Figure 4From: BRAF mutation-specific promoter methylation of FOX genes in colorectal cancerRelation between methylation and expression. Tumor/normal expression ratios (y axis) were plotted against the average DNA methylation measured by bisulfite sequence analysis for FOXB2 (A) and FOXF1 (B), and the methylation log2 ratio measured by CpG array for FOXD3 (C). BRAF mutant samples are shown in red, wildtype samples in black.Back to article page
