CRISPR/Cas系统是一种有效的基因组编辑工具,可以修改小鼠受精卵中的基因。然而,只有化脓性链球菌Cas9(SpCas 9)已经被系统地测试用于产生基因修饰的小鼠。SpCas 9识别的原型间隔区邻近基序(PAM,5′-NGG-3′)限制了该系统的潜在靶位点的数量。金黄色葡萄球菌Cas9(SaCas 9)具有较小的尺寸和独特的PAM(5′-NNGRRT-3′)偏好,为合子中的基因组编辑提供了替代方案。在这里,我们表明SaCas 9可以有效和特异性地编辑小鼠合子中的X连锁基因Slx 2和常染色体基因Zp 1。SaCas 9介导的酪氨酸酶(Tyr)基因的破坏导致C57 BL/6 J小鼠具有马赛克毛色。此外,当我们将靶向Slx 2、Zp 1和Tyr的gRNA与SaCas 9 mRNA一起共注射时,多重靶向证明了有效的多基因破坏。当Flag编码单链DNA寡核苷酸与SaCas 9 mRNA和gRNA共引入小鼠受精卵时,我们还能够在组蛋白H1 c的C末端插入Flag标签。这些结果表明,SaCas 9可以特异性切割靶基因位点,导致小鼠受精卵中成功的基因敲除和精确敲入,并突出了使用SaCas 9在植入前胚胎中进行基因组编辑和产生基因修饰动物模型的潜力。
The CRISPR/Cas system is an efficient genome-editing tool to modify genes in mouse zygotes. However, only the Streptococcus pyogenes Cas9 (SpCas9) has been systematically tested for generating gene-modified mice. The protospacer adjacent motif (PAM, 5′-NGG-3′) recognized by SpCas9 limits the number of potential target sites for this system. Staphylococcus aureus Cas9 (SaCas9), with its smaller size and unique PAM (5′-NNGRRT-3′) preferences, presents an alternative for genome editing in zygotes. Here, we showed that SaCas9 could efficiently and specifically edit the X-linked gene Slx2 and the autosomal gene Zp1 in mouse zygotes. SaCas9-mediated disruption of the tyrosinase (Tyr) gene led to C57BL/6J mice with mosaic coat color. Furthermore, multiplex targeting proved efficient multiple genes disruption when we co-injected gRNAs targeting Slx2, Zp1, and Tyr together with SaCas9 mRNA. We were also able to insert a Flag tag at the C-terminus of histone H1c, when a Flag-encoding single-stranded DNA oligo was co-introduced into mouse zygotes with SaCas9 mRNA and the gRNA. These results indicate that SaCas9 can specifically cleave the target gene locus, leading to successful gene knock-out and precise knock-in in mouse zygotes, and highlight the potential of using SaCas9 for genome editing in preimplantation embryos and producing gene-modified animal models.
