Abstract

The discovery of clustered regularly interspaced short palindromic repeats (CRISPR) genome editing technology opened the door to provide a versatile approach for treating multiple diseases. Promising results have been shown in numerous pre-clinical studies and clinical trials. However, a safe and effective method to deliver genome-editing components is still a key challenge for in vivo genome editing therapy. Adeno-associated virus (AAV) is one of the most commonly used vector systems to date, but immunogenicity against capsid, liver toxicity at high dose, and potential genotoxicity caused by off-target mutagenesis and genomic integration remain unsolved. Recently developed transient delivery systems, such as virus-like particle (VLP) and lipid nanoparticle (LNP), may solve some of the issues. This review summarizes existing in vivo delivery systems and possible solutions to overcome their limitations. Also, we highlight the ongoing clinical trials for in vivo genome editing therapy and recently developed genome editing tools for their potential applications.

  • The activity and fidelity of gene editing is heavily affected by the expression level and duration of the editors in the cells.

    “The activity and fidelity of gene editing is heavily affected by the expression level and duration of the editors in the cells.”

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

    Section 6.4 states that off-target mutagenesis risk depends on the level and duration of Cas9/gRNA expression, supporting the fidelity part of the claim. Section 3.7 discusses expression duration and editing kinetics, but says short-lived editors are usually sufficient for lasting effects; it does not establish that editing activity is heavily affected by both expression level and duration across editors. Page numbers are unavailable in our copy. (LLM, conf=0.83)

  • Methods to deliver Cas9/sgRNA into target cells profoundly influence its off-target effect.

    “Therefore, methods to deliver Cas9/sgRNA into the target cells profoundly influence its off-target effect”

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.
