摘要: microRNAs (miRNAs)是一类通常存在于细胞质中的短链非编码RNAs，通过与信使RNA (mRNA)的3'非翻译区(3'untranslated region, 3'UTR)结合，发挥调节转录后基因表达的功能。miRNAs在调控多种代谢过程和信号转导途径方面起着重要作用。线粒体是真核细胞中进行氧化代谢和ATP合成的关键场所，负责糖类、脂质和氨基酸等大分子的代谢。那些特异性定位于线粒体的miRNAs，以及在细胞质中直接或间接调节线粒体特定功能的miRNAs，被称为线粒体miRNAs (mitochondrial miRNAs, mitomiRs)。这些miRNAs能调控相关基因表达，并在关键线粒体代谢途径中发挥独特作用，从而促进肿瘤的发生与发展。本文重点探讨mitomiR在线粒体中的作用以及在肿瘤中的调控机制，旨在进一步阐明肿瘤发生发展的分子机制，开发潜在的癌症新疗法。
Abstract: microRNAs (miRNAs) are a class of short non-coding RNAs typically found in the cytoplasm. They function to regulate post-transcriptional gene expression by binding to the 3' untranslated region (3'UTR) of messenger RNA (mRNA). miRNAs play a crucial role in modulating various metabolic processes and signal transduction pathways. Mitochondria serve as the primary sites for oxidative metabolism and ATP synthesis in eukaryotic cells, and they are responsible for the metabolism of macromolecules, including sugars, lipids, and amino acids. Mitochondrial miRNAs (mitomiRs) are a subset of miRNAs localized specifically within mitochondria and modulate mitochondrial-specific functions, either directly or indirectly, within the cytoplasm. These mitomiRs can modulate gene expression and have a distinct role in pivotal mitochondrial metabolic pathways, thereby influencing the initiation and progression of tumors. This article concentrates on the role of mitomiRs in mitochondria and their regulatory mechanisms in tumorigenesis, with the goal of further elucidating the molecular underpinnings of tumorigenesis and development, and of identifying potential novel therapeutic targets for cancer.
