Base editing systems show their power in modeling and correcting the pathogenic mutations of genetic diseases. Previous studies have already demonstrated the editing efficiency of BE3-mediated C-to-T conversion in human embryos. However, the precision and efficiency of a recently developed adenine base editor (ABE), which converts A-to-G editing in human embryos, remain to be addressed. Here we selected reported pathogenic mutations to characterize the ABE in human tripronuclear embryos. We foun...

RNA splicing is related to many human diseases; however, lack of efficient genetic approaches to modulate splicing has prevented us from dissecting their functions in human diseases. Recently developed base editors (BEs) offer a new strategy to modulate RNA splicing by converting conservative splice sites, but it is limited by the editing precision and scope. To overcome the limitations of currently available BE-based tools, we combined SpCas9-NG with ABE-max to generate a new BE, ABEmax-NG. We ...

A recently developed adenine base editor (ABE) efficiently converts A to G and is potentially useful for clinical applications. However, its precision and efficiency in vivo remains to be addressed. Here we achieve A-to-G conversion in vivo at frequencies up to 100% by microinjection of ABE mRNA together with sgRNAs. We then generate mouse models harboring clinically relevant mutations at Ar and Hoxd13, which recapitulates respective clinical defects. Furthermore, we achieve both C-to-T and A-to...

There are urgent demands for efficient treatment of heritable genetic diseases. The base editing technology has displayed its efficiency and precision in base substitution in human embryos, providing a potential early-stage treatment for genetic diseases. Taking advantage of this technology, we corrected a Marfan syndrome pathogenic mutation, FBN1 T7498C . We first tested the feasibility in mutant cells, then successfully achieved genetic correction in heterozygous human embryos. The results sho...

Although CRISPR/Cas9 has been widely used to generate knockout mice, two major limitations remain: the founders usually carry a mixture of genotypes, and mosaicism harboring multiple genotypes. Therefore, it takes a long time to get homozygous mutants. Recently developed base editing (BE) system, which introduces C-to-T conversion without double strand DNA cleavage, has been used to introduce artificial stop codons (i-STOP) to prematurely terminate translation, providing a cleaner strategy for g...

Base editor (BE), containing a cytidine deaminase and catalytically defective Cas9, has been widely used to perform base editing. However, the narrow editing window of BE limits its utility. Here, we developed a new editing technology named as base editor for programming larger C to U (T) scope (BE-PLUS) by fusing 10 copies of GCN4 peptide to nCas9(D10A) for recruiting scFv-APOBEC-UGI-GB1 to the target sites. The new system achieves base editing with a broadened window, resulting in an increased...
