The effects of kisspeptin on gonadotropin release in non-human mammals.
Abstract: The Kiss1 gene encodes a 145-amino acid pre-peptide, kisspeptin, which is cleaved into smaller peptides of 54, 14, 13, and 10 amino acids. This chapter reviews in detail the effects of kisspeptin on gonadotropin secretion in non-human mammals. Studies of kisspeptin's effects have included both acute and chronic administration regimens via a number of administration routes. Acute kisspeptin stimulates gonadotropin secretion in a wide range of species of non-human mammals, including rats, mice, hamsters, sheep, pigs, goats, cows, horses, and monkeys. In general, the stimulatory effect of kisspeptin treatment is more pronounced for LH than FSH secretion. Kisspeptin is thought to exert its stimulatory effects on LH and FSH release via stimulation of GnRH release from the hypothalamus, since pre--administration of a GnRH antagonist prevents kisspeptin's stimulation of gonadotropin secretion. Although the kisspeptin receptor is also expressed on anterior pituitary cells of some species, and incubation of anterior pituitary cells with high concentrations of kisspeptin can stimulate in vitro LH release, the contribution of direct effects of kisspeptin on the pituitary is thought to be negligible in vivo. Continuous kisspeptin administration results in reduced sensitivity to the effects of kisspeptin, in some species. This desensitization is thought to occur at the level of the kisspeptin receptor, since the response of the pituitary gland to exogenous GnRH is maintained. Overall, the findings discussed in this chapter are invaluable to the understanding of the reproductive role of kisspeptin and the potential therapeutic uses of kisspeptin for the treatment of fertility disorders.

This research article reviews the impact of a hormone called kisspeptin on the secretion of other hormones that control reproduction in non-human mammals. It particularly focuses on the variations seen in these effects across different species and how kisspeptin interacts with different parts of the endocrine system.
Understanding Kisspeptin
- The Kiss1 gene produces a pre-peptide, named ‘kisspeptin,’ made up of 145 amino acids. This gets broken down into smaller peptides.
- Kisspeptin is a hormone that influences the release of other hormones called gonadotropins, which play a vital role in reproductive processes.
Methodology
- The effects of this hormone were studied both when given acutely – in a single dose – and chronically, over a longer period of time, and through various administration methods.
- The impact of kisspeptin was studied in a wide variety of non-human mammals including rodents, ungulates, and primates.
Key Findings
- Generally, kisspeptin stimulates the release of gonadotropins, impacting the secretion of LH (luteinizing hormone) more significantly than FSH (follicle-stimulating hormone).
- Kisspeptin likely stimulates the release of LH and FSH by triggering the release of another hormone, GnRH (gonadotropin-releasing hormone), from the brain’s hypothalamus. This action is supported by the observation that preventing GnRH release also prevents the stimulation of gonadotropin secretion by kisspeptin.
- The kisspeptin receptor, which kisspeptin binds to stimulate these processes, is found on the cells of the pituitary gland in some species. However, despite these receptors and the fact that high concentrations of kisspeptin can stimulate LH release when directly applied to these pituitary cells, it’s believed this direct interaction plays a negligible role in a live animal’s body.
- One important observation was that the effect of kisspeptin can decrease with continuous administration in some animals due to a process called desensitization. This is thought to happen at the level of the kisspeptin receptor, yet the pituitary gland’s response to external GnRH remains the same.
Significance of the Study and Future Directions
- Overall, these findings provide valuable insights into kisspeptin’s role in reproduction and its potential therapeutic uses in treating fertility disorders.
