摘要: |
长链非编码RNA(long noncoding RNA,lncRNA)是一类长度超过200个核苷酸的非编码RNA分子,其数量众多,但缺少蛋白质编码功能。研究发现,lncRNA能在表观遗传学、转录及转录后等多种水平调控基因的表达,在各类生物过程中起着重要的调节作用,并与多种疾病相关,已经成为现代遗传学的研究热点。近期研究证据显示,肺癌中有多种lncRNA的表达水平发生了变化,并在肺癌的发生、发展及预后中起着重要的调控作用。本文就lncRNA的定义、功能机制及与肺癌的相关性研究作一综述。 |

Abstract: |
Long noncoding RNAs (lncRNAs),contraining more than 200 nucleotides,are RNA transcripts without protein-coding capacity.It has been reported that lncRNAs regulate gene expression at the epigenetic,transcriptional and post-transcriptional levels,and are deeply involved in various biological processes.Many diseases are found related to lncRNAs and they have become a focus of studies.According to recent evidences,a number of lncRNAs are changed in lung cancer,and they play a significant part in the development,progression and prognosis of lung cancer.This review focuses on the definition and functional mechanism of lncRNAs and their relation with lung cancer. |
