Abstract
Clustered regularly interspaced short palindromic repeats (CRISPR-Cas9) has been the most practical technique in genome editing for the last decade. Its molecular mechanism includes steps that occur in a sequence, starting from a break in a double strand to repair. After a double-strand break in the DNA strand, the repairing of DNA done via Homology-Directed Repair (HDR) is considered important in different organisms as it is ideal for precise genome editing and the reduction of unintended mutations. Still, it is mostly dominated by the Non-Homologous End Joining (NHEJ) pathway. A recent study by Cullot et al. published in Nature Biotechnology showed interesting features of AZD7648 (a DNA-PKcs inhibitor) that increase the probability of HDR event while DNA repairing (Cullot et al. 2024).
期刊介绍：
Functional & Integrative Genomics is devoted to large-scale studies of genomes and their functions, including systems analyses of biological processes. The journal will provide the research community an integrated platform where researchers can share, review and discuss their findings on important biological questions that will ultimately enable us to answer the fundamental question: How do genomes work?
