Radiation sensitivity for MCF-7-Snail and MCF-7-Control cells. I Radiation sensitivity determined from the number of viable cells 72 h post-irradiation by specified doses of X-ray. Viable cells [%] corresponds to the number of viable cells determined by Tox-8 assay in treatment relative to non-irradiated control cultures (N = 2 replicates; *: p <0.05; **: p <0.01); error bars = SD. II Micrographs of MCF-7-Snail (a, b) and MCF-7-Control cells (c, d) 72 h post-irradiation with 0 Gy (a, c) or 4 Gy (b, d). Scale bar: 100 μm. SN = MCF-7-Snail cells; CT = MCF-7-Control cells
