description:
Chronic physical aggression (CPA) is characterized by frequent use of physical aggression from early childhood to adolescence. Observed in approximately 5% of males, it is associated with early childhood adverse environments. DNA methylation, a covalent modification of DNA, regulates genome function and has been associated with early childhood adverse environments. We analyzed T cell DNA genome-wide promoter methylation profiles from two groups of adult males assessed annually for frequency of physical aggression between 6 and 15 years of age: a group with CPA and a control group. Whole genome methylation analysis was performed using MeDIP followed by hybridization to microarrays. We mapped the promoter regions of 20 000 genes and 400 microRNAs. Overall design: The subjects were recruited from participants in two longitudinal studies of child development9,47. We recruited two groups of Caucasian males who were born in families with a low socioeconomic status and were living at the time of the present study within 200km from our laboratory. The first group had a history of high physical aggression from age 6 to 15 years (chronic physical aggression group, CPA). The second group was recruited from the same longitudinal studies but included only those who did not have a history of high physical aggression from age 6 to 15 (Control group). A total of 65 eligible subjects agreed to participate (8 CPA and 57 controls). Using custom-designed microarrays with 244K probes tiling the promoter regions of 20000 genes and 400 microRNAs, we obtained DNA methylation profiles by meDIP-chip. Each profile was generated in triplicate.
