Methylation levels assessed by RT-MSP for CGIs located on <i>CCDC17</i>, <i>PVR</i>, and <i>MAP3K11</i> gene bodies in SCC, KA, and normal epidermis.

<p>(a) The methylation level of each sample in SCC cell lines, clinical SCC samples, clinical KA samples, clinical normal epidermis samples, and controls including methylated DNA (M) and unmethylated DNA (U) is indicated as a bar graph. The vertical and horizontal axes indicate the methylation level (%) and sample ID, respectively. (b) Averages and standard deviations of methylation levels in each sample group are indicated as bar graphs. The vertical and horizontal axes indicate the average methylation level (%) with standard deviation and sample ID, respectively. An asterisk represents a significant difference (<i>P</i> < 0.05).
