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 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...
متن کاملEffects of neurosteroids on the human corticotropin-releasing hormone gene.
Increased activity of hypothalamic-pituitary-adrenal (HPA) axis and hypersecretion of corticotropin-releasing hormone (CRH) are known to be important factors in pathogenesis of some stress-related diseases. Some neurosteroids exert anxiolytic and antidepressant effects probably by inhibition of HPA axis activity. The aim of our study was to find out if neurosteroids can directly affect human CR...
متن کاملCorticotropin-releasing hormone directly activates noradrenergic neurons of the locus ceruleus recorded in vitro.
The neuropeptide corticotropin-releasing hormone (CRH) activates locus ceruleus (LC) neurons, thereby increasing norepinephrine levels throughout the CNS. Despite anatomical and physiological evidence for CRH innervation of the LC, the mechanism of CRH-evoked activation of LC neurons is unknown. Moreover, given the apparent absence of mRNA for CRH receptors in LC neurons, the exact location of ...
