Multiple gonadotropin‐releasing hormone systems in non‐mammalian vertebrates: Ontogeny, anatomy, and physiology

26 Nov 2021

Abstract excerpt

Three paralogous genes for gonadotropin-releasing hormone (GnRH; gnrh1, gnrh2, and gnrh3) and GnRH receptors exist in non-mammalian vertebrates. However, there are some vertebrate species in which one or two of these paralogous genes have become non-functional during evolution. The developmental migration of GnRH neurons in the brain is evolutionarily conserved in mammals, reptiles, birds, amphibians, and jawed...
