TY - JOUR PY - 2017// TI - Epigenetic profiles associated with major depression in the human brain JO - Psychiatry research A1 - Bustamante, Angela C. A1 - Armstrong, Don L. A1 - Uddin, Monica SP - 439 EP - 442 VL - 260 IS - N2 - We conducted an epigenome-wide association study of Major Depressive Disorder (MDD) in brain-derived DNA using two analytic approaches. DNA methylation data (GSE41826) was used in differential methylation (DM) analyses controlling for age, sex, suicide status, and post-mortem interval; and in weighted gene co-methylation network analyses (WGCNA) in probes mapping to transcription start sites. No probes in the DM analysis survived FDR correction. Nominally significant DM probes were enriched in synaptic function-related genes. WGCNA revealed one module correlated with MDD, enriched in genes associated with mitochondrial function. DM and WGCNA both showed enrichment of genes involved in transcription and DNA binding.
