CRISPR-Cas9 系统是精确修改模型生物体基因组的有力而有效的工具。在这里, 我们演示了嵌合体 sgRNAs20与 ssODN HDR 模板结合在一起, 使得在C. 线虫中高效地生成基因组点突变。重要的是, 我们表明, RNP 交付产生高编辑效率时, 荧光作为一个联合选择标记, 突出的易用性和可靠性的技术。
C. 线虫基因组工程的大多数 CRISPR-Cas9 方法都依赖于特定的遗传背?...

最近的技术进步已经从根本上改变并加速了精确地设计基因组的能力。特别是, 依靠 RNA 引导的限制性 Cas9 在目标序列附近诱导双链断裂 (CRISPR-Cas9) 的系统, 已被广泛地用于精确地设计大多数模型生物体的基因组, 用于生物医学研究1,2,3,4。重要的是, 即使在诸如线虫5这样的困难物种中, CRISPR-Cas9 的使用也没有锁定基因组编辑。无论物种, 产生点突变与基于 CRISPR-Cas9 的基因组编辑系统依赖于三核心组件: 1) Cas9 限制性, 2) 一个单一的指南 RNA (sgRNA), 指示 Cas9 限制性到目标序列, 3) 用户设计同源定向修复 (HDR) 模板, 其中包含所需的感兴趣的编辑2。
有几种方法可用于将靶向 sgRNA 和 Cas9 核酸酶引入细胞, 包括质粒、RNA 和基于病毒的传递方法 6.最近, 在 CRISPR-Cas9-based 基因组编辑7中, 直接交付预复合 sgRNA-Cas9 Ribonucleoproteins (RNPs) 已成为一个强大而有效的工具。预复杂 CRISPR-Cas9 RNPs 的直接传递有几个明显的优点, 即: 1) RNPs 绕过细胞转录和翻译的需要, 2) RNPs 迅速清除, 这可能会增加特异性通过减少可用时间离靶解理和 3) RNPs 不包含外来的 DNA/RNA 元素, 通过随机积分绕过非本机序列引入宿主基因组。在一起, 这些属性可能会提供一个短暂的 CRISPR 的目标编辑, 同时尽量减少目标效果。
我们描述了一种简单有效的协议, 用于在C. 线虫中引入特定于站点的基因组变化。该协议包括目标 sgRNA 和单链寡核苷酸 (ssODN) HDR 模板设计, sgRNA-Cas9 RNP 络合和交付, 以及一个基因分型策略, 以明确识别正确编辑的动物。使用此策略, 不仅可以恢复所需的站点特定更改, 而且还可以恢复其他非特定的 indel 突变。因此, 我们的策略允许使用单一的策略生成一个二等位序列, 在这个方法中, 可以在 F1生成中生成单位、双位和 indel 突变体。
