In this study, we examined the induction of a radio-adaptive response to cell death using a colony formation test in m5S, G401.2/6TG.1 and HeLa cells. When m5S cells were subjected to priming irradiation of 0.05 to approximately 0.15 Gy 4 hr before being irradiated with 4.5 Gy, the survival ratios increased significantly to 39 to approximately 42%. The priming irradiation effect was also observed when G401.2/6TG.1 cells were subjected to priming irradiation of 0.025 to approximately 0.1 Gy 4 hr… CONTINUE READING
