A significant portion of the mammalian genome encodes numerous transcripts that are not translated into proteins, termed long non-coding RNAs. Initial studies identifying long non-coding RNAs inferred these RNA sequences were a consequence of transcriptional noise or promiscuous RNA polymerase II activity. However, the last decade has seen a revolution in the understanding of regulation and function of long non-coding RNAs. Now it has become apparent that long non-coding RNAs play critical roles in a wide variety of biological processes. In this review, we describe the current understanding of long non-coding RNA-mediated regulation of cellular processes: differentiation, development, and disease.
哺乳动物基因组的很大一部分编码了许多未翻译成蛋白质的转录本,这些转录本被称为长链非编码RNA。最初鉴定长链非编码RNA的研究推断,这些RNA序列是转录噪声或RNA聚合酶II随机活性的结果。然而,在过去十年中,人们对长链非编码RNA的调控和功能的理解发生了革命性的变化。现在已经很明显,长链非编码RNA在多种生物学过程中发挥着关键作用。在这篇综述中,我们描述了目前对长链非编码RNA介导的细胞过程调控的理解:分化、发育和疾病。
