We employ the CRISPR-Cas system of Streptococcus pyogenes as programmable RNA-guided endonucleases (RGENs) to cleave DNA in a targeted manner for genome editing in human cells. We show that complexes of the Cas9 protein and artificial chimeric RNAs efficiently cleave two genomic sites and induce indels with frequencies of up to 33%.
我们利用酿脓链球菌的 CRISPR-Cas 系统作为可编程的 RNA 指导内切核酸酶(RGENs),以靶向方式切割 DNA,从而对人类细胞进行基因组编辑。我们表明,Cas9 蛋白和人工嵌合 RNA 的复合物能够有效地切割两个基因组位点,并以高达 33%的频率诱导插入缺失。
