摘要
Drug resistance is a major problem faced by tumor cell-targeted drugs.Currently,functional gene screening is the most common strategy for screening drug resistance genes.In recent years,Crispr-cas9 gene editing technology has been widely used in the functional studies of tumor-related genes due to their characteristics of accuracy,simplicity and efficiency.The principle of CRISPR-Cas9 Library Screening Technology and its application in functional Gene Screening are reviewed.At the same time,the application prospect of the Crispr-Cas9 technology is forecasted.
