VASOPRESSIN
| Pronunciation (US): |  | (GB): | |
I. (noun)
Sense 1
Meaning:
Hormone secreted by the posterior pituitary gland (trade name Pitressin) and also by nerve endings in the hypothalamus; affects blood pressure by stimulating capillary muscles and reduces urine flow by affecting reabsorption of water by kidney tubules
Synonyms:
ADH; antidiuretic hormone; Pitressin; vasopressin
Classified under:
Hypernyms ("vasopressin" is a kind of...):
pressor; vasoconstrictive; vasoconstrictor (any agent that causes a narrowing of an opening of a blood vessel: cold or stress or nicotine or epinephrine or norepinephrine or angiotensin or vasopressin or certain drugs; maintains or increases blood pressure)
endocrine; hormone; internal secretion (the secretion of an endocrine gland that is transmitted by the blood to the tissue on which it has a specific effect)
Context examples:
An analogue of the hormone vasopressin with antidiuretic and antihemorrhagic properties.
(Desmopressin Acetate, NCI Thesaurus)
This allele, which encodes vasopressin V1b receptor protein, plays a role in adrenocorticotropic hormone regulation.
(AVPR1B wt Allele, NCI Thesaurus)
This, in turn, inhibits the release of various nociceptive neurotransmitters, such as substance P, gamma-aminobutyric acid (GABA), dopamine, acetylcholine, noradrenaline, vasopressin, and somatostatin.
(Dextropropoxyphene Hydrochloride, NCI Thesaurus)
A synthetic octapeptide, and an analogue of human hormone arginine vasopressin with antidiuretic and coagulant activities.
(Desmopressin, NCI Thesaurus)
Demeclocycline also inhibits the effect of vasopressin on the renal tubules, thereby causing diuresis.
(Demeclocycline, NCI Thesaurus)
Other polypeptide ligands of GPCRs include vasopressin, oxytocin, somatostatin, neuropeptide Y, GnRH, luteinizing hormone, follicle stimulating hormone, parathyroid hormone, orexins, urotensin II, endorphins, enkephalins, and many others.
(Bioactive Peptide Signaling Pathway, NCI Thesaurus/BIOCARTA)
This inhibits the release of various nociceptive neurotransmitters, such as substance P, gamma-aminobutyric acid (GABA), dopamine, acetylcholine, noradrenaline, vasopressin, and somatostatin.
(Buprenorphine Transdermal Matrix Patch, NCI Thesaurus)
This agent induces anti-nociception responses mediated through inhibiting the release of various neurotransmitters such as substance P, GABA, dopamine, acetylcholine and noradrenaline; in addition, the release of vasopressin, somatostatin, insulin and glucagon are also inhibited.
(Alfentanil, NCI Thesaurus)
The V2 receptor is expressed in the kidney tubule, predominantly in the distal convoluted tubule and collecting ducts, where its primary property is to respond to the pituitary hormone arginine vasopressin (AVP) by stimulating mechanisms that concentrate the urine and maintain water homeostasis in the organism.
(Arginine Vasopressin Receptor 2, NCI Thesaurus/LocusLink)
In addition, the opening of voltage-gated calcium channels is inhibited, thereby leading to an inhibition of calcium entry and a reduction in the release of various neurotransmitters, including GABA, vasopressin, somatostatin, insulin and glucagons.
(Hydromorphone, NCI Thesaurus)
