Distribution and regulation of gonadotropin-releasing hormone, kisspeptin, RF-amide related peptide-3, and dynorphin in the bovine hypothalamus [PDF]
PeerJ, 2016 Recent work has led to the hypothesis that kisspeptin/neurokinin B/dynorphin (KNDy) neurons in the arcuate nucleus (ARC) play a key role in gonadotropin-releasing hormone (GnRH) pulse generation and gonadal steroid feedback, with kisspeptin driving GnRH ...

Lower circulating kisspeptin and primary hypogonadism in men with type 2 diabetes
Endocrinology, Diabetes & Metabolism, 2019 Introduction Kisspeptin influence on male androgens is partially understood. We aimed to evaluate serum concentrations of kisspeptin among Ghanaian men with type 2 diabetes and to identify related factors that may contribute to altering circulating ...

Biological Significance of Kisspeptin–Kiss 1 Receptor Signaling in the Habenula of Teleost Species
Frontiers in Endocrinology, 2018 Kisspeptin is a neuropeptide, encoded by kisspeptin 1 (KISS1)/Kiss1 gene, which primarily acts as the regulator of reproductive functions via its receptor, kisspeptin receptor (KissR) in vertebrates.

Kisspeptin: Beyond the Brain [PDF]
Endocrinology, 2015 The hypothalamic-based kisspeptin-signaling system is a major positive regulator of the neuroendocrine-reproductive axis in mammals. During the last decade, major advances have been made in understanding how this signaling system is regulated and how it can be manipulated clinically to achieve beneficial outcomes in treating sex steroid-dependent ...

Frontiers in EndocrinologyBackgroundKisspeptin has been indicated to be a biomarker of fetal growth. Although some evidence suggested that maternal kisspeptin concentrations in early pregnancy were associated with increased fetal growth, studies are still limited and the effect ...

Kisspeptin and seasonality in sheep [PDF]
Peptides, 2009 Sheep are seasonal breeders, experiencing a period of reproductive quiescence during spring and early summer. During the non-breeding period, kisspeptin expression in the arcuate nucleus is markedly reduced. This strongly suggests that the mechanisms that control seasonal changes in reproductive function involve kisspeptin neurons.

Morphine Attenuates Testosterone Response to Central Injection of Kisspeptin in Male Rats [PDF]
International Journal of Fertility and Sterility, 2014 Background Kisspeptin and naloxone stimulate the reproductive axis while morphine inhibits its function. We have investigated the effect of central injection of kisspeptin-10 on mean plasma testosterone concentration in morphine or naloxone pretreated

Reproductive hormone-dependent and -independent contributions to developmental changes in kisspeptin in GnRH-deficient hypogonadal mice. [PDF]
PLoS ONE, 2010 Kisspeptin is a potent activator of GnRH-induced gonadotropin secretion and is a proposed central regulator of pubertal onset. In mice, there is a neuroanatomical separation of two discrete kisspeptin neuronal populations, which are sexually dimorphic ...
