典型地,microRNAs(miRNAs)控制mRNA表达。然而,研究表明,miRNA也能够靶向非编码RNA,包括长非编码RNA和miRNA。后者称为miRNA:miRNA相互作用,是一种自我调节形式。本文就miRNA的三种主要调控方式:直接、间接和全局相互作用及其在肿瘤生物学中的意义进行综述。我们还讨论了细胞类型特异性的miRNA:miRNA相互作用,目前的实验方法和生物信息学技术,以及这些策略是如何不足以识别新的miRNA:miRNA相互作用。miRNAs的自我调节及其对基因调控的影响尚未完全了解。研究这个隐藏的miRNA自我调节世界将有助于发现与疾病途径相关的新的调节机制。总结:microRNA能够自我靶向,这对它们的生物发生、它们在基因调控中的典型作用和癌症发展具有影响。
Canonically, microRNAs (miRNAs) control mRNA expression. However, studies have shown that miRNAs are also capable of targeting non-coding RNAs, including long non-coding RNAs and miRNAs. The latter, termed a miRNA:miRNA interaction, is a form of self-regulation. In this Review, we discuss the three main modes of miRNA:miRNA regulation: direct, indirect and global interactions, and their implications in cancer biology. We also discuss the cell-type-specific nature of miRNA:miRNA interactions, current experimental approaches and bioinformatic techniques, and how these strategies are not sufficient for the identification of novel miRNA:miRNA interactions. The self-regulation of miRNAs and their impact on gene regulation has yet to be fully understood. Investigating this hidden world of miRNA self-regulation will assist in discovering novel regulatory mechanisms associated with disease pathways. Summary: MicroRNAs are capable of self-targeting, which has implications on their biogenesis, their canonical role in gene regulation and on cancer development.
