Abstract

Angiogenesis, in which vascular endothelial growth factor receptor (VEGFR) 2 plays an essential role, is associated with a variety of human diseases including proliferative diabetic retinopathy and wet age-related macular degeneration. Here we report that a system of adeno-associated virus (AAV)-mediated clustered regularly interspaced short palindromic repeats (CRISPR)-associated endonuclease (Cas)9 from Streptococcus pyogenes (SpCas9) is used to deplete VEGFR2 in vascular endothelial cells (ECs), whereby the expression of SpCas9 is driven by an endothelial-specific promoter of intercellular adhesion molecule 2. We further show that recombinant AAV serotype 1 (rAAV1) transduces ECs of pathologic vessels, and that editing of genomic VEGFR2 locus using rAAV1-mediated CRISPR/Cas9 abrogates angiogenesis in the mouse models of oxygen-induced retinopathy and laser-induced choroid neovascularization. This work establishes a strong foundation for genome editing as a strategy to treat angiogenesis-associated diseases.

  • Recent efforts to address the problem of frequent intravitreal injections have employed gene editing strategies like targeting VEGFA using CRISPR-Cas9.

    “Recent efforts to address this problem have employed gene editing strategies like targeting VEGFA using CRISPR-Cas9 (43, 45).”

    From Characterization of RNA editing and gene therapy with a compact CRISPR-Cas13 in the retina (2024) · cites this paper as [45]

    The Introduction and Discussion describe AAV-mediated CRISPR-Cas9 editing as a potential alternative to anti-VEGF treatment that requires chronic administration. But this study edits genomic VEGFR2, not VEGFA; the claimed target is incorrect. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • A study delivering Cas9 and gRNA targeting VEGFR2 in AAV1 by intravitreal injection to WT C57BL/6J mice reported no damage to the retina four weeks post-injection.

    “A study aimed to use genome editing to treat angiogenesis-associated diseases by packaging Cas9 and gRNA targeting vascular endothelial growth factor receptor 2 (VEGFR2) in AAV1 and delivering it by intravitreal injections to the eye of WT C57BL/6J mice.They analyzed toxicity and inflammation by imaging the fundus as well as immunolabeling the retina for inflammation markers but reported no damage”

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.
