重要学术研究成果与贡献
m6A RNA甲基化是在mRNA和lincRNA中广泛存在并且可以被去甲基化酶清除的RNA修饰,在哺乳动物中,超过7000个蛋白质编码基因所转录的mRNA含有m6A甲基化修饰,然而这些m6A修饰的功能并不十分清楚。本人与合作者通过对哺乳动物胚胎干细胞的m6A组学以及功能研究发现m6A在胚胎干细胞中动态变化并且在干细胞分化中发挥了关键作用 (Cell Stem Cell, 2014)。为了系统鉴定在细胞命运决定中发挥关键作用的m6A位点,利用ABE单碱基编辑开发转录组水平的m6A位点功能筛选技术,系统鉴定了在人胚胎干细胞向内胚层分化过程中发挥关键作用的m6A位点。(Nature Communications, 2022)
由于m6A的动态变化主要表现为甲基化程度的变化,而现有的技术都不能在基因组水平对m6A进行精确和绝对定量,也没有技术能够区分m6A发生在哪些特定的转录本异构体(isoform)上,技术上的欠缺严重阻碍了该领域的继续发展。本人与合作者通过对已有的m6A-seq技术的改进发明了第一种能够对m6A进行全基因组精确和绝对定量的方法(m6A-LAIC-seq)。我们通过新技术首次发现m6A广泛发生于使用近端Poly(A)加尾信号的mRNA上,m6A的这种全新的模式使得它能够与miRNA和RNA结合蛋白协同作用从而更加精细地对RNA进行转录后调控(Nature Methods, 2016)。
为了进一步揭示m6A动态变化的机理,建立了一套基于m6A共甲基化网络的计算框架来系统地鉴定细胞特异的m6A反式调控因子。通过对目前公开的25个不同的细胞系的104个m6A-seq、上百个RNA结合蛋白的CLIP-seq数据和识别序列的系统性整合最终鉴定出32个特异性调控m6A的RNA结合蛋白。并对3个HepG2细胞系特异的m6A的调控因子中的两个成功进行了实验验证。揭示了大量RNA结合蛋白很可能通过特异性调控m6A参与建立细胞特异的m6A甲基化模式 (Nucleic Acids Research, 2020)。并详细研究了其中一个RNA 结合蛋白SRSF7,发现它通过特异性调控m6A促进胶质瘤的进展。(Genomics, Proteomics & Bioinformatics,2022)
为了回答相同细胞的不同基因如何形成特异性的m6A修饰,利用上述开发的m6A-LAIC-seq m6A定量技术比较假基因和同源的蛋白编码基因的m6A水平,发现假基因的m6A水平远高于同源的蛋白编码基因。进一步揭示加工型假基因在进化过程中在达尔文正向选择的驱动下快速积累产生m6A motif 的突变,从而造成加工型假基因的m6A水平显著高于同源的蛋白编码基因,进化出利用m6A降解加工型假基因的方式。这些进化出的m6A位点对于降解加工型假基因防止其通过ceRNA的机制干扰同源蛋白编码基因的表达调控网络发挥了重要作用。(Genome Biology, 2021)
