Abstract

Cocaine Addiction and Histone Methylation: Long-lasting behavioral syndromes associated with chronic cocaine exposure may result from dysregulation of the global transcriptional machinery. Maze et al. (p. 213 ) observed that histone lysine methylation in the nucleus accumbens plays a critical role in mediating the regulation of gene expression in response to repeated cocaine self-administration. Chronic cocaine was linked to overall reductions in dimethylation of lysine 9 of histone 3 (H3K9) in this brain region. Repressing H3K9 after chronic cocaine administration facilitated reward-related changes in behavior. The authors identifed the methyltransferase G9a as an essential mediator and an important regulator of dendritic spine plasticity. Downregulation of G9a was linked to the transcription factor ΔFosB.

  • Manipulation of enzymes that control histone acetylation or deacetylation or DNA methylation in the nucleus accumbens modifies drug behavioral responses, supporting their relevance to drug reward and SUDs.

    “Moreover, the manipulation of enzymes that control histone acetylation or deacetylation or DNA methylation in the nucleus accumbens modifies drug behavioral responses, supporting their relevance to drug reward and SUDs 111,112 .”

    From Substance use disorders: a comprehensive update of classification, epidemiology, neurobiology, clinical aspects, treatment and prevention (2023) · cites this paper as [111]

    The paper reports that manipulating G9a in the nucleus accumbens changes cocaine preference (passage 5, section labeled Abstract). But G9a controls histone methylation, not histone acetylation, deacetylation, or DNA methylation. The paper mentions histone acetylation as background (passage 1), without showing the enzyme manipulations specified in the claim. (LLM, conf=0.84)

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.
