Differential DNA methylation regions in cytokine and transcription factor genomic loci associate with childhood physical aggression
Ontology highlight
ABSTRACT: Animal and human studies suggest that inflammation is associated with behavioral disorders including aggression. We have recently shown that physical aggression of boys during childhood is strongly associated with reduced plasma levels of cytokines IL-1a, IL-4, IL-6, IL-8 and IL-10, later in early adulthood (Provencal et al., unpublished data). This study tests the hypothesis that there is an association between differential DNA methylation regions in cytokine genes in T cells and monocytes DNA in adult subjects and a trajectory of physical aggression from childhood to adolescence. We compared the methylation profiles of the entire genomic loci encompassing the IL-1a, IL-6, IL-4, IL10 and IL8 and three of their regulatory transcription factors (TF) NFkB1, NFAT5 and STAT6 genes in adult males on a chronic physical aggression trajectory (CPA) and males with the same background who followed a normal physical aggression trajectory (control group). We used the method of methylated DNA immunoprecipitation (MeDIP) with comprehensive cytokine gene loci and TF loci microarray hybridization, statistical analysis and false discovery rate correction.
