Abstract

Despite that burnout presents a serious burden for modern society, there are no diagnostic criteria. Additional difficulty is the differential diagnosis with depression. Consequently, there is a need to dispose of a burnout biomarker. Epigenetic studies suggest that DNA methylation is a possible mediator linking individual response to stress and psychopathology and could be considered as a potential biomarker of stress-related mental disorders. Thus, the aim of this review is to provide an overview of DNA methylation mechanisms in stress, burnout and depression. In addition to state-of-the-art overview, the goal of this review is to provide a scientific base for burnout biomarker research. We performed a systematic literature search and identified 25 pertinent articles. Among these, 15 focused on depression, 7 on chronic stress and only 3 on work stress/burnout. Three epigenome-wide studies were identified and the majority of studies used the candidate-gene approach, assessing 12 different genes. The glucocorticoid receptor gene (NR3C1) displayed different methylation patterns in chronic stress and depression. The serotonin transporter gene (SLC6A4) methylation was similarly affected in stress, depression and burnout. Work-related stress and depressive symptoms were associated with different methylation patterns of the brain derived neurotrophic factor gene (BDNF) in the same human sample. The tyrosine hydroxylase (TH) methylation was correlated with work stress in a single study. Additional, thoroughly designed longitudinal studies are necessary for revealing the cause-effect relationship of work stress, epigenetics and burnout, including its overlap with depression.

  • The majority of findings relating to the epigenetics of psychosocial stressors and monoaminergic neurotransmission point towards hypermethylation of SLC6A4 and hypomethylation of MAOA, mirroring results in categorical analyses of MDD patients.

    “Notably, the majority of findings relating to the epigenetics of psychosocial stressors and monoaminergic neurotransmission point towards a hypermethylation of SLC6A4 and a hypomethylation of MAOA, mirroring the results observed in categorical analyses of MDD patients (Bakusic, Schaufeli, Claes, & Godderis, 2017;Schiele et al., 2019), further stressing the need for longitudinal study designs”
  • Methylation of NR3C1 may result in heightened gene expression, reduced PTG after trauma and dysfunctional HPA-axis function.

    “Therefore, methylation of NR3C1 may result in heightened gene expression, reduced PTG after trauma and dysfunctional HPA-axis function.”
  • Methylation and expression of NR3C1 promotor associated regions has been consistently implicated in the pathophysiology of PTSD and other related disorders such as depression.

    “This replicates previous findings where methylation and expression of NR3C1 promotor associated regions has been consistently implicated in the pathophysiology of PTSD and other related disorders such as depression (see Bakusic et al., 2017;Watkeys et al., 2018 reviews)”
  • These two different methylation patterns tend to increase gene expression, and have previously been associated with heightened distress and PTSD symptoms.

    “These two different methylation patterns tend to increase gene expression (Bakusic et al., 2017;Dudley et al., 2011), and have previously been associated with heightened distress and PTSD symptoms (see Watkeys et al., 2018 review).”

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.
