cell membrane and respond to LcCRH by increasing cAMP, Ca2+ and mitogen-activated protein kinase phosphorylation. LcCRHR1s were expressed in various tissues, with high expression in the brain and ovaries, and shown to be specifically localized in ovarian follicle cells. This study suggests that the CRH/CRHR1 system may be involved in the neuroendocrine regulation of reproduction in L. crocea.

Summary: The study demonstrates that the CRH/CRHR1 system mediates stress-induced hyperactivity, while the temporal activation of cortisol production and associated GR/MR signaling are crucial for prolonging stressor-induced hyperactivity.

Summary: This review focuses on the molecular mechanisms of CRF regulation in the hypothalamus during stress and stress resilience, highlighting the central role of CRF in regulating the stress response. The involvement of ACTH, glucocorticoids, various regulatory factors, and different CRF receptors in stress resilience are discussed.

Summary: Chronic stress is a known risk factor for the development of hypertension. In this study, it was found that the corticotropin-releasing hormone (CRH) neurons in the central nucleus of the amygdala (CeA) are involved in the autonomic responses to chronic stress. Suppressing CeA-CRH neurons can alleviate chronic stress-induced hypertension and decrease elevated sympathetic outflow. Additionally, chronic stress leads to decreased levels of Kv7.2 and Kv7.3 channels in the CeA, which contribute to the hyperactivity of CeA-CRH neurons.

Summary: The study found that intranasal administration of oxytocin had a moderate positive effect size, while intranasal administration of vasopressin had a large negative effect size, and administration of testosterone had no significant impact on cooperative behaviors. Participants with mental dysfunctions were less sensitive to oxytocin and vasopressin administration, and oxytocin administration was effective in in-group situations and for initial choices.

Summary: Insomnia, especially when associated with objective sleep disturbance, was found to be related to activation of the hypothalamic-pituitary-adrenal axis. Men with insomnia demonstrated shorter total sleep time and lower sleep efficiency on polysomnography, as well as lower levels of adrenocorticotropic hormone and cortisol after exposure to stress, suggesting a disrupted hypothalamic-pituitary-adrenal axis function in this population.

Summary: Exercise at an intensity above the lactate threshold leads to an increase in plasma adrenocorticotropic hormone (ACTH), indicating a stress response. This study investigated the involvement of arginine vasopressin (AVP) and corticotropin-releasing hormone (CRH) in regulating exercise-induced ACTH response. Using a rat model, the researchers administered AVP and CRH receptor antagonists and observed a suppression of ACTH levels after exercise. Immunohistochemical evaluation confirmed the activation of AVP and CRH neurons in the hypothalamus. These findings suggest that AVP and CRH cooperatively contribute to exercise-induced ACTH response, reflecting the stress response to moderate-intensity exercise in humans.

Summary: This study reveals the cellular mechanism linking the oxytocin receptor gene mutation (OXTR rs4686302 SNP) with genetic dysregulations associated with autism spectrum disorder (ASD). The mutation leads to increased OXTR protein stability, changes in Ca2+ dynamics, and reduced activation of the MAPK pathway. Whole-genome and RNA sequencing analysis showed numerous differentially regulated genes in the mutant cells, including 429 genes associated with ASD. Computational modeling suggested that the OXTR mutation affects downstream events by altering receptor activation and signaling, consistent with the in vitro results.

Summary: Intracerebroventricular administration of KP-13 induces anxiety-like behavior and activates the HPA axis in rats. The study found that KP-13 alters the AVP and CRF signaling, which may be responsible for its effect on the HPA axis and anxiety-like behavior.

Summary: Our research identified a previously unrecognized ADAMTS1-PTN-Wnt pathway in regulating adipose precursor cell behavior. The non-muscle myosin protein MYH9 was found to be a key target of this pathway for modulating adipogenesis. These findings offer potential for developing novel therapeutics for obesity and related metabolic disorders.
