RNA调控在精子发生及男性不育中的新功能和新机制

精子发生是哺乳动物体内最复杂且高度协调的细胞发育过程,尚有许多未解之谜.男性不育已成为当前一个全球性的人口健康及社会问题,但一半以上患者病因不明.已有研究证据表明,大量RNA结合蛋白在睾丸特异性表达或高表达,结合蛋白质编码mRNA或/和非编码RNA组成RNA调控网络,在表观遗传、转录及转录后等多重水平调控雄性生殖细胞的基因表达,在精子发生中发挥不可或缺的重要作用,为雄性生育所必需.近年来的研究发现,RNA调控通路相关基因突变与男性不育密切相关,显示RNA调控异常是男性不育新病因.本文总结近期关于RNA调控与精子发生相关的研究进展,将主要概述RNA修饰调控、可变剪接调控、翻译调控、降解调控等在精子发生中的新功能和新机制,并探讨其异常调控与男性不育的相关性及其在男性不育临床诊治中的潜在应用.
New functions and mechanisms of RNA regulation in spermatogenesis and male infertility
Spermatogenesis is the most complicated and highly orchestrated cell development processes in animals,in which many mysteries remain.Male infertility has become a major global concern for population health.Strikingly,more than half of infertile men are of unknown pathologic causes,representing the major challenge in understanding the disease mechanisms.It is evident that a large number of RNA-binding proteins are specifically or highly expressed in testis,forming RNA regulatory networks through binding to the protein-coding mRNAs or/and regulatory non-coding RNAs.Importantly,many RNA-binding proteins and their associated regulatory non-coding RNAs have been shown to regulate gene expression in male germ cells at epigenetic,transcriptional and post-transcriptional levels,playing an indispensable role in spermatogenesis and essential for male fertility.Moreover,genetic mutations in various RNA regulation-related genes have been demonstrated to play causative roles in infertile patients,suggesting abnormal RNA regulation as a new cause of male infertility.In this Review,we summarize the most recent advances in the field,focusing on the new functions and mechanisms of RNA modifications,alternative splicing,translation,degradation in spermatogenesis and male infertility.We also discuss the potential application of RNA regulation in the clinical diagnosis and treatment of male infertility.
