摘要:

CRISPR/Cas(Clustered regularly interspaced short palindromic repeats(CRISPR)/CRISPR-associated (Cas)系统是由一种短小RNA调控的对DNA修饰的基因编辑工具,是一种较锌指核酸酶(Zinc-fingers nuclease,ZFN)和转录激活因子样效应物核酸酶(Transcription activator-like (TAL) effector nucleases,TALEN)打靶更加快速、高效、精准的新型基因组编辑工具,它易于设计,且具有特异性。本文回顾了CRISPR/Cas系统的结构与功能,概述了Cas9的设计策略、影响Cas9基因编辑效率的因素、脱靶检测分析方法及其在动物基因编辑研究中的应用。基于CRISPR/Cas9已经在多种动物上成功实现了基因编辑,它有望成为建立动物模型和研究疾病防治的一种新型可行性途径。

Abstract:

CRISPR/Cas (Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated(Cas)) system is a DNA modified gene editing tools regulated by a kind of short RNA.This technology is a novel tool,which is more rapid,efficient and accurate than ZFN (zinc-fingers nuclease) and TALEN (transcription activator-like (TAL) effector nucleases) in genetic engineering.It is easy to be designed and has specificity.This paper reviews the structure and function of CRISPR/Cas9 system and the design strategy of Cas9 and its application in animal genetic engineering.CRISPR/Cas9 is successfully used in a variety of animal genetic editing,it is likely to become a new way to establish animal models and to develop a new feasible approach to prevent disease.
