BACKGROUND: DNA methylation in the promoter region of the glucocorticoid receptor gene (NR3C1) is closely associated with childhood adversity and suicide. However, few studies have examined NR3C1 methylation in relation to major depressive disorder (MDD) and hippocampal subfield volumes. We investigated the possible association between NR3C1 methylation and structural brain alterations in MDD in comparison with healthy controls. METHODS: We compared the degree of NR3C1 promoter methylation in the peripheral blood of non-psychotic outpatients with MDD and that of healthy controls.

BACKGROUND: Enhanced glucocorticoid receptor (GR) sensitivity is present in people with posttraumatic stress disorder (PTSD), but the molecular mechanisms of GR sensitivity are not understood. Epigenetic factors have emerged as one potential mechanism that account for how trauma exposure leads to sustained PTSD symptoms given that PTSD develops in only a subset of trauma survivors.

Variation in the serotonin transporter gene (5-HTT; SERT; SLC6A4) has been suggested to pharmacogenetically drive interindividual differences in antidepressant treatment response. In the present analysis, a 'pharmaco-epigenetic' approach was applied by investigating the influence of DNA methylation patterns in the 5-HTT transcriptional control region on antidepressant treatment response.

BACKGROUND: Although genetic variation is believed to contribute to an individual's susceptibility to major depressive disorder, genome-wide association studies have not yet identified associations that could explain the full etiology of the disease. Epigenetics is increasingly believed to play a major role in the development of common clinical phenotypes, including major depressive disorder. RESULTS: Genome-wide MeDIP-Sequencing was carried out on a total of 50 monozygotic twin pairs from the UK and Australia that are discordant for depression.

BACKGROUND: Alterations of brain-derived neurotrophic factor (BDNF) DNA methylation at specific BDNF promoters and corresponding gene expressions are associated with pathology and the response to antidepressant (AD) therapy in affective disorders such as major depressive disorder (MDD) and bipolar disorder (BD). METHODS: Genomic DNA was derived from peripheral blood mononuclear cells (PBMCs) and was bisulfite converted. Percentage of methylated reference (PMR) was calculated based on results from quantitative real-time PCR following the MethyLight protocol.

BACKGROUND: Major depressive disorder (MDD) exhibits numerous clinical and molecular features that are consistent with putative epigenetic misregulation. Despite growing interest in epigenetic studies of psychiatric diseases, the methodologies guiding such studies have not been well defined. METHODS: We performed DNA modification analysis in white blood cells from monozygotic twins discordant for MDD, in brain prefrontal cortex, and germline (sperm) samples from affected individuals and control subjects (total N = 304) using 8.1K CpG island microarrays and fine mapping.

Early life stress (ELS) is associated with increased vulnerability for diseases in later life, including psychiatric disorders. Animal models and human studies suggest that this effect is mediated by epigenetic mechanisms. In humans, epigenetic studies to investigate the influence of ELS on psychiatric phenotypes are limited by the inaccessibility of living brain tissue.

OBJECTIVE: The authors compared the effectiveness of fluoxetine and desipramine treatment in a prospective double-blind pharmacogenetics study in first-generation Mexican Americans and examined the role of whole-exome functional gene variations in the patients' antidepressant response. METHOD: A total of 232 Mexican Americans who met DSM-IV criteria for major depressive disorder were randomly assigned to receive 8 weeks of double-blind treatment with desipramine (50-200 mg/day) or fluoxetine (10-40 mg/day) after a 1-week placebo lead-in period.

Major depressive disorder (MDD) is a leading cause of disability worldwide and is associated with poor psychological, medical, and socioeconomic outcomes. Although much has been learned about the etiology and treatment options of MDD over the past decade, there remain unanswered questions that pose challenges to improving acute and chronic outcomes for those with MDD. MDD is a clinically heterogeneous disorder.

Considerable evidence suggests a crucial role for the epigenetic regulation of brain-derived neurotrophic factor (BDNF) in the pathophysiology of major depressive disorder (MDD). However, the relationship between BDNF DNA methylation and white matter (WM) integrity in MDD has not yet been investigated. In the current study, we examined the association between the DNA methylation status of the BDNF promoter region and WM integrity in MDD.
