Fig. 4From: Combining carbon ion irradiation and non-homologous end-joining repair inhibitor NU7026 efficiently kills cancer cellsEffect of NU7026, B02 and irradiation on DNA damage accumulation in H1299 cells. Fluorescence intensity of γH2AX in 10 μM NU7026 (a), 10 μM B02 (b) and/or radiation-treated cells. The presented results are the mean and SD of three independent experiments. Data were statistically evaluated with student’s t test with comparisons between irradiation alone and other treated groups (* p < 0.05; ** p < 0.01; NS, non-significant)Back to article page
