Abstract

The mechanism of action of electroconvulsive seizures (ECS), one of the most effective treatments of major depression, may involve the regulation of gene expression. Chromatin remodeling at gene promoter regions is increasingly recognized as a key control point of gene expression and may, therefore, partly mediate acute and chronic effects of ECS on gene activity. Here, we assayed how posttranslational modifications of histones, a major form of chromatin remodeling, are altered at several gene promoters in rat hippocampus at 30 min, 2 hr, and 24 hr after acute or repeated ECS. We performed chromatin immunoprecipitation assays to measure levels of histone H3 and H4 acetylation and phosphoacetylation at the promoters of the c-fos, BDNF, and CREB (cAMP response element-binding protein) genes, the expression of which is altered by ECS. We found that, with few exceptions, levels of H4 acetylation correlated with mRNA levels for c-fos, BDNF, and CREB throughout the acute and chronic time course study, whereas acetylation and phosphoacetylation of H3 were detected more selectively. Our findings suggest that the chronic downregulation of c-fos transcription, observed in this study, may be achieved at the level of H4 acetylation, whereas chronic upregulation of BDNF transcription may be sustained via control of H3 acetylation, selectively at the BDNF P3 and P4 promoters. These data provide the first in vivo demonstration of the involvement of chromatin remodeling in ECS-induced regulation of gene expression in the brain and will help in understanding the mechanisms underlying the efficacy of ECS in the treatment of depression.

  • In depression mice models, abnormal energy metabolism features have been documented, including abnormal glucose metabolism, elevated lactate levels, mitochondrial dysfunction, and abnormal ATP levels.

    “In the depression mice model, features of abnormal energy metabolism have also been documented, including abnormal glucose metabolism, elevated lactate levels, mitochondrial dysfunction, and abnormal ATP levels [19–22].”

    The Introduction and Discussion describe histone modifications and gene expression after electroconvulsive seizures in rat hippocampus, not energy metabolism in depression mouse models. Searches for glucose metabolism, lactate, mitochondrial dysfunction, ATP, and energy metabolism found no passage addressing those features. Page numbers were not available in our copy.

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.
