Fig. 3. Next-generation CBEs with reduced RNA off-target editing efficiency relative to BE4 in mammalian cells.
Transcriptome-wide mRNA sequencing (a) and targeted RNA sequencing (b) of HEK293T cells expressing next-generation CBEs. Base editing efficiencies were reported for the most edited base in the target sites. Values in b reflect the mean of n = 2 independent biological replicates. c correlation of the numbers of C-to-U mutations observed in transcriptome-wide mRNA sequencing with percentage of C-to-U conversion in targeted RNA sequencing. Values for x-axis reflect the mean editing efficiency at sites shown in b from n = 2 independent biological replicates. Values for y-axis reflect the mean of n = 3 biological replicates shown in a.
