Research Article: Oxytocin receptor is regulated by Peg3

Date Published: August 14, 2018 Publisher: Public Library of Science Author(s): Wesley D. Frey, Kaustubh Sharma, Terri L. Cain, Katsuhiko Nishimori, Ryoichi Teruyama, Joomyeong Kim, Osman El-Maarri. http://doi.org/10.1371/journal.pone.0202476 Abstract: Mouse Peg3 encodes a DNA-binding protein involved in the milk letdown process. In the current study, we tested whether PEG3 controls the expression of the oxytocin … Continue reading

Research Article: The Association between Oxytocin and Social Capital

Date Published: December 19, 2012 Publisher: Public Library of Science Author(s): Takeo Fujiwara, Laura D. Kubzansky, Kenji Matsumoto, Ichiro Kawachi, Petter Holme. http://doi.org/10.1371/journal.pone.0052018 Abstract: Oxytocin is known to be related to social behaviors, including trust. However, few studies have investigated the association between oxytocin levels and social capital. Thus, we tested the hypothesis that endogenous oxytocin … Continue reading

Research Article: Oxytocin Signaling in Mouse Taste Buds

Date Published: August 5, 2010 Publisher: Public Library of Science Author(s): Michael S. Sinclair, Isabel Perea-Martinez, Gennady Dvoryanchikov, Masahide Yoshida, Katsuhiko Nishimori, Stephen D. Roper, Nirupa Chaudhari, Hiroaki Matsunami. http://doi.org/10.1371/journal.pone.0011980 Abstract: The neuropeptide, oxytocin (OXT), acts on brain circuits to inhibit food intake. Mutant mice lacking OXT (OXT knockout) overconsume salty and sweet (i.e. sucrose, saccharin) … Continue reading

Research Article: Oxytocin Increases Generosity in Humans

Date Published: November 7, 2007 Publisher: Public Library of Science Author(s): Paul J. Zak, Angela A. Stanton, Sheila Ahmadi, Sarah Brosnan. http://doi.org/10.1371/journal.pone.0001128 Abstract: Human beings routinely help strangers at costs to themselves. Sometimes the help offered is generous—offering more than the other expects. The proximate mechanisms supporting generosity are not well-understood, but several lines of research … Continue reading

Research Article: Oxytocin in the Circadian Timing of Birth

Date Published: September 26, 2007 Publisher: Public Library of Science Author(s): Jeffrey Roizen, Christina E. Luedke, Erik D. Herzog, Louis J. Muglia, Alison Douglas. http://doi.org/10.1371/journal.pone.0000922 Abstract: The molecular components determining the timing for birth remain an incompletely characterized aspect of reproduction, with important conceptual and therapeutic ramifications for management of preterm, post-term and arrested labor. Partial … Continue reading
