Figure 6

Cluster phenomenon analysis in the promoter region of genes from the immune group. Each bar shows the frequency of genes where all of the probes were negative (only windows with more than three probes were included in the analysis). The position of the probes in the compared groups was matched using a sliding window of 800 bases (with a shift of 50 bases). The upper chart shows the frequency of genes where all of the probes were negative. The lower chart shows the frequency of genes where all of the probes were positive. Note that the frequency of genes where all of the probes were negative (decrease in methylation) was highest in the regions located between −600 and −1,550, while the frequency of genes where all of the probes were positive was highest in the regions located between −750 and −550.
