Kisspeptin: A Key Regulator in Reproductive Biology Kisspeptin, a neuropeptide encoded by the KISS1 gene, plays a crucial role in regulating reproductive functions through its interaction with the KISS1R receptor. By stimulating gonadotropin-releasing hormone (GnRH) secretion, it drives the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), essential for sexual maturation and fertility. Kisspeptin also exhibits potential as a metastasis suppressor in certain cancers. This pivotal molecule is central to the hypothalamic-pituitary-gonadal axis, making it a critical subject for research in endocrinology and reproductive health.
