Epigenetic DNA methylation in radiation biology: on the field or on the sidelines?

Abstract

DNA methylation has been studied with regard to chemotherapeutics for a number of years. The radiation field has just begun to look at this in the context of radiotherapy or radiation exposure. So far, the data suggest that radiation induces epigenetic reprogramming which indicates a purposeful response that influences the cell fate or alters the response to future exposure. Further studies may result in discovery of biomarkers for radiotherapy outcome or prediction of the degree of radiation resistance. Past and ongoing development of DNMT1 inhibitors that lead to DNA hypomethylation appear to sensitize many tumor types to radiation and may be an area with long term clinical implications.
