F. Representative images for co-localization between RPA32 (green) and telomeres (red FISH probe) in the indicated cell lines treated with either DMSO or 10 μM NU7026 DNA-PK-inhibitor (DNA-PK-i) for 48 h. White arrows indicate co-localization events. Quantifications are shown on the right. A total of 53-84 nuclei were scored from three independent experiments. Statistical analyses were performed using one-way ANOVA with post-hoc Games-Howell's test for multiple comparisons. Data information: All scale bars: 5 μm. Data are shown as mean ± SD, with the red line marking the mean value. Statistical analyses were performed with Student's two-tailed unpaired t-test with Welch's correction for normality of distribution unless specified otherwise.
