Abstract

Depression is associated with alterations in hypothalamic-pituitary-adrenal (HPA) axis activity. A proposed mechanism to explain these alterations are changes in DNA methylation levels, secondary to early life adversity (ELA), at stress-related genes. Two gene regions that have been implicated in the literature, the glucocorticoid receptor gene (NR3C1) exon 1F and the FKBP5 gene intron 7 were examined in 67 individuals (33 depressed patients and 34 controls). We investigated whether cortisol concentrations, evaluated in 25 depressed patients and 20 controls, and measures of ELA were associated with the degree of methylation at these candidate gene regions. Mean NR3C1 exon 1F DNA methylation levels were significantly increased in the depressed cohort and the degree of methylation was found to be positively associated with morning cortisol concentrations. DNA methylation levels at specific CG sites within the NR3C1 exon 1F were related to childhood emotional abuse severity. DNA methylation at CG38 was related to both HPA axis and childhood emotional abuse measures in the depressed group. No FKBP5 differences were revealed. Our findings suggest that hypermethylation at the NR3C1 exon 1F may occur in depression. This locus-specific epigenetic change is associated with higher basal HPA axis activity, possibly reflecting acquired glucocorticoid receptor resistance.

  • Mean exon 1F methylation and NGFI-A binding site methylation positively correlate with increased morning cortisol levels and average morning cortisol output in depressed patients.

    “mean exon 1 F methylation and NGFI-A binding site methylation positively correlated with increased levels of morning cortisol levels and average morning cortisol output in depressed patients (Farrell et al., 2018)”

    From The applied implications of epigenetics in anxiety, affective and stress-related disorders - A review and synthesis on psychosocial stress, psychotherapy and prevention (2020) · cites this paper as Farrell et al., 2018

    Table 5 (p. 27) reports positive correlations of CG38 methylation, at the NGFI-A binding site, with both waking cortisol and average morning cortisol output. Mean exon 1F methylation correlates significantly with average morning output, but not waking cortisol (p=0.12). These correlations were calculated across all participants, not specifically depressed patients. (LLM, conf=0.90)

  • At the level of NR3C1 there is consistent evidence on a positive correlation between childhood adversity and DNAm in Borderline PD and MDD and some clinical outcomes, and a negative correlation with anxiety and PTSD.

    “at the level of NR3C1 there is consistent evidence on a positive correlation between CA and DNAm in Borderline PD and MDD and some clinical outcomes (Farrell et al., 2018; Martin-Blanco et al., 2014; Perroud et al., 2011; Radtke et al., 2015), and a negative correlation with anxiety and PTSD (Labonte, Azoulay, Yerko, Turecki, & Brunet, 2014; Schechter et al., 2015; Wang et al., 2017; Yehuda et al.”

    From Can epigenetics shine a light on the biological pathways underlying major mental disorders? (2022) · cites this paper as Farrell et al., 2018

    The Results (p. 13) report a positive association between childhood emotional abuse severity and methylation at two NR3C1 exon 1F sites, but only among depressed participants who reported early-life adversity. The paper does not establish the broader claim for childhood adversity generally: it found no association with the other forms of adversity measured. Its Conclusion (p. 18) also links NR3C1 methylation to morning cortisol activity in MDD. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Increased NGFI-A binding site methylation is linked to the severity of experienced emotional abuse, but not physical abuse and/or emotional/physical neglect during childhood, exclusively in depressed individuals and not in healthy probands.

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.
