KiSS-1 and reproduction: focus on its role in the metabolic regulation of fertility.
TLDR
Data provide strong evidence for a central role of kisspeptins and GPR54 as molecular conduits for the metabolic regulation of reproductive function – a phenomenon with potential physiopathologic and therapeutic implications.Abstract:
Unraveling of the master role of kisspeptins, the products of the KiSS-1 gene, and their receptor, GPR54, in the control of reproduction has been a major breakthrough in contemporary neuroendocrinology. Indeed, since the disclosure of their reproductive dimension in late 2003, an ever-growing number of genetic, molecular, physiologic and pharmacological studies have defined the crucial role of KiSS-1 neurons as central processors for the dynamic regulation of the gonadotropic axis and its full activation at puberty. Yet, the potential role of the hypothalamic KiSS-1 system as an intermediary factor for the well-known interplay between energy status and reproduction initially received little attention. Recent data, however, strongly suggest a prominent role of KiSS-1 in the metabolic control of fertility, as expression of KiSS-1 gene at the hypothalamus is down-regulated in conditions of negative energy balance and kisspeptin administration is capable of overcoming the hypogonadotropic state observed in undernutrition and disturbed metabolic conditions. Leptin, the adipocyte hormone signaling the size of body energy stores, is likely to play a pivotal role in the metabolic control of the KiSS-1 system, since kisspeptin neurons express leptin receptors and leptin is able to normalize defective KiSS-1 gene expression in models of impaired gonadotropin secretion linked to hypoleptinemia, such as the ob/ob mouse and streptozotocin-induced diabetic rat. In sum, these data provide strong evidence for a central role of kisspeptins and GPR54 as molecular conduits for the metabolic regulation of reproductive function - a phenomenon with potential physiopathologic and therapeutic implications.read more

Neuroendocrinology of reproduction in teleost fish.
TL;DR: Although precise information as to the physiological effects of KiSS1 in fish, notably on GnRH neurons and gonadotropin release, is still limited, KiSS neurons may emerge as the "gatekeeper" of puberty and reproduction in fish as in mammals.

Minireview: kisspeptin/neurokinin B/dynorphin (KNDy) cells of the arcuate nucleus: a central node in the control of gonadotropin-releasing hormone secretion.
TL;DR: Recently, a subset of neurons was identified in the arcuate nucleus of the hypothalamus that colocalize three neuropeptides, kisspeptin, neurokinin B, and dynorphin, each of which has been shown to play a critical role in the central control of reproduction.

Kisspeptins and Reproduction: Physiological Roles and Regulatory Mechanisms
TL;DR: This review aims to provide a comprehensive account of the state-of-the-art in the field of kisspeptin physiology by covering in-depth the consensus knowledge on the major molecular features, biological effects, and mechanisms of action ofkisspeptins in mammals and, to a lesser extent, in nonmammalian vertebrates.

The physiology of obese-hyperglycemic mice [ob/ob mice].
TL;DR: This review summarizes key aspects of what has been learned about the physiology of leptin deficiency as it can be observed in obese-hyperglycemic ob/ob mice, a model for obesity and a rich source of pancreatic islets with high insulin release capacity.

Determinants of menarche.
TL;DR: The aim of this report is to review the recent developments and the current knowledge in the neuroendocrinology of pubertal onset and the factors, genetic and environmental, that influence menarcheal age.

TL;DR: Puberty is initiated when gonadotropin-releasing hormone begins to be secreted by the hypothalamus, and complementary genetic approaches in humans and mice identified genetic factors that determine the onset of puberty.

TL;DR: The present study shows that loss of function of GPR54 is a cause of IHH, and it identifies GPR 54 and possibly KiSS1 protein-derived peptide as playing a major and previously unsuspected role in the physiology of the gonadotropic axis.

TL;DR: Stimulation of oxytocin secretion after kisspeptin administration to rats confirmed this hypothesis that human GPR54 was highly expressed in placenta, pituitary, pancreas, and spinal cord, suggesting a role in the regulation of endocrine function.

TL;DR: It is shown that KiSS-1 encodes a carboxy-terminally amidated peptide with 54 amino-acid residues, which is isolated from human placenta as the endogenous ligand of an orphan G-protein-coupled receptor (hOT7T175) and named ‘metastin’.

TL;DR: GPR54 is defined as a major control point in the reproductive axis and kisspeptin is suggested to be a neurohormonal effector, demonstrating that a key action ofkisspeptin on the hypothalamo-pituitary-gonadal axis occurs directly at the level of GnRH release.
