Rescue of Recombinant Adenoviruses by CRISPR/Cas-Mediated in vivo Terminal Resolution.

ABSTRACT: Recombinant adenovirus (rAd) vectors represent one of the most frequently used vehicles for gene transfer applications in vitro and in vivo. rAd genomes are constructed in Escherichia coli where their genomes can be maintained, propagated, and modified in form of circular plasmids or bacterial artificial chromosomes. Although the rescue of rAds from their circular plasmid or bacmid forms is well established, it works with relatively low primary efficiency, preventing this technology for library applications. To overcome this barrier, we tested a novel strategy for the reconstitution of rAds that utilizes the CRISPR/Cas-machinery to cleave the circular rAd genomes in close proximity to their inverted terminal repeats (ITRs) within the producer cells upon transfection.
