摘要
CRISPR/Cas9系统已不仅仅是一种革命性的基因编辑工具,还能在各种原核和真核生物中调控基因转录。近年来,由CRISPR/Cas9衍生而来的CRISPR-dCas9系统已被用于基因成像、高通量筛选、基因调控、必需基因功能研究及表观遗传调控等多个方向。总结了近年来CRISPRdCas9系统在激活或抑制基因转录、降低脱靶效率、sgRNA与转录强度及特异性之间的联系等方面的研究进展,以期对CRISPR-dCas9系统定向调控基因转录的研究提供参考和帮助,并就其未来可能的改进进行了展望。
The CRISPR/Cas9 system is not only a revolutionary tool for gene editing but also regulates gene transcription in various prokaryotic and eukaryotic organisms. In recent years,the system of CRISPR-dCas9 derived from CRISPR/Cas9 has been used in many fields such as gene imaging,high-throughput screening,gene regulation,investigating essential gene function and epigenetic regulation. The recent advances of CRISPR-dCas9 for activating or inhibiting gene transcription, reducing off-targeting efficiency and combing the intrinsic relationship between sgRNA and transcriptional regulation,application in the life science and further upgrading were described.
