Existence of multiple isoforms of GnRH ligands and receptors in the dwarf gourami, Colisa lalia

Abstract

GnRH (gonadotropin-releasing hormone) plays a pivotal role in the regulation of reproductive functions. We have identified genes encoding three GnRH precursors and three GnRH receptors (GnRHRs) in the dwarf gourami, Colisa lalia. All of their mRNAs were expressed in all the organs examined in the present study. The cloned GnRHR genes were divided into two distinct lineages: types 1 and 2.
