Figure 1

PCA plot and heatmap based on the 182 differentially methylated CpG loci (p ≤ 0.001) from the regression model considering IgG titers. (A) PCA scatter plot demonstrates separation according to the anti-peptide IgG levels. (B) Heatmap representing the similarities of DNA methylomes clustered according to their IgG levels (in fold change). The columns represent the CpG probes and rows the samples taken from indicated subjects. CpG probes with no changes in methylation have a value of zero and colored in black. Hypermethylated probes are displayed in red and hypomethylated probes in green. Subjects' study-numbers and fold increases in anti-peptide antibody titers are shown.
