Abstract

Genome editing offers promising solutions to genetic disorders by editing DNA sequences or modulating gene expression. The clustered regularly interspaced short palindromic repeats (CRISPR)/associated protein 9 (CRISPR/Cas9) technology can be used to edit single or multiple genes in a wide variety of cell types and organisms in vitro and in vivo. Herein, we review the rapidly developing CRISPR/Cas9-based technologies for disease modeling and gene correction and recent progress toward Cas9/guide RNA (gRNA) delivery based on viral and nonviral vectors. We discuss the relative merits of delivering the genome editing elements in the form of DNA, mRNA, or protein, and the opportunities of combining viral delivery of a transgene encoding Cas9 with nonviral delivery of gRNA. We highlight the lessons learned from nonviral gene delivery in the past three decades and consider their applicability for CRISPR/Cas9 delivery. We also include a discussion of bioinformatics tools for gRNA design and chemical modifications of gRNA. Finally, we consider the extracellular and intracellular barriers to nonviral CRISPR/Cas9 delivery and propose strategies that may overcome these barriers to realize the clinical potential of CRISPR/Cas9-based genome editing.

Claims other papers make about this one

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

  • The CRISPR-Cas9 system can be designed to edit a large number of sequences in the genome with different sgRNAs and donor DNA templates.

    “The system can be designed to edit a large number of sequences in the genome with different sgRNAs and donor DNA templates, thus making it a powerful genome editing tool.[202, 205, 207]”
  • The complexity and large molecular weight of genome editing components are significant challenges for delivery materials.

    “Secondly, the complexity and large molecular weight of these components are significant challenges for delivery materials.”
  • The Cas9 nuclease utilizes a sgRNA to recognize the target sequence and subsequently cleaves the genome at the specific site.

    “The Cas9 nuclease utilizes a sgRNA to recognize the target sequence and subsequently cleaves the genome at the specific site.”
  • Genome editing components must reach the cell nucleus to achieve therapeutic effects, requiring overcoming extracellular and intracellular barriers including enzymatic degradation in blood, RES clearance, cell membrane penetration, endosome escape, and nuclear membrane infiltration.

    “Firstly, genome editing components must reach the cell nucleus to achieve therapeutic effects. Thus, extracellular and intracellular barriers need to be overcome, including avoiding enzymatic degradation in the blood, circumventing clearance by the reticuloendothelial system (RES), penetrating cell membranes, escaping endosome entrapment, and infiltrating nuclear membranes.”
  • Non-viral materials for delivery of genome editing tools are similar to those used for mRNA delivery.

    “These materials are similar to those used for mRNA delivery.[202, 205, 207–211]”

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.
