摘要:

RNA 表观遗传修饰N6-甲基腺嘌呤(N6-methyladenosine,m6A)是RNA中存在最为广泛的中间化学修饰,普遍存在于生命体中,其中以哺乳动物中的研究最为广泛。m6A修饰酶和结合蛋白的发现证明了RNA甲基化修饰是动态可逆过程,常见的m6A修饰酶主要包括甲基转移酶和去甲基化酶。近年研究陆续发现通过调控m6A在RNA修饰水平上影响mRNA剪切、翻译、稳定性、出核等过程。RNA甲基化介导的表观转录组学参与诸多生物学过程。结合m6A前沿研究成果,对m6A甲基化主要的修饰酶、检测方法及其在胚胎发育、肌肉发育与脂肪生成等方面的生物学功能进行综述,旨为探究m6A甲基化修饰在动物重要的生物学过程中的调控机制寻找新方向。

Abstract:

Epigenetic modification of RNA N6-methyladenine(m6A)is the most extensive intermediate chemical modification in RNA,which exists commonly in living organisms,especially in mammals. The discovery of m6A modifying enzymes and binding proteins confirmed that RNA methylation modification is a dynamic reversible process,and the common m6A modifying enzymes mainly include methyltransferase and demethylase. Recent studies have successively found that m6A modification level and m6A distribution on RNA affect the processes of mRNA splicing,translation,stability,and exporting. RNA methylation-mediated epitranscriptomics is involved in many biological processes. This review summarizes the major m6A methylation modification of enzyme,the detection method and m6A biological functions in embryonic development,muscle development,as well as lipogenesis based on the latest m6A research,aiming to find new directions for exploring the functions and regulatory mechanisms of m6A methylation modification in important biological processes in animals.
