Kisspeptins and the neuroendocrine control of reproduction.
Reproductive function, as essential for the survival of species, is under the control of a vast array of regulatory factors that ultimately modulate the release of GnRH. However, GnRH neurons lack the ability to directly sense most of these signals; hence, intermediate pathways are required. Kisspeptins have recently emerged as a pivotal piece in the reproductive brain, serving primarily as con...
متن کاملKisspeptins and reproduction: physiological roles and regulatory mechanisms.
Procreation is essential for survival of species. Not surprisingly, complex neuronal networks have evolved to mediate the diverse internal and external environmental inputs that regulate reproduction in vertebrates. Ultimately, these regulatory factors impinge, directly or indirectly, on a final common pathway, the neurons producing the gonadotropin-releasing hormone (GnRH), which stimulates pi...
متن کاملKisspeptins and RFRP-3 Act in Concert to Synchronize Rodent Reproduction with Seasons
Seasonal mammals use the photoperiodic variation in the nocturnal production of the pineal hormone melatonin to synchronize their reproductive activity with seasons. In rodents, the (SD) short day profile of melatonin secretion has long been proven to inhibit reproductive activity. Lately, we demonstrated that melatonin regulates the expression of the hypothalamic peptides kisspeptins (Kp) and ...
متن کاملKisspeptins: a multifunctional peptide system with a role in reproduction, cancer and the cardiovascular system.
Orphan G-protein-coupled receptors that have recently been paired with their cognate ligand are an often untapped resource for novel drug development. The KISS1 receptor (previously designated GPR54) has been paired with biologically active cleavage peptides of the KiSS-1 gene product, the kisspeptins (KP). The focus of this review is the emerging pharmacology and physiology of the KP. Genetic ...
متن کاملThe role of kisspeptins and GPR54 in the neuroendocrine regulation of reproduction.
Neurons that produce gonadotropin-releasing hormone (GnRH) reside in the basal forebrain and drive reproductive function in mammals. Understanding the circuitry that regulates GnRH neurons is fundamental to comprehending the neuroendocrine control of puberty and reproduction in the adult. This review focuses on a family of neuropeptides encoded by the Kiss1 gene, the kisspeptins, and their cogn...
