Strategies for Optimization of the Clustered Regularly Interspaced Short Palindromic Repeat-Based Genome Editing System for Enhanced Editing Specificity
HUMAN GENE THERAPY(2022)
摘要
The clustered regularly interspaced short palindromic repeats (CRISPR) system is inarguably the most valuable gene editing tool ever discovered. Currently, three classes of CRISPR-based genome editing systems have been developed for gene editing, including CRISPR/CRISPR associate system (Cas) nucleases, base editors, and prime editors. Ever-evolving CRISPR technology plays an important role in medicine; however, the biggest obstacle to its use in clinical practice is the induction of off-target effects (OTEs) during targeted editing. Therefore, continuous improvement and optimization of the CRISPR system for reduction of OTEs is a major focus in the field of CRISPR research. This review aims to provide a comprehensive guide for optimization of the CRISPR-based genome editing system.
