Abstract

Significance: Although understanding the precise nature of oxytocin’s influence on complex human social behavior has proven difficult, increasing evidence points to an anxiolytic effect. We use an imaging epigenetic approach to further parse oxytocin’s effects by examining a biological marker within the oxytocin system, DNA methylation of the oxytocin receptor gene ( OXTR ). Importantly, this epigenetic modification directly impacts the expression of oxytocin’s receptor, which is critical for the actions of oxytocin to have an effect. We find that higher levels of OXTR methylation are associated with increased neural response and decreased functional coupling within regions supporting social perception and emotion processing. This pattern of activity may be indicative of diminished emotion regulation to negative stimuli and increased risk of pathology.

  • The STS result aligns with oxytocin increasing STS activity in autism and with OXTR methylation relating to STS activity.

    “The current finding is consistent with a prior neuroimaging study demonstrating that oxytocin administration enhances STS activity in individuals with autism (37), and with a recent finding that OXTR methylation is associated with STS activity (6).”
  • Methylation of OXTR in peripheral blood cells is associated with decreased correlated fluctuations in BOLD responses among limbic and cortical regions while viewing fearful and angry faces.

    “Two studies have shown that naturally-occurring polymorphisms in human OXTR (the gene encoding OTR) are associated with correlated fluctuations in BOLD responses between hypothalamic, limbic, and/or cortical brain areas during social tasks (Tost et al., 2010; Tost et al., 2011), and one has shown that methylation of OXTR in peripheral blood cells is associated with decreased correlated fluct”

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.
