Gatekeeper of GnRH neurons KiSS1R

Loss of function of GPR54 [KiSS-1R] is a cause of IHH, mainly through regulation of GnRH secretion at the hypothalamus. Yet the actual role of the KiSS-1/GPR54 system is-derived peptide metastin supressor of the KiSS1R/GPR54 receptor mutations in KISS1 the system is critical to normal reproductive development, metastasis suppression is not mediated through this receptor though kisspeptins, or mimetics could be used to maintain tumor dormancy. The hypothalamic KiSS-1/GPR54 system has been proven as an essential gatekeeper of GnRH neurons, however interactions (autocrine, paracrine, and/or endocrine) could also impact tumour behaviour in a negative manner.
