Abstract

Zinc-finger nucleases (ZFNs) allow gene editing in live cells by inducing a targeted DNA double-strand break (DSB) at a specific genomic locus. However, strategies for characterizing the genome-wide specificity of ZFNs remain limited. We show that nonhomologous end-joining captures integrase-defective lentiviral vectors at DSBs, tagging these transient events. Genome-wide integration site analysis mapped the actual in vivo cleavage activity of four ZFN pairs targeting CCR5 or IL2RG. Ranking loci with repeatedly detectable nuclease activity by deep-sequencing allowed us to monitor the degree of ZFN specificity in vivo at these positions. Cleavage required binding of ZFNs in specific spatial arrangements on DNA bearing high homology to the intended target site and only tolerated mismatches at individual positions of the ZFN binding sites. Whereas the consensus binding sequence derived in vivo closely matched that obtained in biochemical experiments, the ranking of in vivo cleavage sites could not be predicted in silico. Comprehensive mapping of ZFN activity in vivo will facilitate the broad application of these reagents in translational research.

  • An integrase-deficient lentivirus capture assay measures genome wide integration as a way to detect off-target effects in an unbiased manner.

    “Another study used an integrase-deficient lentivirus capture (IDL genome gets inserted at DSBs created by ZFN) assay to measure genome wide integration as a way to detect off-target effects in an unbiased manner.”

  • Proper evaluation of the specificity of any particular ZFN pair will require the use of the relevant cell type, the intended ZFN dose and the delivery method for that specific application.

    “Taken together, these studies highlight the fact that proper evaluation of the specificity of any particular ZFN pair will require the use of the relevant cell type, the intended ZFN dose and the delivery method for that specific application.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
