Dear Editor Rats are reference laboratory animal models for understanding mechanism of human diseases such as diabetes, hypertension, and neurological disorder 1, 2. CRISPR/Cas9 system has proved an efficient and flexible tool to generate gene modified rats 3–6. Great efforts have been made to reduce the side effects and extend the application of this system 7–10. Cytosine base editor (CBE), containing the engineered cytosine deaminase with CRISPR/Cas9 can be used to modify mammal genomic DNA without induction of double-strand DNA break or template. CBE targets sequence by inducing C· G to T· A conversion with a window of approximately five nucleotides 11. Recently, the same group developed a new dCas9-guide tRNA adenosine deaminase which was capable of inducing A· T to G· C conversion. Together with CBE, ABE enables introduction of all four nucleotides transitions (C to T, A to G, T to C, and G to A) in target genomic sequence 12. These base-editing tools provide a much safer approach compared with wild-type CRISPR/Cas9 system for gene correction of human disease. Here we report the application of this newly developed adenine base editors in rat base editing.
