Colon Cancer Epigenome (IMAGE) IDIBELL-Bellvitge Biomedical Research Institute Caption This is an example of three complete colon cancer epigenomes of a patient. The innermost concentric circle represents the normal colon tissue, the intermediate the primary colon tumor and the outermost themetastasis derived from that colon tumor. As the tumor progresses the representation changes from dark blue to light blue, indicating the loss of the correct epigenetic signals. In the periphery, the 23 human chromosomes are represented with different colors.
