Abstract
The effects of ionizing radiation on DNA methylation are of importance due to the role that DNA methylation plays in maintaining genome stability, and the presence of aberrant DNA methylation in many cancers. There is limited evidence that radiation-sensitivity may influence the modulation of DNA methylation by ionizing radiation, resulting in a loss of methylation. The BALB/c, CBA and C57Bl/6 strains are the most commonly utilized mouse strains in radiation research and are classified as radiation sensitive (BALB/c and CBA) or radiation resistant (C57Bl/6). We present here the first direct comparison of changes in repeat element DNA methylation (L1, B1 and Intracisternal A Particle; IAP) ov..
