Tumors smother their epigenome

DNA hypermethylation is pervasive in tumors, but the factors triggering this modification are largely unknown. We recently demonstrated that the activity of 10-11-translocation methylcytosine dioxygenases, initiators of DNA demethylation, is compromised in hypoxic tumors. The resultant accumulation of methylation inactivates associated genes, linking the tumor microenvironment to epigenetic changes in cancer cells.
