X-ray photon irradiation dose-dependently impairs GB mitochondrial function. a Micrographs of colony forming units (CFU; > 50 cells) 10-day post-RT with/out 1 mM NAC pre-treatment. Column graph shows mean CFU ± standard error of the mean (SEM) of triplicates from three independent experiments. b Histogram of ROS negative (blue) and positive (red) cells at 72 h post-irradiation. Grey overlay shows the profile at 0 Gy. Column graphs show mean percentage of ROS + cells (%) ± SEM of duplicates from three independent experiments. (a and b) *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001 vs 0 Gy determined by two-way ANOVA with Dunnett’s multiple comparison test
