Figure 3.
The distribution of methylation entropies in tissue samples. The x-axis represents different levels of methylation entropies. The y-axis represents the percentage of genomic loci examined. (A) The distribution of Alu methylation entropies. NC, PN, PA and RL represent normal control, primary non-aggressive, primary aggressive and relapsed ependymoma tissues, respectively. PA1* and RL1* were derived from one same individual. (B) The distribution of methylation entropies of all possible segments with six contiguous CpG sites in promoters and CGIs on chromosome 21.
