Project description:Even the latest generation of base editor (BE3) causes unwanted indels and non-C-to-T substitutions, compromising the fidelity of base editing outcome. Here we report a enhanced base editing system. The enhanced base edting system decreased the formation of unintended indels and C-to-A/C-to-G substitutions, and increased the frequency of desired C-to-T substitution, thereby improving both the accuracy and efficiency of base editing.

Project description:Mitochondrial base editing sequencing
Project description:The goal of these experiments were to test the on-target and target-adjacent editing efficiencies of different single-nucleobase editing systems. Previous studies have shown that tethering DNA mutating enzymes to Cas9-nickase-UGI complexes results in editing of chromosomal DNA. However, these editing events encompass undesirable target-adjacent nucleobase edits. Here, we characterize a novel approach that reduces the frequency of target-adjacent editing while maintaining a high level of on-target editing.
