Long non-coding RNAs (lncRNAs) are diverse transcription products emanating from thousands of loci in mammalian genomes. Cis-acting lncRNAs, which constitute a substantial fraction of lncRNAs with an attributed function, regulate gene expression in a manner dependent on the location of their own sites of transcription, at varying distances from their targets in the linear genome. Through various mechanisms, cis-acting lncRNAs have been demonstrated to activate, repress or otherwise modulate the expression of target genes. We discuss the activities that have been ascribed to cis-acting lncRNAs, the evidence and hypotheses regarding their modes of action, and the methodological advances that enable their identification and characterization. The emerging principles highlight lncRNAs as transcriptional units highly adept at contributing to gene regulatory networks and to the generation of fine-tuned spatial and temporal gene expression programmes.

通过顺式作用的长非编码RNA调控基因表达。

长非编码RNA(lncRNA)是来自哺乳动物基因组中数千个基因座的多种转录产物。顺式作用的lncRNA构成了具有一定功能的lncRNA的主要部分,它以依赖于其自身转录位点的位置的方式调节基因表达,且距离其在线性基因组中的靶点的距离不同。通过多种机制,已证明顺式作用的lncRNA可激活,抑制或调节靶基因的表达。我们讨论了归因于顺式作用lncRNA的活动,有关其作用方式的证据和假设,以及能够对其进行鉴定和表征的方法学进展。
