Abstract

Genome Editing: Clustered regularly interspaced short palindromic repeats (CRISPR) function as part of an adaptive immune system in a range of prokaryotes: Invading phage and plasmid DNA is targeted for cleavage by complementary CRISPR RNAs (crRNAs) bound to a CRISPR-associated endonuclease (see the Perspective by van der Oost ). Cong et al. (p. 819 , published online 3 January) and Mali et al. (p. 823 , published online 3 January) adapted this defense system to function as a genome editing tool in eukaryotic cells.

  • Upon target recognition, the DNA strands are opened in an R-loop and individually cleaved, which results in a DSB.

    “Upon target recognition, the DNA strands are opened in an R-loop and individually cleaved, which results in a double-strand break (DSB)22,23”

    From One-step generation of tumor models by base editor multiplexing in adult stem cell-derived organoids (2023) · cites this paper as [23]

    The main text (page unavailable in our copy) says that a related Cas9 protein cuts both DNA strands near the PAM and reports target-site editing consistent with cleavage. It does not describe DNA strands opening in an R-loop or establish that sequence of events, so the mechanistic detail is unsupported. (LLM, conf=0.87)

  • Mali et al. created a novel version of the genome-editing tool applicable to mammalian cells, termed the CRISPR/Cas9 system, based on modifications of the Streptococcus pyogenes type II CRISPR system in crRNA fused to trans-encoded tracrRNA.

  • Mammalian genomes can be edited by homologous recombination when a double-strand break is introduced and a DNA template with high sequence similarity is provided; an artificial template can incorporate desired DNA sequences.

    “When a double-stranded break is introduced into genomic DNA, cells can repair the break by using a DNA molecule with high sequence similarity as a template. If an artificial template is provided while the DNA break is introduced, this pathway provides a mean to incorporate desired DNA sequences into the genome34,35”

  • A simple two-component system of Streptococcus pyogenes Cas9 bound to a single guide RNA can function as a programmable nuclease that can cleave specific sequences in mammalian genomes.

    “The discovery, made less than 10 years ago, that a simple two-component system of a Cas protein (Streptococcus pyogenes Cas9) bound to a single guide RNA (sgRNA) can function as a programmable nuclease33 that can be deployed to cleave specific sequences in mammalian genomes34,35 has been transformative for biomedical research and the development of gene therapies.”

    From CRISPR-based functional genomics for neurological disease (2020) · cites this paper as [35]

  • The CRISPR/Cas system has been successfully applied to human cells and several model organisms for genome editing.

    “Recently, the CRISPR/Cas system has been successfully applied to human cells19,20,21,22 and several model organisms for genome editing.23,24,25,26”

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.
