Abstract

In conjunction with histone modifications, DNA methylation plays critical roles in gene silencing through chromatin remodeling. Changes in DNA methylation perturb neuronal function, and mutations in a methyl-CpG–binding protein, MeCP2, are associated with Rett syndrome. We report that increased synthesis of brain-derived neurotrophic factor (BDNF) in neurons after depolarization correlates with a decrease in CpG methylation within the regulatory region of the Bdnf gene. Moreover, increased Bdnf transcription involves dissociation of the MeCP2–histone deacetylase–mSin3A repression complex from its promoter. Our findings suggest that DNA methylation–related chromatin remodeling is important for activity-dependent gene regulation that may be critical for neural plasticity.

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?

  • Increased CpG methylation in the promoter region of the BDNF gene correlates with decreased BDNF synthesis in neurons.

    “increased CpG methylation in the promoter region of the gene encoding brain-derived neurotrophic factor (BDNF) has been found to correlate with a decreased synthesis of BDNF in neurons.53”
  • MeCP2 acts as a bridge between DNA methylation marks and HDACs, enzymes involved in histone modifications.

    “MeCP2 is known to act as a bridge between DNA methylation marks and HDACs, enzymes involved in histone modifications and has been shown to dock at CpG-methylated sites and recruit HDACs to the chromatin, forming a silencing complex that represses gene transcription (Martinowich et al., 2003).”
  • MeCP2 binding to chromatin is partially impaired if CpG sites are hypomethylated.

    “This binding is partially impaired if CpG sites are hypomethylated (Martinowich et al., 2003).”
  • MeCP2 docks at CpG-methylated sites and recruits HDACs to the chromatin, forming a silencing complex that represses gene transcription.

    “MeCP2 is known to act as a bridge between DNA methylation marks and HDACs, enzymes involved in histone modifications and has been shown to dock at CpG-methylated sites and recruit HDACs to the chromatin, forming a silencing complex that represses gene transcription (Martinowich et al., 2003).”
  • Following depolarization of mouse embryonic day 15 (E14) cortical cells, MeCP2 was partially dissociated from the Bdnf promoter.

    “Following depolarization of mouse embryonic day 15 (E14) cortical cells, MeCP2 was found to be partially dissociated from the Bdnf promoter, suggesting that neuronal firing may redistribute MeCP2 binding allowing for BDNF expression (Martinowich et al., 2003).”

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.
