Gonadotropin-releasing hormone (GnRH) is released from hypothalamic neurons into the hypophyseal-portal blood system following enzymatic cleavage of the decapeptide from a large precursor (proGnRH) molecule. The purpose of this study was to determine whether the ability of GnRH-producing neurons to ...
In mammals, GnRH is released from nerve endings into the hypophyseal portal system in a pulsatile manner to stimulate the synthesis of the gonadotropes, FSH and LH, from the anterior pituitary. Thus, the communication between the hypothalamic GnRH cells and the pituitary occurs via a localized ...
Gonadotrophin-releasing hormone (GnRH) is produced fromcells in the hypothalamus. It is then released into small blood vessels that carry the hormone to the pituitary gland. As a consequence, the pituitary gland produces luteinizing hormone (LH) and follicle-stimulating (FSH) hormones. What organ ...
GnRH / biochem / abbreviation for gonadotrophin-releasing hormone: a peptide that is released from the brain and stimulates the pituitary gland to secrete gonadotrophic hormones that act in turn on the sex glands Collins English Dictionary - Complete & Unabridged 2012 Digital Edition © William ...
POA. cGnRH-I is released from the median eminence and transported through the hypophysial tract to the anterior pituitary. cGnRH-I plays an important physio- logical role in stimulating the release of gonadotropins, luteinizing hormone (LH), and follicle-stimulating hor- mone (FSH) from the ...
Homologs of GnRH have been identified in invertebrates, including adipokinetic hormone (AKH), corazonin (CRZ) and AKH/CRZ-related peptide (ACP) in arthropods. AKH is a lipid-mobilizing hormone in insects that is released during flight and other energy utilizing activities5. CRZ was discovered on...
When the HPG axis functions correctly, GnRH released by neurons into pituitary portal blood vessels underlying the median eminence of the hypothalamus is carried to the anterior pituitary, where it elicits the secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (...
Glucagon-like peptide (GLP)-1 is a potent glucoregulatory hormone that is released from intestinal L cells into the circulation in response to nutrient ingestion and neural and endocrine stimuli. Structurally, GLP-1 is a 37-amino acid peptide with a MW of 4,2 KDa, having a sequence highly...
Upon response to external cues (such as environmental cues like water temperature) and internal cues, GnRH is released and acts at the pituitary gland to stimulate the synthesis and release of the gonadotropins, which then travel by systemic circulation to the gonads, thereby regulating steroidogenes...
(Luteinizing Hormone Releasing Hormone) is released into the blood and is active on the pituitary gland. (Schally, A. V., A. Arimura, A. J. Kastin (1973). "Hypothalamic regulating hormones." Science 179:341-350.) Here it effects the release of two protein sex hormones, the gonadotropin...
