CRISPR-Cas9 genome editing exploits the CRISPR-Cas system to modify a genome in a targeted manner. Guided by RNA, the Cas9 endonuclease breaks DNA at a target sequence. Imprecise repair of the double strand break can result in insertion or deletion mutations, while repair pathways can be engine...
5. Construction of pCas9-T1-target as the following protocol. ① Digestion of pCas9-T1: SmaI ② PCR: Target ü Template: plasmid pCas9-T1 (100x dilution) ü Primers: l Target-UP: U6-26P-common-F, Target-Cas9-R→~170 bp l Target-DN: Target-Cas9-F, U6-26T-common-R→~160 b...
A CRISPR/Cas9 nuclease system requires two components: a Cas enzyme for cutting the target sequence and a single guide RNA (sgRNA), which binds to the target sequence of 20-base pair (bp). The target sequence (complementary to the sgRNA sequence) is followed by two cytosine nucleotides becau...
未来的探索方向包括:拓展Cas9的应用范围,将其应用在经济作物品质改良中:在Cas9和sRNA加上核定位信号促,使它们在细胞核内特异表达:对比不同来源的各种启动子(比如H1启动子、拟南芥U6启动子、烟草U6启动子、UBI启动子、35S启动子等)的靶标范围、精准度和表达效率,选择适用于目标植物的启动子:寻找改造甚至突破 PAM序列...

2021年6月26日,NEJM杂志发表了一篇题为:CRISPR-Cas9 In Vivo Gene Editing for Transthyretin Amyloidosis 的论文,公布了诺奖得主Jennifer Doudna创立的IntelliaTherapeutics和再生元合作开发治疗转甲状腺素蛋白淀粉样变性(ATTR)的CRISPR基因编辑疗法NTLA-2001I期临床结果(NCT04601051)。据悉,这也是首个公布的体内CRISPR基因编...
At the mRNA level, CRISPR-Cas9 editing causes deletion of 9–24 nucleotides at the DSB sites. These deletions resulted in a complete loss of mdig protein expression. Unexpectedly, this CRISPR-Cas9-based gene editing also induced alternative splicing of the mdig mRNAs due to exon skipping and ...
