Hypomethylation and hypermethylation of six cytokine gene families.

<p>This figure illustrates the percentage of hypomethylated genes and hypermethylated genes in six cytokine gene families. The x-axis denotes the gene family, and the y-axis denotes the percentages of hypomethylated and hypermethylated genes in each of these gene families. The light and dark grey areas represent the hypomethylated and hypermethylated genes, respectively.
