Oxytocin and Oxytocin Receptors in Cancer Cells and Proliferation
Journal of Neuroendocrinology, 2004AbstractThe hypothalamic nonapeptide oxytocin plays a crucial role in many reproductive and behavioural functions. However, in recent years, an additional new role for oxytocin has been identified in neoplastic pathology. In tumours, oxytocin acts as a growth regulator, through the activation of a specific G‐coupled transmembrane receptor, the oxytocin

The evaluation of a radioimmunoassay of oxytocin is described. The method involved careful collection and transportation of blood at 4 °C, acidification of the plasma, extraction with Fuller's earth and radioimmunoassay using antisera raised in rabbits immunized against oxytocin conjugated to bovine serum albumin and 125I-labelled oxytocin.

Social signals are identified through processing in sensory systems to trigger appropriate behavioral responses. Social signals are received primarily in most mammals through the olfactory system. Individuals are recognized based on their unique blend of odorants.

The oxytocin receptor was first identified using a pharmacological ligandbinding assay in the rat myometrium (Soloff and Swartz 1973). Its peptide ligand, oxytocin, belongs to the nonapeptide hormone family comprising both oxytocin-like (mesotocin, isotocin, etc.) and vasopressin-like (vasotocin, phenypressin, etc.) cyclic peptides.

Oxytocin has potent central effects on feeding behaviour, as well as on social and sexual behaviours, and one likely substrate for its anorectic effect is the ventromedial nucleus of the hypothalamus. This nucleus expresses a high density of oxytocin receptors, but contains very few oxytocin-containing fibres, hence it is a likely target of ...

Testicular oxytocin: effects of intratesticular oxytocin in the rat
Journal of Endocrinology, 1991ABSTRACT The long-term effects of oxytocin administration on the testis were studied using intratesticular implants. Adult male rats had an Accurel device containing 20 μg oxytocin (releasing approximately 200 ng/day) implanted into the parenchyma of each testis; control animals received empty devices.

Determination of oxytocin in milk of cows administered oxytocin
Analytica Chimica Acta, 2009To address people's concerns of exogenous oxytocin (OT) administration to lactating bovines, a study was undertaken to (a) establish an enzyme immunoassay (EIA) for OT determination in milk, (b) quantify OT in milk of cows administered OT, and (c) study influence of pasteurization on OT stability in milk.

Oxytocin and Oxytocin Receptor Gene Expression in the Uterus
1995Publisher Summary The posterior pituitary contains a strong uterotonic activity known as the nonapeptide oxytocin (OT). It has been determined that uterus itself represents a major site of OT production. Therefore, the activation of uterine contractions by circulating OT is only one aspect of OT action. A significant portion of OT activity originates

Oxytocin is an endogenous cyclic nonapeptide that is synthesized in the paraventricular and supraoptic nuclei of the hypothalamus. It is stored in the posterior pituitary before release. Oxytocin stimulates the uterus, particularly in the later stages of pregnancy and induces milk ejection during lactation.
