Abstract

Technologies for engineering synthetic transcription factors have enabled many advances in medical and scientific research. In contrast to existing methods based on engineering of DNA-binding proteins, we created a Cas9-based transactivator that is targeted to DNA sequences by guide RNA molecules. Coexpression of this transactivator and combinations of guide RNAs in human cells induced specific expression of endogenous target genes, demonstrating a simple and versatile approach for RNA-guided gene activation.

  • Because of the relatively large size of 4277 bp of dCas9-VPR cDNA, the authors used a dual rAAV system to express the dCas9-VPR and gRNA expression cassettes.

    “Because of the relatively large size of 4277 bp of dCas9-VPR cDNA, the authors used a dual rAAV system to express the dCas9-VPR and gRNA expression cassettes [223,224].”

    From Recombinant Adeno-Associated Viral Vectors (rAAV)-Vector Elements in Ocular Gene Therapy Clinical Trials and Transgene Expression and Bioactivity Assays (2020) · cites this paper as [223]

    The paper’s Online Methods (Plasmids; Cell culture and transfection, page unavailable) describe a dCas9-VP64 construct and transfection of plasmids encoding dCas9-VP64 and gRNAs, not a dual rAAV system expressing dCas9-VPR. Our copy does not give a 4277-bp dCas9-VPR cDNA size or attribute the delivery method to that size. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • CRISPRi and CRISPRa technologies utilize catalytically inactive Cas9 (dCas9) fused to either a transcriptional repressor (e.g., KRAB) or a transcriptional activator (e.g., VPR).

    “For example, CRISPRi (interference)23–25 and CRISPRa (activation)26–30 technologies utilize catalytically inactive Cas9 (dCas9) fused to either a transcriptional repressor (e.g., KRAB, Krüppel associated box) or a transcriptional activator (e.g., VPR, VP64-p65-Rta).”

    From Large-scale CRISPR screening in primary human 3D gastric organoids enables comprehensive dissection of gene-drug interactions (2025) · cites this paper as [27]

    The paper’s Abstract describes a CRISPR activation system made by fusing catalytically inactive Cas9 to the VP64 transactivation domain. It does not describe the cited VPR activator; its mention of gene silencing concerns steric hindrance, not a dCas9–KRAB repressor. No page number is provided in our copy. (LLM, conf=0.88)

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.
