Heat map of gene expression data of the selected marker set in 5-aza-2’-deoxycytidine-treated human colon adenocarcinoma cells (GSE29060; GSE14526; GSE32323). Intensity values on the colour scale were as follows: red – high intensity, black – intermediate intensity, green – low intensity. Demethylation treatment resulted in varying degrees of upregulation of certain transcripts
