Engineering of cytosine base editors with DNA damage minimization and editing scope diversification
Abstract Cytosine base editors (CBEs), which enable precise C-to-T substitutions, have been restricted by potential safety risks, including DNA off-target edits, RNA off-target edits and additional genotoxicity such as DNA damages induced by double-strand breaks (DSBs).

Genome- and transcriptome-wide off-target analyses of an improved cytosine base editor
Abstract Cytosine base editors (CBEs) are the promising tools for precise genome editing in plants. It is important to investigate potential off-target effects of an efficient CBE at the genome and transcriptome levels in a major crop. Based on comparison of five cytidine deaminases and two different promoters for expressing single-guide

Genome sequencing of the extinct Eurasian wild aurochs, Bos primigenius, illuminates the phylogeography and evolution of cattle [PDF]
Background Domestication of the now-extinct wild aurochs, Bos primigenius, gave rise to the two major domestic extant cattle taxa, B. taurus and B. indicus.

Computer simulations explain mutation-induced effects on the DNA editing by adenine base editors. [PDF]
Adenine base editors, which were developed by engineering a transfer RNA adenosine deaminase enzyme (TadA) into a DNA editing enzyme (TadA*), enable precise modification of A:T to G⋮C base pairs. Here, we use molecular dynamics simulations to uncover the

Engineered Sdd7 cytosine base editors with enhanced specificity
Cytosine base editors (CBEs) revolutionize genome editing by enabling precise C-to-T conversions without double-strand breaks. Sdd7, a recently developed cytosine deaminase, exhibits high activity across a broad protospacer range but induces unintended off-target effects, including bystander mutations within and upstream of the protospacer and both ...

ACBE, a new base editor for simultaneous C-to-T and A-to-G substitutions in mammalian systems
Background Many favorable traits of crops and livestock and human genetic diseases arise from multiple single nucleotide polymorphisms or multiple point mutations with heterogeneous base substitutions at the same locus.

CABE-RY: A PAM-flexible dual-mutation base editor for reliable modeling of multi-nucleotide variants
Multi-nucleotide variants (MNVs) represent an important type of genetic variation and have biological and clinical significance. To simulate MNVs, we designed four dual-mutation base editors combining hA3A(Y130F), TadA8e(V106W), and protospacer adjacent ...
