工程内切酶,如锌指核酸酶(ZFNs)、转录激活因子样效应核酸酶(TALENs)和聚集规律间隔短回传重复(CRISPR)/CRISPR相关(Cas)系统,为动物基因组编辑提供了一种强大的方法。然而,将内切酶微量注入胚胎需要较高的技术水平,耗时长,并且可能对胚胎造成损伤。在这里,我们证明将内切酶mrna电穿孔到完整的胚胎中可以诱导靶向位点的编辑,并有效地产生基因敲除大鼠。值得注意的是,ZFNs的电穿孔导致胚胎存活率(91%)和基因组编辑率(73%)比常规显微注射的相应率高出2倍以上。电穿孔技术为基因敲除动物的产生提供了一种简单有效的方法。
Engineered endonucleases, such as zinc-finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and the clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated (Cas) system, provide a powerful approach for genome editing in animals. However, the microinjection of endonucleases into embryos requires a high skill level, is time consuming, and may cause damage to embryos. Here, we demonstrate that the electroporation of endonuclease mRNAs into intact embryos can induce editing at targeted loci and efficiently produce knockout rats. It is noteworthy that the electroporation of ZFNs resulted in an embryonic survival rate (91%) and a genome-editing rate (73%) that were more than 2-fold higher than the corresponding rates from conventional microinjection. Electroporation technology provides a simple and effective method to produce knockout animals.
