Percent DNA methylation in mononuclear and polymorphonuclear cells.

<p>Percent DNA methylation (y-axis) in mononuclear and polymorphonuclear cells (MNCs and PMNCs) per CpG site (x-axis) in four CGIs located in the <i>HHEX</i>, <i>KCNJ11</i>, <i>KCNQ1</i> and <i>PM20D1</i> genes respectively (n = 20 each). Data for each CGI are depicted in a separate boxplot where measurements for MNCs are shown in red and for PMNCs in blue. The dotted lines separating the boxes indicate that at each CpG site a pair of data are being compared (i.e., for MNCs and PMNCs). Significantly (p<0.01) differentially methylated CpG sites (MNCs versus PMNCs DNA methylation) are indicated with an asterisk.
