Gonadotropin and kisspeptin gene expression, but not GnRH, are impaired in cFOS deficient mice. [PDF]
, 2015 cFOS is a pleiotropic transcription factor, which binds to the AP1 site in the promoter of target genes. In the pituitary gonadotropes, cFOS mediates induction of FSHβ and GnRH receptor genes.

The Role of the Brain in the Pathogenesis and Physiology of Polycystic Ovary Syndrome (PCOS). [PDF]
, 2019 Polycystic ovary syndrome (PCOS) is a common reproductive endocrine disorder, affecting at least 10% of women of reproductive age. PCOS is typically characterized by the presence of at least two of the three cardinal features of hyperandrogenemia (high ...

Dynamic Kisspeptin Receptor Trafficking Modulates Kisspeptin-Mediated Calcium Signaling [PDF]
Molecular Endocrinology, 2014 Abstract Kisspeptin receptor (KISS1R) signaling plays a critical role in the regulation of reproduction. We investigated the role of kisspeptin-stimulated KISS1R internalization, recycling, and degradation in the modulation of KISS1R signaling.

The Effects of 5-Hydroxytryptamine and Interaction With Kisspeptin in Controlling Ghrelin and Adiponectin Secretion [PDF]
International Journal of Basic Science in Medicine, 2022 Introduction: 5-Hydroxytryptamine (5HT) and kisspeptin are satiety factors, and ghrelin and adiponectin are orexigenic peptides. In this study, the mediating role of 5HT in the effects of GPR54 receptor blocking on ghrelin and adiponectin secretion was ...

Investigating the KNDy hypothesis in humans by co-administration of kisspeptin, neurokinin B and naltrexone in men [PDF]
, 2016 Context: A subpopulation of hypothalamic neurons co-localise three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin collectively termed KNDy neurons. Animal studies suggest they interact to affect pulsatile GnRH release (KNDy hypothesis);

Peripheral and central mechanisms involved in hormonal control of male and female reproduction [PDF]
, 2016 Reproduction involves the integration of hormonal signals acting across multiple systems togenerate a synchronized physiological output. A critical component of reproduction is the luteinizinghormone (LH) surge, which is mediated by estradiol (E2) and ...

Quantification of rat kisspeptin using a novel radioimmunoassay.
PLoS ONE, 2014 Kisspeptin is a hypothalamic peptide hormone that plays a pivotal role in pubertal onset and reproductive function. Previous studies have examined hypothalamic kisspeptin mRNA expression, either through in situ hybridisation or real-time RT-PCR, as a ...

Frontiers in Veterinary Science, 2018 Kisspeptin is a neuropeptide that governs the reproductive axis upstream to GnRH. We wanted to study whether kisspeptin modulates plasma LH and FSH levels and ovarian follicular dynamics in buffaloes and whether kisspeptin can be used for fixed time ...
