Kisspeptin and GPR54 immunoreactivity in a cohort of 518 patients defines favourable prognosis and clear cell subtype in ovarian carcinoma

BACKGROUND Kisspeptins and their G-protein coupled receptor, GPR54 are required for GnRH release and have been associated with anti-metastatic tumour cell behaviour in model systems. The latter might suggest that their overexpression would be associated with a better prognosis in cancer. However, kisspeptin/GPR54 interactions (autocrine, paracrine, and/or endocrine) could also impact tumour beh...

GPR54 and kisspeptin in reproduction.

Kisspeptins, the peptide products of the KiSS-1 gene, were identified in 2001 as natural ligands of the previously orphan G protein-coupled receptor, GPR54. They include, among others, metastin and kisspeptin-10. The known biological functions of kisspeptins were initially restricted to their ability to suppress tumour metastasis, hence the name of metastin. However, in late 2003, two groups in...
