Representative Western blot analysis demonstrating the expression of several DNA repair proteins of the NHEJ pathway in MO59K and MO59J cells treated with DMSO (control) or PI-103 for 3 h prior to IR with 8 Gy and detected 30 min and 24 h thereafter. β-actin was used as loading control. The uncropped blots are shown in Fig. S12. The experiment was repeated at least three times
