最近的发现,人类和其他哺乳动物基因组产生了数千个长期的非编码RNA(LNCRNA)提出了许多有趣的问题。这些缺乏明显蛋白质编码能力的mRNA样分子通过多种多样的分子机制涉及广泛的生物学功能。尽管最近对LNCRNA在各种细胞过程中的作用,例如调节基因表达和细胞结构的组装,总的来说,有关LNCRNA机制的关键问题仍然有待回答。在这篇综述中,我们讨论了了解LNCRNA的生物学的最新进展,并提出了调查途径,这可能会导致对其功能和作用机制的基本新见解。最后,由于许多LNCRNA在人类疾病和疾病中失调,我们还讨论了这些分子在人类健康中的潜在作用。
The recent discovery that the human and other mammalian genomes produce thousands of long non-coding RNAs (lncRNAs) raises many fascinating questions. These mRNA-like molecules, which lack significant protein-coding capacity, have been implicated in a wide range of biological functions through diverse and as yet poorly understood molecular mechanisms. Despite some recent insights into how lncRNAs function in such diverse cellular processes as regulation of gene expression and assembly of cellular structures, by and large, the key questions regarding lncRNA mechanisms remain to be answered. In this review, we discuss recent advances in understanding the biology of lncRNAs and propose avenues of investigation that may lead to fundamental new insights into their functions and mechanisms of action. Finally, as numerous lncRNAs are dysregulated in human diseases and disorders, we also discuss potential roles for these molecules in human health.
