Oxytocin Receptor OXTR
Oxytocin Receptor OXTR The oxytocin receptor belongs to the G-protein-coupled seven-transmembrane receptor superfamily. Its main physiological role is regulating the contraction of uterine smooth muscle at parturition and the ejection of milk from the lactating breast. The oxytocin receptors are activated in response to binding oxytocin and a similar nonapeptide, vasopressin. Oxytocin receptor triggers Gi or Gq protein-mediated signaling cascades leading to the regulation of a variety of neuroendocrine and cognitive functions. Oxytocin is a nonapeptide of the neurohypophyseal protein family that binds specifically to the oxytocin receptor to produce a multitude of central and peripheral physiological responses. 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 Gq and Gi, stimulate phospholipase C-mediated hydrolysis of phosphoinositides. www.MedChemExpress.com 1 Oxytocin Receptor Agonists & Antagonists Atosiban Atosiban acetate (RW22164; RWJ22164) Cat.

Oxytocin as an appetite suppressant that reduces feeding reward A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Biological Sciences at The University of Waikato by Florence M. Herisson _________ The University of Waikato 2016 2 Abstract In the environment in which palatable and highly caloric foods are readily available, eating behavior is oftentimes not dictated by the necessity to replenish lacking energy, but rather by the pleasure of consumption. Centrally acting oxytocin (OT) is known to promote termination of feeding to protect internal milieu by preventing excessive stomach distension, hyperosmolality and ingestion of toxins. Initial evidence suggests that another possible role for OT in mechanisms governing food intake is to reduce consumption of select palatable tastants. This thesis explores the question whether OT is as an appetite suppressant that reduces feeding reward.

The Oxytocin Receptor: from Intracellular Signaling to Behavior

Neumann Department of Behavioural and Molecular Neurobiology, Institute of Zoology, University of Regensburg, Regensburg, Germany Jurek B, Neumann ID. The Oxytocin Receptor: From Intracellular Signaling to Behav- ior. Physiol Rev 98: 1805–1908, 2018. Published June 13, 2018; doi:10.1152/ physrev.00031.2017.—The many facets of the oxytocin (OXT) system of the brain and periphery elicited nearly 25,000 publications since 1930 (see FIGURE 1, as listed in PubMed), which revealed central roles for OXT and its receptor (OXTR) in reproduction, Land social and emotional behaviors in animal and human studies focusing on mental and physical health and disease. In this review, we discuss the mechanisms of OXT expression and release, expression and binding of the OXTR in brain and periphery, OXTR-coupled signaling cascades, and their involvement in behavioral outcomes to assemble a comprehensive picture of the central and peripheral OXT system. Traditionally known for its role in milk let-down and uterine contraction during labor, OXT also has implications in physiological, and also behavioral, aspects of reproduc- tion, such as sexual and maternal behaviors and pair bonding, but also anxiety, trust, sociability, food intake, or even drug abuse. The many facets of OXT are, on a molecular basis, brought about by a single receptor. The OXTR, a 7-transmembrane G protein-coupled receptor capable of binding ␣ ␣ to either G i or G q proteins, activates a set of signaling cascades, such as the MAPK, PKC, PLC, or CaMK pathways, which converge on transcription factors like CREB or MEF-2.
