Figure 4.
Correlation of VCX gene promotor methylation levels and mRNA expression. Spearman correlation between average promotor methylation levels, shown as ß-values and mRNA expression of all VCX family genes in healthy and cancerous breast tissue and melanoma. A significant correlation was observed for all VCX family genes in both breast cancer and melanoma, but not in healthy breast tissue. Blue indicates primary tumor specimens and red indicates metastatic tumor specimens. The p-values were calculated using the (unpaired) Mann-Whitney U test.
