Abstract

Environment induced epigenetic effects on gene expression in early life are likely to play important roles in mediating the risk of several immune-related diseases. In order to investigate this fully, it is essential to first document temporal changes in epigenetic profile in disease-free individuals as a prelude to defining environmentally mediated changes. Mononuclear cells (MC) were collected longitudinally from a small number of females at birth, 1 year, 2.5 years and 5 years of age and examined for changes in genome-scale DNA methylation profiles using the Illumina Infinium HumanMethylation27 BeadChip array platform. MC from two males were included for comparative purposes. Flow cytomet..
