Abstract

CRISPR-Cas9–based genetic screens are a powerful new tool in biology. By simply altering the sequence of the single-guide RNA (sgRNA), one can reprogram Cas9 to target different sites in the genome with relative ease, but the on-target activity and off-target effects of individual sgRNAs can vary widely. Here, we use recently devised sgRNA design rules to create human and mouse genome-wide libraries, perform positive and negative selection screens and observe that the use of these rules produced improved results. Additionally, we profile the off-target activity of thousands of sgRNAs and develop a metric to predict off-target sites. We incorporate these findings from large-scale, empirical data to improve our computational design rules and create optimized sgRNA libraries that maximize on-target activity and minimize off-target effects to enable more effective and efficient genetic screens and genome engineering.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • CRISPR/Cas9 can identify genes related to drug resistance in cancer cells and facilitate research on overcoming this resistance.

    “Additionally, it can identify genes related to drug resistance in cancer cells and facilitate research on overcoming this resistance [8].”

    From A Review of Research on CRISPR/Cas9 Gene Editing Technology in Disease Treatment (2024) · cites this paper as [8]

    The Results section (“Genetic screens with the Avana and Asiago libraries”; page unavailable) reports CRISPR screens in melanoma cells that identified and validated genes associated with resistance to vemurafenib. The Discussion says improved sgRNA design will facilitate further screening, but our copy does not specifically address research on overcoming drug resistance. (LLM, conf=0.82)

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.
