Abstract

Epigenetic regulation may be involved in the pathophysiology of mental disorders, such as schizophrenia and bipolar disorder, and in the pharmacological action of drugs. Characterizing the epigenetic effects of drugs is an important step to optimal treatment. We performed comprehensive and gene-specific DNA methylation analyses of quetiapine using human neuroblastoma cells. Human neuroblastoma cells were cultured with quetiapine for 8 days, and DNA methylation analysis was performed using Infinium HumanMethylation27 BeadChip. A total of 1173 genes showed altered DNA methylation. Altered DNA methylation predominantly occurred as hypomethylation within the CpG island compared to DNA isolated from non-treated cells. Gene ontology analysis revealed that these genes were related to the cellular process of intracellular protein binding. There was no common effect of quetiapine with three mood stabilizers (lithium, valproate, and carbamazepine). However, common DNA methylation changes in eight genes, including ADRA1A, which encodes adrenoceptor alpha 1A, were found with quetiapine and lithium treatments. Finally, bisulfite-sequencing analysis revealed that quetiapine decreased the DNA methylation level of the promoter region of SLC6A4, where hypermethylation with bipolar disorder and hypomethylation with mood stabilizers have been reported.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Lithium, carbamazepine and quetiapine, often prescribed for bipolar disorder, are associated with decreased methylation of SLC6A4.

    “For example, Lithium, Carbamazepine and Quetiapine, often prescribed for the treatment of BD, are associated with decrease methylation of SLC6A4 (Asai et al., 2013; Sugawara et al., 2015), in contrast with the hypermethylation reported in BD in that gene (Table 2).”

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.
