最近生物医学研究中最重要的进展是发现了长度约为22-nt的一类非编码RNA,称为microRNA(miRNAs)。这些调控RNA提供了一种独特的转录后基因调控水平,调节一系列基本的细胞过程。几种病毒,特别是疱疹病毒,也编码miRNA,现在已经鉴定出超过200种病毒miRNA。目前的证据表明,病毒使用这些miRNA来操纵细胞和病毒基因表达。此外,病毒感染可以对细胞miRNA表达谱产生深远影响,并且已经报道了几种RNA病毒与细胞miRNA直接相互作用和/或使用这些miRNA来增强其复制潜力。在这里,我们讨论我们目前的知识病毒的miRNA和病毒影响的细胞的miRNA,以及它们与病毒感染的关系。
The most significant recent advance in biomedical research has been the discovery of the~22-nt long class of non-coding RNAs designated as microRNAs (miRNAs). These regulatory RNAs provide a unique level of post-transcriptional gene regulation that modulates a range of fundamental cellular processes. Several viruses, including especially herpesviruses, also encode miRNAs and over 200 viral miRNAs have now been identified. Current evidence indicates that viruses use these miRNAs to manipulate both cellular and viral gene expression. Furthermore, viral infection can exert a profound impact on the cellular miRNA expression profile, and several RNA viruses have been reported to interact directly with cellular miRNAs and/or to use these miRNAs to augment their replication potential. Here we discuss our current knowledge of viral miRNAs and virally-influenced cellular miRNAs, and their relationship to viral infection.
