摘要: 利用功能缺失型(Loss-of-function)或者功能获得型(Gain-of-function) 策略高通量筛选功能基因,是研究人员快速寻找调控特定表型的重要或关键基因的主要方法。RNA干扰(RNA interference,RNAi)的遗传筛选方法因操作简单、成本相对较低等优势,尽管已经得到了广泛的应用,然而其抑制效果不完全、脱靶效应明显等劣势依然存在。近年来兴起的CRISPR/Cas9 (Clustered regularly interspaced short palindromic repeat sequences/ CRISPR-associated protein 9)技术能快速、简便、准确地实现基因组敲除等编辑功能,因而成为一种强大的遗传筛选工具;在各种细胞系、人和小鼠及斑马鱼等多种模式动物中,大规模运用该方法筛选功能基因已经取得了巨大成功。本文总结了CRISPR/Cas9技术的特点,将其与传统基因工程方法进行了分析比较,回顾了近期相关的高通量功能基因筛选工作,最后探讨了该技术未来的发展趋势。

Abstract: High-throughput screening, a powerful tool for the discovery of functionally important genes responsible for certain phenotypes, is performed according to loss-of-function or gain-of-function strategies. RNAi technology or knockout approaches have been widely used in high throughput screening due to their advantages of ease use, low cost and so on. However, imcomplete knockdown activity and off-target effect hindered their utility. More recently, CRISPR/Cas9 technology is becoming a robust tool for genome editing in diverse cells or animals, since it could generate a gene mutation in a target-specific manner. In this review, we first summarize the characterization of CRISPR/Cas9 and make comparison with traditional genetic tools, then describe recent achievements of genetic screen in several model organisms using CRISPR/Cas9, finally discuss on its future challenges and opportunities.
