The expression of XPF and/or APE was suppressed by siRNAs in HeLa cells & the cellular sensitivity to gemcitabine was examined. XPF- or APE-suppressed HeLa cells (closed square & closed triangle, respectively) showed sensitivity to gemcitabine. Cosuppression of XPF & APE (closed circle with dashed line) resulted in the sensitivity to gemcitabine similar to the sensitivity induced by the suppression of XPF or APE individually. A control siRNA (siControl) was used as a control (open diamond). Three independent experiments were performed & averages of surviving fraction are plotted. The error bars show standard deviations. The differences in the gemcitabine sensitivity between the control cells & the cells treated with siXPF, siAPE, or siXPF+siAPE are statistically significant at 10 nM & 50 nM with p<0.05. The western blots showed a significant suppression of XPF (more than 95%) & ~75% reduction in the expression of APE with the siRNA treatment.

The presence of XPF & APE was detected by western blots. The asterisk (∗) shows a cross-reacted protein with the anti-XPF antibody. Histone H2AX was used as a loading control. Gemcitabine-induced recruitment of XPF to chromatin (lanes 1-3) was compromised in HCT116 shAPE cell line (lanes 4-5). The chromatin-bound APE is not changed by the gemcitabine treatment (lanes 4-6, Supplementary Figure 5). A signal of XPF (and APE) was normalized with a signal of H2AX in each chromatin fraction using ImageJ software. Then a ratio of chromatin-bound XPF with gemcitabine to XPF in control was determined & depicted as bar graphs. Three independent experiments were performed & averages of the ratio at indicated time points were plotted. The error bars show standard deviations. Only the difference in the chromatin-bound XPF between chromatin from control experiments & chromatin that was incubated one hour with 1 μM gemcitabine is statistically significant in HCT116 (p<0.05).
