a, b HCT116:p53+/+, HCT116:p53−/− cells, HCT116:ACER2+/+, or HCT116:ACER2+/+ cells were treated with IR-low, IR-high, or sham, and 24 h later, the cells were subjected to LC/MS/MS analyzes for SPH, S1P, or ceramides. The data represent mean values ± SD of three independent experiments. Statistical analyzes were performed as described in Methods section. *represents p < 0.001 and # p < 0.01
