Representative Western blot analysis of expression levels of several marker proteins of PI3K-pathway in MO59K and MO59J tumor 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
