Age-related differences in monocyte DNA methylation in Kenyan adults and children. Monocytes were negatively selected from fresh venous blood samples from healthy Kenyan children (n = 8) and adults (n = 8). a Principal components analysis (PCA) plot of DNA methylation results for Kenyan adult (red) and child (blue) monocytes. b Heatmap of DNA methylation results showing differentially methylated positions between Kenyan adult and child monocytes, includes all CpG probe sites meeting differential methylation criteria (absolute beta value difference > 0.15, p < 0.01, and FDR-adjusted p < 0.05). c Plot of differentially methylated region in the CLEC12A gene locus, showing beta values for Kenyan adult (red) and child (blue) monocytes at 6 CpG probe sites within the region. d KEGG pathway enrichment analysis of genes associated with differentially methylated positions in monocytes from Kenyan adults vs. children, showing the most significantly enriched pathways
