摘要 GnRH3 (gonadotropin releasing hormone-3)是促性腺激素释放激素家族成员之一,是鱼类所特有的GnRH类型。鱼类GnRH3具有经典的十肽结构,通过与促性腺激素释放激素受体的结合,在鱼类的性腺发育成熟和感觉调节中起着至关重要的调控作用。本文主要从以下四部分进行了论述,一、GnRH3的结构:其由3个内含子和4个外显子组成,非编码区及内含子与脊椎动物不同,但编码区高度保守;二、鱼类GnRH3的来源:产生于两轮基因组复制事件,最终在鱼类中保留下来;三、GnRH3的产生迁移:嗅区和胚胎外胚层的GnRH3神经元最终迁移到达视前区、腹端脑;四、GnRH3的研究功能进展。本文综述了GnRH3的研究进展,并对未来的发展前景进行展望,旨在为鱼类繁殖调控提供理论依据。

Abstract:Gonadotropin releasing hormone 3 (GnRH3) is a member of the gonadotropin releasing hormone family. GnRH3 has been derived from an earlier genome duplication in an ancestral vertebrate, followed by its loss in the tetrapod lineage,so it has been a unique GnRH type in fish. GnRH3 of fish has a classical decapeptide structure, which plays a crucial regulatory role in maturation of gonads and sensory regulation of fish by binding to gonadotropin releasing hormone receptors. This paper discusses from the following four parts. 1. Structure of GnRH3: It is composed of 3 introns and 4 exons. Non-coding regions and introns are different from vertebrates, but the coding regions are highly conserved; 2. Source of GnRH3: It was generated in two rounds of genome replication events and ultimately reserved in fish; 3. Production and migration of GnRH3: GnRH3 neurons in the olfactory area and the ectoderm of the embryo eventually migrated to the preoptic area and the ventral brain; 4. Research progress of GnRH3. In this paper, the research progress of GnRH3 was reviewed, and the future development prospect was prospected, so as to provide a theoretical basis for the regulation of fish reproduction.
