Fig 2. Effects of irradiation on cell survival and PARPi-FL uptake.

Fig 2

(A) Examples of clonogenic growth of FaDu and Cal27 cells without (0 Gy) and after 10 Gy irradiation. (B) Clonogenic survival curve of FaDu and Cal27 cells after 0, 2, 4, 6, 8 and 10 Gy irradiation. Means ± SEM of three independent experiments with three parallels each. The asterisk indicates a p-value < 0.05 between FaDu and Cal27 cells using Student’s t-test. (C) Nuclear PARPi-FL uptake without and after 10 Gy irradiation, as observed microscopically in FaDu cells and (D) Cal27 cells. Nuclear localization was confirmed by Hoechst DNA stain. Representative images from n = 3 experiments.
