WebMay 24, 2024 · After the initial development of a cytosine base editor (CBE) for human cells in 2016, an adenine base editor (ABE) rapidly followed along with novel engineered deaminase and Cas variants that reduce off-target RNA editing and improve editing efficiency (see timeline in Figure 1).This rapid technological development manifested in … WebJul 11, 2024 · Adenine base editors (ABEs) are novel genome-editing tools, and their activity has been greatly enhanced by eight additional mutations, thus named ABE8e. However, elevated catalytic activity was concomitant with frequent generation of bystander mutations. This bystander effect precludes its safe applications required in human gene therapy.
