The levels of the antioxidant enzyme manganese superoxide dismutase (Mn-SOD) are frequently decreased in tumor cells and increased in normal cells upon treatment with ionizing radiation. We studied Mn-SOD at different stages during the neoplastic conversion of radiation-initiated Syrian hamster embr
