Comparison of feeding suppression by the anorexigenic hormones neuromedin U and neuromedin S in rats.
We compared the central mechanisms of feeding suppression by the anorexigenic hormones neuromedin U (NMU) and neuromedin S (NMS) in rats. I.c.v. injection of either NMU or NMS dose dependently decreased 3-h food intake during the first quarter of a dark period. Pretreatment involving i.c.v. injection of a specific anti-NMS IgG blocked the suppression of food intake induced by i.c.v.- and i.p.-i...
متن کاملHypothalamic actions of neuromedin U.
The central nervous system and gut peptide neuromedin U (NMU) inhibits feeding after intracerebroventricular injection. This study explored the hypothalamic actions of NMU on feeding and the hypothalamo-pituitary-adrenal axis. Intraparaventricular nucleus (intra-PVN) NMU dose-dependently inhibited food intake, with a minimum effective dose of 0.1 nmol and a robust effect at 0.3 nmol. Feeding in...
متن کاملOvarian regulation of neuromedin U and its local actions in the ovary, mediated through neuromedin U receptor 2.
Neuromedin U (NMU) was originally identified as an anorexigenic peptide that modulates appetite as well as energy homeostasis through the brain-gut axis. Although growing evidence has linked NMU activity with the development of female reproductive organs, no direct expression of and function for NMU in these organs has been pinpointed. Using a superovulated rat model, we found that NMU is direc...
متن کاملNeuromedin U and its receptors: structure, function, and physiological roles.
Neuromedin U (NmU) is a structurally highly conserved neuropeptide. It is ubiquitously distributed, with highest levels found in the gastrointestinal tract and pituitary. Originally isolated from porcine spinal cord, it has since been isolated and sequenced from several species. Amino acid alignment of NmU from different species reveals a high level of conservation, and particular features with...
متن کاملNeuromedin U and Its Putative Drosophila Homolog hugin
Christoph Melcher, Rüdiger Bader, Steffen Walther, Oleg Simakov, Michael J. Pankratz We recently provided a molecular, neuroanatomical, and behavioral analyses of neurons expressing the neuropeptide gene hugin in Drosophila [1]. hugin-expressing neurons appear to comprise a neural circuitry in the brain that modulates feeding behavior in response to gustatory and nutrient signals. One of the qu...
