Kisspeptin is a 54 amino acid peptide, encoded by the anti-metastasis gene KiSS-1, that activates the G-protein-coupled receptor, GPR54. The kisspeptin/GPR54 system is critical to normal reproductive development. KiSS-1 gene expression is increased in the human placenta in normal and molar pregnancies. Circulating kisspeptin is dramatically increased in normal pregnancy but levels in gestational trophoblastic neoplasia (GTN) have not previously been reported. The...
