Kisspeptin, encoded by Kiss1 gene, has attracted attention as a key neuropeptide in controlling reproduction in mammals. Earlier studies with Kiss1 or its cognate receptor Gpr54 knockout (KO) mice showed the indispensable role of kisspeptin–GPR54 signaling on reproduction, but detailed analysis of gonadotropin release were still limited. Here we have generated Kiss1 KO rats to evaluate a role of kisspeptin on pulsatile gonadotropin secr...
