Effect of oxytocin on free intracellular Ca2+ levels and progesterone release by human granulosa-lutein cells [PDF]

open access: yes, 1993
Oxytocin and its receptor are found in the corpus luteum in a variety of species, including the human. In the present study we used fura-2 microfluorimetry to investigate whether activation of the oxytocin receptor of cultured human granulosa-lutein ...

Characterization and Expression of Oxytocin and the Oxytocin Receptor

open access: yesMolecular Genetics and Metabolism, 2000
Oxytocin, a nonapeptide hormone and neurotransmitter, is expressed in a variety of tissues, as are its receptors. In vivo, oxytocin acts as a paracrine and/or autocrine mediator of multiple biological effects. These effects are exerted primarily through interactions with G-protein-coupled oxytocin/vasopressin receptors, which, via G(q) and G(i ...

Oxytocin and Estrogen Receptor β in the Brain: An Overview

open access: yesFrontiers in Endocrinology, 2015
Oxytocin is a neuropeptide synthesized primarily by neurons of the paraventricular and supraoptic nuclei of the hypothalamus. These neurons have axons that project into the posterior pituitary and release oxytocin into the bloodstream to promote labor ...

Elevated salivary levels of oxytocin persist more than seven hours after intranasal administration

open access: yesFrontiers in Neuroscience, 2012
We addressed the question how long salivary oxytocin levels remain elevated after intranasal administration, and whether it makes a difference when 16 IU or 24 IU of oxytocin administration is used.

From autism to eating disorders and more: the role of oxytocin in neuropsychiatric disorders [PDF]

open access: yes, 2016
Oxytocin (oxy) is a pituitary neuropeptide hormone synthesized from the paraventricular and supraoptic nuclei within the hypothalamus. Like other neuropeptides, oxy can modulate a wide range of neurotransmitter and neuromodulator activities. Additionally,

The involvement of actin, calcium channels and exocytosis proteins in somato-dendritic oxytocin and vasopressin release [PDF]

open access: yes, 2012
Hypothalamic magnocellular neurons release vasopressin and oxytocin not only from their axon terminals into the blood, but also from their somata and dendrites into the extracellular space of the brain, and this can be regulated independently ...

Increased Serum and Urinary Oxytocin Concentrations after Nasal Administration in Beagle Dogs

open access: yesFrontiers in Veterinary Science, 2017
In recent years more and more studies have revealed the effect of extraneous oxytocin on the social behavior of dogs. The distribution of administered oxytocin in different physiologically relevant compartments is important because this knowledge forms ...

Association between oxytocin receptor gene polymorphisms and self-rated 'empathic concern' in schizophrenia [PDF]

open access: yes, 2012
The nonapeptide oxytocin (OXT) and its receptor (OXTR) have been implicated in social cognition, empathy, emotion and stress regulation in humans. Previous studies reported associations between OXT and OXTR genetic polymorphisms and risk for disorders ...

Stopping Oxytocin in Active Labor Rather Than Continuing it until Delivery: A Viable Option for the Induction of Labor

open access: yesOman Medical Journal, 2015
Objective: Induction of labor (IOL), using intravenous oxytocin, is the artificial initiation of labor before its spontaneous onset for the purpose of delivery of the fetoplacental unit.
