Neuromedin U (NMU) and Neuromedin S (NMS) function as putative rregulators of the gonadotropic axis in the rat

Vigo E , Roa J , Castellano JM , Fernandez-Fernandez R , Navarro VM , Pineda R , Aguilar E , Pinilla L , Tena-Sempere M

Neuromedin U (NMU) is a brain-gut peptide originally isolated from porcine spinal cord, and later found in other species. NMU acts through two receptors named NMU1R (abundant in peripheral tissues) and NMU2R (apparently restricted to specific brain regions). Besides its potential implication in the control of stress responses, NMU is abundantly expressed in the ventromedial hypothalamic area and has been involved, as satiety factor, in the regulation of food intake. Very recen...

Gonadotropin responses to kisspeptin are modulated by changes in aminoacidergic and neuropeptidergic neurotransmission: studies in peripubertal male rats

Pineda R , Ruiz-Pino F , Garcia-Galiano D , Sanchez-Garrido M A , Romero M , Castellano J M , Pinilla L , Tena-Sempere M

Introduction: Kisspeptins, the products of the Kiss1 gene that act via the receptor, GPR54 (or Kiss1R), are pivotal elements in the neuroendocrine control of GnRH neurons and, thereby, gonadotropin secretion. Extensive efforts have been devoted recently to elucidate the pharmacological effects and major putative regulators of the kisspeptin system. Yet, our knowledge on the potential interactions of kisspeptins with other key neurotransmitters involved in the central re...

Expression and direct effects of adiponectin in rat testis

Caminos Pinzon JE , Nogueiras R , Gaytan F , Pineda R , Barreiro ML , Gonzalez CR , Castano JP , Malagon MM , Pinilla L , Toppari J , Dieguez C , Tena-Sempere M

The adipose tissue is an active endocrine organ involved in the control not only of metabolism and energy balance, but also of other relevant body functions, including reproduction. Adiponectin is an adipocyte hormone, with relevant roles in lipid metabolism and glucose homeostasis, recently involved in the control of different endocrine organs, such as the placenta, pituitary and, likely, the ovary. However, whether as described previously for other adipokines, such as leptin...

Cellular distribution, regulated expression and functional role of the anorexigenic peptide, NUCB2/nesfatin-1, in the testis

Garcia-Galiano D. , Pineda R. , Ilhan T. , Castellano J. , Ruiz-Pino F. , Sanchez-Garrido M. , Vazquez M. , Sangiao-Alvarellos S. , Romero-Ruiz A. , Pinilla L. , Dieguez C. , Gaytan F. , Tena-Sempere M.

Nesfatin-1, product of the precursor NEFA/nucleobindin 2 (NUCB2), was initially identified as anorectic hypothalamic neuropeptide, acting in a leptin-independent manner. In addition to its central role in the control of energy homeostasis, evidence has mounted recently that nesfatin-1 is also produced in peripheral metabolic tissues, such as pancreas, adipose and gut. Moreover, nesfatin-1 has been shown to participate in the control of body functions gated by whole-body energy...
