摘要:

CRISPR/Cas9系统是一种近年来被广泛应用于基因组编辑的强大工具。通过将CRISPR/Cas9系统中的Cas9蛋白突变后,使其失去剪切活性而成为dCas9 (nuclease-dead Cas9),再结合基因功能丧失(loss-of-function, LOF)、基因功能激活(gain-of-function, GOF)以及非编码功能基因鉴定技术即可实现全基因组高通量的功能基因及调控元件靶向鉴定和筛选。目前,该技术已被广泛应用于疾病免疫机理、药物靶点筛选和动物遗传育种等研究,为生命医学和基础科学带来了全新高效的技术方法和研究思路。本文综述了基于CRISPR/Cas9技术在全基因组中高通量筛选功能基因及调控元件的方法及研究进展,重点阐述了CRISPR/Cas9系统在动物细胞中筛选功能性基因的方法,以期为基因编辑及相关研究领域提供参考。

Abstract:

The CRISPR/Cas9 system is a powerful tool which has been extensively used for genome editing in the past few years. Nuclease-dead Cas9 (CRISPR/dCas9), a Cas9 protein mutant without splicing ability, along with loss-of- function (LOF), gain-of-function (GOF), or non-coding genes scanning approaches can reveal genome-scale functional determinants. CRISPR/Cas9 has been widely adopted to decipher disease mechanisms and pinpoint drug targets in the life science field, and also provide novel insights into animal genetics and breeding. In this review, we summarize the research progress in high-throughput CRISPR/Cas9 screening for revealing the functional genes and regulatory elements in the whole genome. We also highlight the applications of CRISPR/Cas9 system in the animal cells, providing a reference for gene editing and other related research in related fields.

Key words: CRISPR/Cas9, genome-wide screening, functional gene, regulatory elements
