ABSTRACT
The CRISPR system is able to accomplish precise base editing in genomic DNA, but relies on the cellular homology-directed recombination repair pathway and is therefore extremely inefficient. Base editing is a new genome editing technique developed based on the CRISPR/Cas9 system. Two base editors (cytosine base editor and adenine base editor) were developed by fusing catalytically disabled nucleases with different necleobase deaminases. These two base editors are able to perform C>T (G>A) or A>G (T>C) transition without generating DNA double-stranded breaks. The base editing technique has been widely used in gene therapy, animal models construction, precision animal breeding and gene function analysis, providing a powerful tool for basic and applied research. This review summarized the development process, technical advantages, current applications, challenges and perspectives for base editing technique, aiming to help the readers better understand and use the base editing technique.
