RNA甲基化是一种可逆的RNA转录后修饰,对许多生物学过程具有重要影响。N6-甲基腺苷(m6 A)是真核生物中最常见的mRNA甲基化修饰类型之一,广泛存在于病毒、酵母、植物、小鼠和人类等多种生物体中。广泛和动态的m6 A甲基化在脑中的不同发育阶段中被鉴定,并且控制神经干细胞的发育及其分化成神经元、神经胶质细胞如少突胶质细胞和星形胶质细胞。在这里,我们总结了最近的进展,我们的理解RNA甲基化调控在脑发育,神经发生,胶质细胞,及其失调的脑肿瘤。本文将重点介绍RNA甲基化在神经元和神经胶质细胞发育和功能中的生物学作用,并为脑肿瘤的形成以及诊断和治疗策略提供见解。
RNA methylation is a reversible post-transcriptional modification to RNA and has a significant impact on numerous biological processes. N 6-methyladenosine (m6A) is known as one of the most common types of eukaryotic mRNA methylation modifications, and exists in a wide variety of organisms, including viruses, yeast, plants, mice, and humans. Widespread and dynamic m6A methylation is identified in distinct developmental stages in the brain, and controls development of neural stem cells and their differentiation into neurons, glial cells such as oligodendrocytes and astrocytes. Here we summarize recent advances in our understanding of RNA methylation regulation in brain development, neurogenesis, gliogenesis, and its dysregulation in brain tumors. This review will highlight biological roles of RNA methylation in development and function of neurons and glial cells, and provide insights into brain tumor formation, and diagnostic and treatment strategies.
