Abstract

We recently demonstrated that the potent hallucinogenic drug lysergic acid diethylamide (LSD) dynamically influences the expression of a small collection of genes within the mammalian prefrontal cortex. Towards generating a greater understanding of the molecular genetic effects of hallucinogens and how they may relate to alterations in behavior, we have identified and characterized expression patterns of a new collection of three genes increased in expression by acute LSD administration. These genes were identified through additional screens of Affymetrix DNA microarrays and examined in experiments to assess dose–response, time course and the receptor mediating the expression changes. The first induced gene, C/EBP‐β, is a transcription factor. The second gene, MKP‐1, suggests that LSD activates the MAP (mitogen activated protein) kinase pathway. The third gene, ILAD‐1, demonstrates sequence similarity to the arrestins. The increase in expression of each gene was partially mediated through LSD interactions at 5‐HT 2A (serotonin) receptors. There is evidence of alternative splicing at the ILAD‐1 locus. Furthermore, data suggests that various splice isoforms of ILAD‐1 respond differently at the transcriptional level to LSD. The genes thus far found to be responsive to LSD are beginning to give a more complete picture of the complex intracellular events initiated by hallucinogens.

  • Findings from in vivo studies investigating acute effects of a single dose of 5-MeO-DMT, DMT, psilocybin, and LSD (37%) suggest altered cellular plasticity of structural and functional nature.

    The Discussion (pp. 581–583) reports acute LSD-induced expression of genes associated with synaptic plasticity, and the paper suggests these changes could have longer-term neuromodulatory effects. It does not demonstrate structural or functional plasticity after LSD; it measures gene expression. This source addresses LSD, not the other drugs grouped with it in the multi-citation sentence. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • A single dose of LSD (0.20, 0.24, 0.5, 1.0 mg/kg i.p.) stimulated the mRNA expression of plasticity-promoting genes in the cortex of rats and mice, within 1-2 h after administration and in a time- and dose-dependent manner.

    The Animals, Dose-response, and Time course sections (page numbers not provided) describe single-dose LSD experiments in rat prefrontal cortex at 0.2, 0.5, and 1.0 mg/kg, with dose-dependent expression and peaks at 45 or 90 minutes. The paper does not report mouse experiments or a 0.24 mg/kg dose. It describes the genes as implicated in synaptic plasticity, but does not establish that their increased expression promotes plasticity. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Preclinical evidence suggests a dose-dependent effect on increases in the expression of some neuroplasticity-related genes induced by serotonergic psychedelics.

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.
