N6-甲基腺苷(m6 A)是信使RNA上最丰富的修饰,与人类疾病有关,但其在哺乳动物发育中的功能知之甚少。在这里,我们揭示了进化的保守性和功能的m6 A基因在小鼠和人类胚胎干细胞中的甲基化。数以千计的信使和长的非编码RNA显示保守的m6 A修饰,包括编码核心多能性转录因子的转录本。m6 A在定义的序列基序处的3′非翻译区上富集,并且标记不稳定的转录物,包括在分化时翻转的转录物。小鼠和人Mettl 3(m6 A甲基化酶之一)的遗传失活或缺失导致选择靶基因上的m6 A擦除,在分化时延长Nanog表达,并且在体外和体内损害ESC从自我更新向分化成几个谱系的退出。因此,m6 A是干细胞分化为特定谱系所需的转录组灵活性的标志。
N6-methyl-adenosine (m6A) is the most abundant modification on messenger RNAs and is linked to human diseases, but its functions in mammalian development are poorly understood. Here we reveal the evolutionary conservation and function of m6A by mapping the m6A methylome in mouse and human embryonic stem cells. Thousands of messenger and long noncoding RNAs show conserved m6A modification, including transcripts encoding core pluripotency transcription factors. m6A is enriched over 3′ untranslated regions at defined sequence motifs, and marks unstable transcripts, including transcripts turned over upon differentiation. Genetic inactivation or depletion of mouse and human Mettl3, one of the m6A methylases, led to m6A erasure on select target genes, prolonged Nanog expression upon differentiation, and impaired ESC’s exit from self-renewal towards differentiation into several lineages in vitro and in vivo. Thus, m6A is a mark of transcriptome flexibility required for stem cells to differentiate to specific lineages.
