摘 要:摘 要:信使RNA 的核苷酸修饰主要包括2'-O- 甲基化、假尿嘧啶化、m6A、m5C、m7G、m1A、5hmC 等。已有的研究表明,这些修饰在mRNA 稳定性、加工、遗传信息传递以及细胞的应激反应中起到重要作用。由于技术的限制,过去我们对于mRNA 修饰知之甚少。近年来,一系列新技术的产生为全面地考察mRNA核苷酸修饰状况,深入地研究它们的生物学功能提供了极大的便利,并且取得了一些重要的进展。就此方面的研究概况作简要概述。
Abstract: Abstract: Nucleotide modifications of messenger RNA include 2'-O-methylation, pseudouridylation, m6A, m5C,m7G, m1A, 5hmC, etc. Previous studies have shown that these modifications play an important role in mRNA stability, processing, transmission of genetic information and cellular stress response. As a result of the limitation oftechnology, we know very little for mRNA modification in the past. Recently, a series of new technology provide great convenience for comprehensive inspection and further biological function research of mRNA nucleotidemodification and have already made some important progress. This review introduced the research progress and prospects of mRNA modification.
