A A process for identification of candidate DNA methylation-based markers of CRC. B Unsupervised hierarchical clustering of ten methylation-based markers selected for the diagnosis of CRC in the 45 TCGA paired CRC samples. C Unsupervised hierarchical clustering of ten methylation-based markers in 840 blood leukocytes of healthy individuals. D Unsupervised hierarchical clustering of ten methylation-based markers in 4525 tumor and normal tissues of ten other cancer typesBack to article page
