In the past few years, technological advances in nucleotide sequencing have culminated in a greater understanding of the complexity of the human transcriptome. Notably, the discovery that distal regulatory elements known as enhancers are transcribed and such enhancer-derived transcripts (eRNAs) serve a critical function in transcriptional activation has added a new dimension to transcriptional regulation. Here we review recent insights into the tissue-specific and temporal-specific gene regulation brought about by the discovery of eRNAs.
在过去的几年中,核苷酸测序技术的进步使得人们对人类转录组的复杂性有了更深入的了解。值得注意的是,人们发现了一种被称为增强子的远端调控元件可以被转录,而这些增强子衍生的转录本(eRNAs)在转录激活中起着关键作用,这为转录调控增添了一个新的维度。在这里,我们回顾了最近关于发现 eRNAs 带来的组织特异性和时间特异性基因调控的新见解。
