Steroid hormone mediated regulation of corticotropin-releasing hormone gene expression.
Corticotropin-releasing hormone (CRH), a 41 amino acid polypeptide, is expressed in many regions of central nervous system and peripheral tissues and mediates many physiological functions. Abnormal production of CRH is involved in some pathological processes. Among various endogenous factors that modulate CRH production, steroid hormones control CRH production by regulating its gene transcripti...
متن کاملRapid induction of corticotropin-releasing hormone gene transcription in the paraventricular nucleus of the developing rat.
Neonates from postnatal days (pnd) 4-14 display a minimal pituitary-adrenal response to mild stress, the so-called stress hyporesponsive period (SHRP). However, during the SHRP, maternal deprivation (deprived) alters the pituitary-adrenal system, enabling neonates to become endocrine responsive to specific stimuli. Although neonates do display stress-induced ACTH, there is limited evidence for ...
متن کاملDifferential regulation of corticotropin-releasing hormone and vasopressin gene transcription in the hypothalamus by norepinephrine.
All stress-related inputs are conveyed to the hypothalamus via several brain areas and integrated in the parvocellular division of the paraventricular nucleus (PVN) where corticotropin-releasing hormone (CRH) is synthesized. Arginine vasopressin (AVP) is present in both magnocellular and parvocellular divisions of the PVN, and the latter population of AVP is colocalized with CRH. CRH and AVP ar...
متن کاملCorticotropin-releasing hormone physiology
Corticotropin-releasing hormone (CRH), also known as corticotropin-releasing factor, is a highly conserved peptide hormone comprising 41 amino acid residues. Its name derives from its role in the anterior pituitary, where it mediates the release of corticotropin (ACTH) leading to the release of adrenocortical steroids. CRH is the major hypothalamic activator of the hypothalamic–pituitary– adren...
متن کاملCorticotropin-releasing hormone receptors.
Corticotropin-releasing hormone (CRH) and related peptides (urocortins, sauvagine, urotensin) play a central role in the co-ordination of autonomic, behavioural, cardiovascular, immune and endocrine responses to stressful stimuli. Their actions are mediated through activation of two types of G-protein-coupled receptors encoded by separate genes. In this review we focus on the diverse structural...
