Corticotropin-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 کاملCorticotropin-releasing hormone links pituitary adrenocorticotropin gene expression and release during adrenal insufficiency.
Corticotropin-releasing hormone (CRH)-deficient (KO) mice provide a unique system to define the role of CRH in regulation of the hypothalamic-pituitary-adrenal (HPA) axis. Despite several manifestations of chronic glucocorticoid insufficiency, basal pituitary proopiomelanocortin (POMC) mRNA, adrenocorticotrophic hormone (ACTH) peptide content within the pituitary, and plasma ACTH concentrations...
متن کاملThyrotropin-releasing Hormone Stimulation of Adrenocorticotropin Production
pituitary tumors in situ, AtT-20/NYU-1 cells were found to produce the alpha subunit of the glycoprotein hormones (alpha). Alpha accumulation in the medium was constant (3.1 ng/mg cell protein per h) and was not affected by TRH. In contrast, TRH increased the amount of ACTH accumulated in the medium from AtT-20/NYU-1 cells to 190 and 420% of control at 1 and 24 h, respectively. TRH induced a do...
متن کاملCorticotropin-releasing hormone in nonhuman primates.
Understanding the many roles that corticotropin-releasing hormone (CRH) plays in facilitating the ordinary and extraordinary events that an individual faces during a lifetime is a complex task, and yet this knowledge is fundamental to understanding our own behaviour and physiology. During the past 25 years, the study of CRH in nonhuman primates, our closest genetic relatives, has grown rapidly....
