Ovarian 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 receptor 1 expression in the rat endocrine pancreas and evidence suggesting neuromedin U suppressive effect on insulin secretion from isolated rat pancreatic islets.
Neuromedin U (NmU) is a regulatory peptide found in significant concentrations in both the brain and gut of the rat and is named according to its ability to powerfully contract the uterus. Two types of NmU receptors were recently identified and subsequent studies evidenced NmU involvement in the regulation of energy homeostasis. Such a role of neuromedin U suggests that a polypeptide may also b...
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 کاملNeuromedin-U stimulates enucleation-induced adrenocortical regeneration in the rat.
Neuromedin-U (NMU) is a brain-gut peptide, which has been previously found to stimulate hypothalamic-pituitary-adrenal axis in the rat. Enucleation-induced adrenal regeneration in rats with contralateral adrenalectomy is a well-established model of adrenal growth, that not only depends on the compensatory ACTH hypersecretion, but is also modulated by several regulatory peptides. Hence, we inves...
متن کاملCharacterization of neuromedin U effects in canine smooth muscle.
Two endogenous receptors for the potent smooth muscle-stimulating peptide neuromedin U (NmU) have recently been identified and cloned. Pharmacological, binding, and expression studies were conducted in an attempt to determine the receptor(s) involved in the smooth muscle-stimulating effects of NmU. The NmU peptides caused a concentration-dependent contraction of canine isolated urinary bladder....
