一旦一个基因被关闭,在细胞以后的数百代中,该基因仍然是惰性的,除非它被称为CRISPRon的互补工具重新打开。 这项技术以 CRISPR 系统为基础,开发出了一套全新的表观遗传编辑器 CRISPRoff,其瞬时表达便可实现持久可遗传、而且可逆转的 DNA 甲基化修饰和基因转录调控,有效地弥补了现有的转录调控/表观遗传编辑工具,例如...
据中科博生了解,研究人员构建出了一种称为CRISPR-on的强大新基因调控系统,这种系统的作用与RNAi的作用相反——RNAi通常用于失活基因活性,CRISPR-on则可以激活一些细胞基因,由此能增强研究过程中改变基因表达的能力。中科博生。在之前的研究中,Jaenisch教授曾利用CRISPR/ Cas的系统绕过ES细胞,快速有效地生成多个基因双拷贝...

With the first UK and US human trials using the potentially revolutionary CRISPR gene editing technique about to commence, several questions still hover over the ultimate safety of this system. A
The researchers used their system, dubbed CRISPRoff and CRISPRon, to induce pluripotent stem cells to transform into neurons. They also used it to silence the gene that makes the protein Tau, which has been implicated in Alzheimer’s disease. They descri...
Since the advent of CRISPR-Cas9, a groundbreaking gene-editing technology that enables precise genomic modifications via a short RNA guide sequence, there has been a marked increase in the accessibility and application of this technology across various fields. The success of CRISPR-Cas9 has spurred ...
CRISPR is widely used to silence genes by inducing mutations expected to nullify their expression. While numerous computational tools have been developed to design single-guide RNAs (sgRNAs) with high cutting efficiency and minimal off-target effects, on
The 2023 International Conference on CRISPR Technologies will focus on the latest advances in the genome editing field, bringing together key stakeholders with aligned interests across the spheres of academia and industry. The program will feature talks across many facets of this field, including the ...
ProCas9可以检测到一种叫做蛋白酶的酶的存在。ProCas9(左,灰色)无效,直到蛋白酶剪断一小段蛋白质(红色环),此时它变得活跃(正确,红色)并结合DNA。通过使Cas9在结合DNA时发出荧光,研究人员得到了蛋白酶存在的信号。 CRISPR-Cas9是一种革命性的工具,部分原因在于其多功能性:由细菌产生的咀嚼病毒,它在人体细胞中同样...
