Dotplot showing differential methylation. The β-values for four genes (DAB2I, ITGA4, PRKAR1B and IL21R) in both normal (blue) and CRC (red) tissue samples. Connecting lines indicate paired samples (indicating same patient). DAB2I, ITGA4 and PRKAR1B show hypermethylation in the CRC samples when compared to the normal tissue and IL21R shows hypomethylation in the CRC samples when compared to the normal tissue.
