摘要
背景:尽管可以转录多达90%的真核基因组,但只有1-2%的所得转录本编码蛋白质,而其余的可以分类为非编码RNA(ncRNA),其主要由长ncRNA(lncRNAs)组成)和小ncRNAs。总体来说,他们被建议针对基因组中的特定区域,并在许多重要的生物过程中发挥多方面的作用。 总结:最近的证据表明,ncRNAs在脑中大量表达,其中许多在神经障碍中被异常调节。然而,它们在相关生理和病理过程中的功能相关性尚未得到充分的了解。因此,阐明ncRNA在脑中的作用将大大增强目前对神经发育的认识,最终导致治疗神经疾病的新策略。在本报告中,我们回顾了lncRNAs和各种类型的小ncRNAs在脑发育和神经障碍中的结构和机制。 观点:我们希望对这些ncRNA的广泛研究将揭示和表征脑中的新型分子电路,并促进为患有神经障碍的人开发基于RNA的治疗剂。

Title:Non-Coding RNA in Brain Development and Disorder
Volume: 24 Issue: 18

摘要: Background: Although up to 90% of the eukaryotic genome can be transcribed, only 1-2% of the resultant transcripts encode for proteins, while the remaining can be classified as non-coding RNAs (ncRNAs) which mostly consist of long ncRNAs (lncRNAs) and small ncRNAs. In overall, they have been suggested to target specific regions in the genome and play multi-faceted roles in many important biological processes.
Summary: Recent evidence has shown that ncRNAs are abundantly expressed in the brain and many of them are aberrantly regulated in neural disorders. Yet their functional relevance in related physiological and pathological processes has not been adequately understood. Thus, the elucidation of the role of ncRNAs in the brain would greatly enhance the current understanding of neural development and ultimately lead to novel strategies to treat neural diseases. In this report, we reviewed the structure and mechanism of lncRNAs and various classes of small ncRNAs in brain development and neural disorders. Perspective: We hope that extensive studies of these ncRNAs would unravel and characterize novel molecular circuits in the brain, and facilitate the development of RNA-based therapeutics for people suffering from neural disorders.Export Options
