摘要: N7甲基鸟嘌呤核苷酸(N7-methylguanosine, m7G)是一种常见的RNA转录后修饰,在RNA加工、代谢和功能中起着重要作用。其主要由甲基转移酶1(methyltransferase 1, METTL1)和WD重复结构域4(WD repeat domain 4, WDR4)复合物调控。多项研究表明,METTL1/WDR4复合物促进或抑制许多肿瘤的进程,包括头颈部肿瘤、肺癌、肝癌、结肠癌、膀胱癌和食管鳞癌等,这依赖于tRNA或miRNA的m7G甲基化修饰。因此,METTL1和m7G修饰可以用作生物标志物或潜在的干预靶点,为肿瘤的早期诊断和治疗提供新的方向。本文将主要讨论METTL1通过m7G在肿瘤发生中的作用机制和相关的研究进展。

Abstract:

N7-methylguanosine (m7G) is a common post-transcriptional modification of RNA that plays an important role in RNA processing, metabolism and function and is mainly regulated by the methyltransferase 1 (METTL1) and WD repeat domain 4 (WDR4) complexes. Several studies have shown that the METTL1/WDR4 complex promotes or inhibits the progression of many tumours, including head and neck tumours, lung, liver, colon, bladder and esophageal squamous cancers, which are dependent on m7G methylation modification of tRNA or miRNA. Therefore, METTL1 and m7G modification can be used as biomarkers or potential intervention targets, providing a new direction for early diagnosis and treatment of tumors. This article will mainly discuss the mechanism and corresponding research progress of METTL1 in tumorigenesis through m7G.
