Article Title: Double-Strand Break Repair Pathways Differentially Affect Processing and Transduction by Dual AAV Vectors
doi: 10.1101/2023.09.19.558438
Figure Lengend Snippet: (A) Early in transduction, rAAV vector genomes quickly associate with histones and are marked as double-strand breaks (DSB) by the host cell as evidenced by staining for ψH2AX. (B) HDR machinery appears to be recruited first (as detected with antibodies to BRCA1 and Rad51), which may block successful recruitment of NHEJ factors (such as DNA-PK and 53BP1). (C) Inhibition or loss of HDR machinery promotes increased expression and concatenation, which synergize to increase dual vector transduction.
