/A Tool To Validate The Safety Of Gene Editing Systems
AsianScientist (Mar. 12, 2019) – A team of international scientists has developed a technique to evaluate the safety of genome-editing techniques. The research was published in Science. CRISPR-Cas9 is a new generation of gene-editing tool that has been widely used. However, the risk of off-target effects in vivo, which could lead to diseases such as cancer, remains a serious concern. A variety of off-target detection schemes have been developed, with most relying on the prediction of off-target sites based on sequence similarity or in vitro amplification. However, the latter process may introduce a large amount of noise, thus making it difficult to separate off-target signals from background noise. Whether CRISPR-Cas9 induces off-target effects has been controversial.
