Abstract

Efforts to manipulate locus-specific histone acetylation to assess their causal role in gene expression and cellular and behavioural phenotypes have been impeded by a lack of experimental tools. The Cas9 nuclease has been adapted to target epigenomic modifications, but a detailed description of the parameters of such synthetic epigenome remodellers is still lacking. Here we describe a Cas9-based histone deacetylase (HDAC) and the design principles required to achieve locus-specific histone deacetylation. We assess its range of activity and specificity, and analyse target gene expression in two different cell types to investigate cellular context-dependent effects. Our findings demonstrate that the chromatin environment is an important element to consider when utilizing this synthetic HDAC.

  • Additional dCas9-tethered domains have been shown to disrupt enhancer activity.

    “Additional dCas9-tethered domains have been shown to disrupt enhancer activity (e.g. histone demethylase LSD1210, histone deacetylase 3211, and DNA methylators MQ212 or DNMT3A213-215), and could potentially be adapted to large-scale screens.”

    From Towards a comprehensive catalogue of validated and target-linked human enhancers (2020) · cites this paper as [211]

    The Results show that dCas9-HDAC3 can reduce gene expression when targeted appropriately at promoters. The Discussion explicitly says future work is needed to determine whether it can affect gene expression when positioned at enhancers, contrary to the claim that enhancer disruption had been shown.

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.
