It has long been assumed that miRNAs can only target protein-coding mRNAs in the cytoplasm. Recent studies, however, reveal miRNAs are also transported from the cytoplasm to the nucleus, where they function in a noncanonical manner to regulate noncoding RNAs. Here, we highlight the working model of these noncanonical miRNAs.
长期以来,人们一直认为 miRNA 只能靶向细胞质中的蛋白质编码 mRNA。然而,最近的研究表明,miRNA 也可以从细胞质运输到细胞核,在细胞核中以非典型方式发挥作用,调节非编码 RNA。在这里,我们重点介绍这些非典型 miRNA 的工作模式。
