摘  要:
通过CRISPR/Cas系统来构建miR-17-92基因簇的双切载体,研究结果表明:在miR-17-92基因簇的序列上找到了2个PAM(TGG和GGG)位点,从而得到了2个原间隔序列,设计合成基因簇双链crRNA;合成该片段并将其插入到p X260载体,使得在同一个载体上虽然只有一个g-RNA,但能够同时切割两个不同的靶位点;将该载体转染NIH3T3细胞验证切割效率,PCR结果和测序结果显示,所构建的CRISPR系统可以对基因片段进行有效切割。

摘  要:
We constructed double-cut carrier of miR-17-92 gene cluster using CRISPR / Cas9 system. We identified two PAM and two protospacesare,and designed pre-crRNAs. The synthesized pre-crRNAs( that was the designed annealing oligonucleotides based on the sequence specific) were inserted between the pX 260 carrier. Therefore,there is only one g-RNA in the same carrier,cutting two different target sites at the same time. NIH3T3 cells were transfected by plasmid of pX 260 carrier including pre-crRNAs for the cutting effect. The miR-17-92 gene was cut by CRISPR / Cas system.
