CRISPR/Cas9基因编辑系统在肿瘤研究中的应用进展

TCRISPR/Cas9 (Clustered Regularly Interspaced Short Palindromic Repeat/CRISPR-associated nuclease 9) gene editing system is a new type of gene editing technology developed based on the immune mechanism of archaea resisting the invasion of exogenous nucleic acid. Compared with traditional gene editing system, CRISPR/Cas9 system is more efficient, easier operating, and less cytotoxic. Currently, CRISPR/Cas9 gene editing technology has been applied to many aspects of cancer research, including research on cancer genes, constructing animal tumor models, screening tumor resistance-associated and phenotypic-related genes and cancer gene therapy. In this review, the application of the CRISPR/Cas9 system in tumor research were introduced.
