摘要:

甲状腺激素(thyroid hormone,TH)及其受体除了参与调控机体正常发育和代谢平衡外,还在动物繁殖活动中发挥重要的生物学作用。甲状腺激素受体α(thyroid hormone receptor alpha,TRα)和甲状腺激素受体β(thyroid hormone receptor beta,TRβ)属于配体依赖性核受体超家族成员,分别由THRATHRB两个基因编码,这两个基因的选择性剪接或转录起始位置不同可导致不同组织中存在多种受体亚型。本文首先介绍了TRs的基本特征;然后以下丘脑-垂体-性腺轴(hypothalamic-pituitary-gonadal axis,HPGA)为主线,综述了TRs通过参与促性腺激素释放激素(gonadotropin-releasing hormone,GnRH)脉冲释放、促性腺激素水平、促性腺激素受体和性激素受体的表达实现对性腺轴系统的繁殖调控;最后,从TH-GnRH通路、TH/TRs在哺乳动物季节性繁殖中的作用及在鸟类季节性繁殖中的作用3个方面概述了TH/TRs对动物季节性繁殖的调控作用,有助于深入了解动物季节性繁殖的分子机制,为季节性发情的人工调控提供新思路。

Abstract:

Thyroid hormone (TH) and its receptors play an important biological role in animal reproduction, in addition to regulating normal body development and metabolic balance. Thyroid hormone receptor alpha (TRα) and thyroid hormone receptor beta (TRβ) belong to the ligand-dependent nuclear receptor superfamily and are encoded by the THRA and THRB genes, respectively. Different alternative splicing or transcription start positions in the 2 genes can result in multiple receptor subtypes in different tissues. In this review, the basic characteristics of TRs were introduced firstly. Then using the hypothalamic-pituitary-gonadal axis (HPGA) as a clue, the regulation of TRs on the gonadal axis system by involving pulse release of gonadotropin-releasing hormone (GnRH), levels of gonadal hormones, gonadotropin receptor and sex hormone receptor expression was reviewed. Finally, this review summarizes the regulation of TH/TRs on seasonal reproduction from aspects of TH-GnRH pathway, the role of TH/TRs in seasonal reproduction of mammals and their role in seasonal bird reproduction in favor of understanding the molecular mechanism of seasonal reproduction of animals and providing new ideas for artificial regulation of seasonal estrus.
