Substantial off-target SNVs generated in BE3-treated mouse embryos. Comparison of the whole-genome sequences of progeny cells of edited and nonedited blastomeres at embryonic day 14.5 showed that off-target single-nucleotide variants (SNVs) were rare in embryos edited by CRISPR-Cas9 or adenine base editor, with a frequency close to the spontaneous mutation rate.

Base editors, which enable production of highly efficient targeted point mutations in genomic DNA without causing double-stranded DNA breaks, hold great promise for gene therapy in human disease and trait improvement in crop plants. In this assay, the orthogonal CRISPR system, nSaCas9, was used to create ssDNA regions in plant cells that acted as targets for sgRNA-independent deamination changes.

These spurious-deamination-minimized CBEs (BE4 with either RrA3F, AmAPOBEC1, SsAPOBEC3B, or PpAPOBEC1) were further optimized for superior on- and off-target DNA editing profiles through structure-guided mutagenesis of the deaminase domain.

The research was mainly supported by the National Transgenic Science and Technology Program, the Strategic Priority Research Program of the Chinese Academy of Sciences, and the National Natural Science Foundation of China. Recently, the foundational cytosine base editor (CBE) ‘BE3’, containing rAPOBEC1, was reported to induce unguided, genomic DNA3, 4 and cellular RNA5 cytosine deamination when expressed in living cells. 2019 May;29(5):339-340. doi: 10.1038/s41422-019-0159-2. In this way, they obtained two new CBE variants, A3Bctd-VHM-BE3 and A3Bctd-KKR-BE3, which exhibited efficient on-target activity and markedly reduced sgRNA-independent off-target activity. | Xie J, Huang X, Wang X, Gou S, Liang Y, Chen F, Li N, Ouyang Z, Zhang Q, Ge W, Jin Q, Shi H, Zhuang Z, Zhao X, Lian M, Wang J, Ye Y, Quan L, Wu H, Wang K, Lai L.

Copyright © 2019 The Authors, some rights reserved; exclusive licensee American Association for the Advancement of Science. Two studies in Science show that cytosine base editors, but not adenine base editors or CRISPR–Cas9, induce notable off-target single-nucleotide variants in rice and in mouse embryos. Also, they validated the high specificity of A3Bctd-VHM-BE3 and A3Bctd-KKR-BE3 by WGS assay. Please enable it to take advantage of the complete set of features! Biochemistry.

CRISPR- Cas9–, BE3-, or ABE7.10-mediated gene editing in one blastomere of two-cell embryos. Competing interests: The authors declare no competing financial interests. 2.. The consistent results indicate that the nSaCas9-mediated orthogonal R-loop assay provides a logical, rapid and high-throughput method for assessing the sgRNA-independent off-target activities of CBEs. 2019 Sep 10;58(36):3727-3734. doi: 10.1021/acs.biochem.9b00573. They tested these A3Bctd-BE3 variants using the R-loop assay and selected seven mutations associated with efficient on-target editing activity and reduced off-target activity. Two classes of base editors--cytosine base editors (CBEs) and adenine base editors (ABEs)--can be used to generate single base pair edits without double stranded breaks. Epub 2019 Apr 18.
