摘要

CRISPR/Cas 系统已成为基因组工程的强大工具。最近的研究强调了转座元件(TEs)的关键作用,激发了人们对操纵这些元件以了解其功能的研究兴趣。然而,考虑到转座元件的序列重复性和高拷贝数,设计特异且高效的单导RNA(sgRNA)来操纵转座元件是一项重大挑战。虽然已经开发出多种用于基因编辑的 sgRNA 设计工具,但用于 TE 操作的优化 sgRNA 设计器仍有待建立。我们介绍的 CRISPR-TE 是一种基于网络的应用程序,具有易于访问的图形用户界面,可通过 https://www.crisprte.cn/ 获取,目前专为人类和小鼠基因组定制。CRISPR-TE 可识别 TE 的所有潜在 sgRNA,并为单拷贝和亚家族水平的高效 TE 靶向提供全面的解决方案。我们的分析表明,靶向 TE 的 sgRNA 在亚家族水平上可以更有效地靶向具有保守序列的进化年轻 TE。CRISPR-TE 为设计用于 TE 靶向的 sgRNA 提供了一个多功能框架。CRISPR-TE 可在 https://www.crisprte.cn/ 上以在线网络服务的形式公开访问,CRISPR-TE 的源代码可在 https://github.com/WanluLiuLab/CRISPRTE/ 上获取。

CRISPR-TE: a web-based tool to generate single guide RNAs targeting transposable elements
The CRISPR/Cas systems have emerged as powerful tools in genome engineering. Recent studies highlighting the crucial role of transposable elements (TEs) have stimulated research interest in manipulating these elements to understand their functions. However, designing single guide RNAs (sgRNAs) that are specific and efficient for TE manipulation is a significant challenge, given their sequence repetitiveness and high copy numbers. While various sgRNA design tools have been developed for gene editing, an optimized sgRNA designer for TE manipulation has yet to be established. We present CRISPR-TE, a web-based application featuring an accessible graphical user interface, available at https://www.crisprte.cn/ , and currently tailored to the human and mouse genomes. CRISPR-TE identifies all potential sgRNAs for TEs and provides a comprehensive solution for efficient TE targeting at both the single copy and subfamily levels. Our analysis shows that sgRNAs targeting TEs can more effectively target evolutionarily young TEs with conserved sequences at the subfamily level. CRISPR-TE offers a versatile framework for designing sgRNAs for TE targeting. CRISPR-TE is publicly accessible at https://www.crisprte.cn/ as an online web service and the source code of CRISPR-TE is available at https://github.com/WanluLiuLab/CRISPRTE/ .
