Oestrogen Induces Rhythmic Expression of the Kisspeptin-1 Receptor GPR54 in Hypothalamic Gonadotrophin-Releasing Hormone-Secreting GT1-7 Cells [PDF]
Journal of Neuroendocrinology, 2011 Oestrogen-stimulated preovulatory gonadotrophin surges are temporally regulated in a way that remains not fully understood. Mammalian ovulation requires surges of gonadotrophin-releasing hormone (GnRH), released from specialised neurones in the hypothalamus. Surge regulation is mediated by ovarian oestrogen (17 β-oestradiol; E(2) ) feedback-acting as a

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.

Bosnian Journal of Basic Medical Sciences, 2019 Polycystic ovary syndrome represents a significant cause of female infertility. The aim of this study was to investigate the expression of anti-Mullerian hormone (AMH), kisspeptin 1 (KISS-1), and kisspeptin 1 receptor (KISS1r) in rat models of polycystic ovary syndrome (PCOS) and controlled ovarian stimulation (COS).

Kisspeptin/GPR54 System: What Do We Know About Its Role in Human Reproduction?
Cellular Physiology and Biochemistry, 2018 Kisspeptin is involved in the control of human reproduction bridging the gap between the sex steroid levels and feedback mechanisms that control the gonadotropin releasing hormone (GnRH) secretion; however, studies considering this peptide and ...
