CRISPR RNA引导的核酸内切酶(RGen)已迅速成为一种简便有效的基因组编辑平台。在这里,我们使用基于人类细胞的报告实验来表征基于Cas9的抗原的非靶标切割。我们发现,根据引导RNA(GRNA)-DNA界面上的位置不同,单错配和双错配可以被不同程度的容忍。我们通过检查部分不匹配的位点,很容易检测到6个抗原中有4个靶向于人类细胞内源性基因的非靶点改变。我们发现的靶外位点存在多达五个错配,许多突变的频率与预期的靶点上观察到的频率相当(或更高)。我们的工作表明,即使在人类细胞中存在不完全匹配的RNA-DNA接口,抗原也是高度活跃的,这一发现可能会混淆它们在研究和治疗应用中的用途。
CRISPR RNA-guided endonucleases (RGENs) have rapidly emerged as a facile and efficient platform for genome editing. Here, we use a human cell-based reporter assay to characterize off-target cleavage of Cas9-based RGENs. We find that single and double mismatches are tolerated to varying degrees depending on their position along the guide RNA (gRNA)-DNA interface. We readily detected off-target alterations induced by four out of six RGENs targeted to endogenous loci in human cells by examination of partially mismatched sites. The off-target sites we identified harbor up to five mismatches and many are mutagenized with frequencies comparable to (or higher than) those observed at the intended on-target site. Our work demonstrates that RGENs are highly active even with imperfectly matched RNA-DNA interfaces in human cells, a finding that might confound their use in research and therapeutic applications.
