Abstract

Methods for sensitive and high-throughput evaluation of CRISPR RNA-guided nucleases (RGNs) off-targets (OTs) are essential for advancing RGN-based gene therapies. Here we report SURRO-seq for simultaneously evaluating thousands of therapeutic RGN OTs in cells. SURRO-seq captures RGN-induced indels in cells by pooled lentiviral OTs libraries and deep sequencing, an approach comparable and complementary to OTs detection by T7 endonuclease 1, GUIDE-seq, and CIRCLE-seq. Application of SURRO-seq to 8150 OTs from 110 therapeutic RGNs identifies significantly detectable indels in 783 OTs, of which 37 OTs are found in cancer genes and 23 OTs are further validated in five human cell lines by targeted amplicon sequencing. Finally, SURRO-seq reveals that thermodynamically stable wobble base pair (rG•dT) and free binding energy strongly affect RGN specificity. Our study emphasizes the necessity of thoroughly evaluating therapeutic RGN OTs to minimize inevitable off-target effects.

  • CIRCLE-seq can detect genome-wide off-target sites without performing WGS.

    “CIRCLE-seq is another method that can detect genome-wide off-target sites without performing WGS.”

    From Off-target effects in CRISPR/Cas9 gene editing (2023) · cites this paper as Pan et al., 2022

    The References identify CIRCLE-seq as a genome-wide CRISPR-Cas9 off-target screen, and the Results describe it detecting off-target sites through cleavage of cell-free DNA. Our copy does not state whether CIRCLE-seq avoids whole-genome sequencing, so it does not establish that part of the claim. (LLM, conf=0.80)

  • A primary limitation of GUIDE-seq is the low delivery efficiency of dsODNs into cells, resulting in detection of only 30%-50% of all DSBs.

    “A primary limitation of GUIDE-seq is relevant to the low delivery efficiency of dsODNs into cells, which results in detection of only 30%–50% of all the DSBs (Tsai et al., 2015; Pan et al., 2022).”

    From Off-target effects in CRISPR/Cas9 gene editing (2023) · cites this paper as Pan et al., 2022

    The Introduction (page unavailable) says GUIDE-seq relies on inserting double-stranded DNA at double-strand breaks, and the Results section on SURRO-seq validation likewise describes insertion of a double-stranded oligonucleotide. Neither passage says that delivery into cells is inefficient or that GUIDE-seq detects only 30%–50% of DSBs; searches for those terms found no such estimate in our copy. (LLM, conf=0.84)

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.
