Fig. 7: Loss of differentiation markers in HG CRC cell lines is associated with promoter methylation.

A Heatmap of corresponding methylation changes in promoters of 519 of the 1763 genes differentially expressed between HG and LG CRC cell lines. B, C Correlation of differential promoter methylation and differential gene expression for genes with B lower expression in HG cell lines (n = 346) and C lower expression in LG cell lines (n = 173).
