不同的细胞类型是在大脑发育的特定时间产生的,并受到表观遗传、转录和新出现的表观转录组学机制的调节。已知RNA修饰影响RNA代谢的许多方面,并且已经涉及各种生物过程的调节和疾病。最近的研究表明,epitranscriptome的失调可能与神经精神,神经发育和神经退行性疾病显着相关。在这里,我们回顾了目前的知识,围绕RNA修饰N6-甲基腺苷,5-甲基胞苷,假尿苷,A-to-I RNA编辑,2 'O-甲基化及其相关机制,在大脑发育和人类疾病中的作用。我们还强调需要开发新技术,以追求在基因组和单分子水平上直接绘制RNA修饰。
Distinct cell types are generated at specific times during brain development and are regulated by epigenetic, transcriptional and newly emerging epitranscriptomic mechanisms. RNA modifications are known to affect many aspects of RNA metabolism and have been implicated in the regulation of various biological processes and in disease. Recent studies imply that dysregulation of the epitranscriptome may be significantly associated with neuropsychiatric, neurodevelopmental, and neurodegenerative disorders. Here we review the current knowledge surrounding the role of the RNA modifications N6-methyladenosine, 5-methylcytidine, pseudouridine, A-to-I RNA editing, 2’O-methylation, and their associated machinery, in brain development and human diseases. We also highlight the need for the development of new technologies in the pursuit of directly mapping RNA modifications in both genome- and single-molecule-level approach.
