Effect of ICp6-Cu and X-ray irradiation on cell cycle distribution in NT8e and 4451 at 24 h post-irradiation. (a) Cell cycle histograms of NT8e (i) and 4451 (ii) cells. (b) Percentage of NT8e (i) and 4451 (ii) cells in sub-G1-phase, for control, ICp6-Cu treatment alone, X-ray irradiation alone and ICp6-Cu plus X-ray treatment. The cells were treated with 30 µM ICp6-Cu for 3 h and then irradiated with X-rays at a fixed dose of 7 Gy. Data represent mean ± standard deviation obtained from three independent experiments. *(p < 0.05), **(p < 0.01) indicate statistical significance. |
