Heterogeneity of p14ARFpromoter methylation in colorectal tumors. The samples analyzed are represented on the horizontal line, and the 27 CpG sites on the vertical line. For each case, the methylation status of each individual CpG site is shown: an empty block indicates that the concerned CpG site is unmethylated, a black block indicates that the concerned CpG sites is fully methylated, and a gray block indicates that the concerned CpG site is partially methylated.
