microRNAs (miRNAs) are small noncoding RNAs that play important roles in posttranscriptional gene regulation. In animal cells, miRNAs regulate their targets by translational inhibition and mRNA destabilization. Here, we review recent work in animal models that provide insight into the diverse roles of miRNAs in vivo.

microRNA功能。

microRNA（miRNA）是小的非编码RNA，在转录后基因调控中起重要作用。在动物细胞中，miRNA通过翻译抑制和mRNA不稳定来调节其靶标。在这里，我们回顾了动物模型中的最新工作，这些工作为深入了解miRNA在体内的各种作用提供了见识。
