摘要: 近年来, 随着人们对CRISPR-Cas系统研究的不断深入和改造, CRISPR-Cas系统已成为一项新的基因靶向修饰技术, 能够定向对靶基因进行定向沉默, 目前该项技术已经成功地用于HEK293、小鼠及斑马鱼的细胞并产生了稳定的基因敲除细胞株, 在小鼠、果蝇等模式动物上成功构建了基因敲除模型。CRISPR-Cas以其设计简单, 耗时短、效率高等优点使其成为一项具有广阔应用前景的基因靶向敲除技术。就CRISPR-Cas的发现、结构、作用机理以及Cas9/gRNA目前的一些应用进行综述。

关键词: CRISPR-Cas, 基因修饰, 基因敲除

Abstract: Recently, with the deepening of the research and transformation of CRISPR-Cas system, it has been applied as a new gene targeting modification technology, which can be directed to silence target genes. At present, this technology has been successfully used in HEK293, mouse and zebrafish cells and generated stable gene knockout cell lines, meanwhile gene knockout models has been constructed on the models animals such as mice and fruit flies. With the advantages of simple design, short time-consuming and higher efficiency, CRISPR-Cas has become a gene targeting knockout technology with broad application prospect. In this paper, structure and function mechanism of the CRISPR-Cas, also the current applications of Cas9/gRNA were reviewed.

Key words: CRISPR-Cas, Genetic modification, Gene knockout
