人类LncRNA的数量现已超过所有已知的蛋白质编码基因。人类LncRNA的大多数研究都是在细胞培养系统中进行的,其中已经确定了各种作用机制。另一方面,阐明人LncRNA在体内环境中的功能的努力受到限制。在这篇简短的综述中,我们强调了在小鼠中研究人类LncRNA的一些优点和缺点。特别考虑细菌人工染色体转基因和基因组编辑。这些技术创新的整合为补充和扩展用于人类LncRNA研究的细胞培养模型的广泛文献提供了前所未有的机会。介绍了两个不同的例子,说明如何利用BAC转基因和基因组编辑来深入了解小鼠中的人类LncRNA调控和功能:血管细胞富集LncRNA的随机整合和ACE 2基因上游新LncRNA的靶向方法,ACE 2基因编码严重急性呼吸综合征冠状病毒2型受体(SARS-CoV-2),是导致冠状病毒病-19(COVID-19)大流行的病原体。
The number of human LncRNAs has now exceeded all known protein-coding genes. Most studies of human LncRNAs have been conducted in cell culture systems where various mechanisms of action have been worked out. On the other hand, efforts to elucidate the function of human LncRNAs in an in vivo setting have been limited. In this brief review, we highlight some strengths and weaknesses of studying human LncRNAs in the mouse. Special consideration is given to bacterial artificial chromosome transgenesis and genome editing. The integration of these technical innovations offers an unprecedented opportunity to complement and extend the expansive literature of cell culture models for the study of human LncRNAs. Two different examples of how BAC transgenesis and genome editing can be leveraged to gain insight into human LncRNA regulation and function in mice are presented: the random integration of a vascular cell-enriched LncRNA and a targeted approach for a new LncRNA immediately upstream of the ACE2 gene, which encodes the receptor for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiologic agent underlying the coronavirus disease-19 (COVID-19) pandemic.
