Inhibition of lipolysis by oxytocin and vasopressin. 1977

E Fabian, and A Stork, and J Kobilková, and J Fabianová

The administration of 5 I. U. oxytocin (by quick infusion) or of 5 I. U. vasopressin-lysine (intramuscularly) to healthy subjects was followed by a significant decrease in the plasma non-esterified fatty acid level. We regard this as evidence of inhibition of basal lipolysis in the adipose tissue. Vasopressin also completely blocked an increase induced in the plasma non-esterified fatty acid level by activating hormone-sensitive lipase in the adipose tissue by the infusion of 0.5 mg noradrenaline.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
D008053 Lipid Mobilization LIPOLYSIS of stored LIPIDS in the ADIPOSE TISSUE to release FREE FATTY ACIDS. Mobilization of stored lipids is under the regulation of lipolytic signals (CATECHOLAMINES) or anti-lipolytic signals (INSULIN) via their actions on the hormone-sensitive LIPASE. This concept does not include lipid transport. Lipid Mobilizations,Mobilization, Lipid,Mobilizations, Lipid
D010121 Oxytocin A nonapeptide hormone released from the neurohypophysis (PITUITARY GLAND, POSTERIOR). It differs from VASOPRESSIN by two amino acids at residues 3 and 8. Oxytocin acts on SMOOTH MUSCLE CELLS, such as causing UTERINE CONTRACTIONS and MILK EJECTION. Ocytocin,Pitocin,Syntocinon
D005230 Fatty Acids, Nonesterified FATTY ACIDS found in the plasma that are complexed with SERUM ALBUMIN for transport. These fatty acids are not in glycerol ester form.

D014667 Vasopressins Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.
