    (A) The ratio of SRD5A2 promoter methylation on individual CpG sites in the promoter region in CRPC and benign prostatic tissues in the Local CRPC cohort. (B) The ratio of SRD5A2 DNA promoter methylation on individual CpG sites in CRPC and benign prostatic tissues in the Met CRPC cohort. (C) Unsupervised cluster analysis of the ratio of SRD5A2 promoter methylation on all CpG methylation sites in the Local CRPC cohort. The CpG methylation sites were clustered into 3 modules, CpG# -72 to -42; CpG# -40 to -35 and -31 to -19; CpG# -34 to -32 and -18 to 65. (D) Unsupervised cluster analysis of the ratio of SRD5A2 promoter methylation on all the CpG methylation sites in the Met CRPC cohort. The methylation sites were clustered into 2 modules, CpG# -72 to -35, -31; CpG# -34 to -32 and -30 to 65. (E) The average methylation level of all tested CpG methylation sites in CRPC and benign prostatic tissues in the Local CRPC cohort. (F) The average methylation level of all tested CpG methylation sites in CRPC and benign prostatic tissues in the Met CRPC cohort. (G) The average methylation level of module 1: CpG# -72 to -40 in CRPC and benign prostatic tissues in the Local CRPC cohort. (H) The average methylation level of module 1: CpG# -72 to -40 in CRPC and benign prostatic tissues in the Met CRPC cohort. (I) The average methylation level of module 2: CpG# -39 to 65 in CRPC and benign prostatic tissues in the Local CRPC cohort.
