Fig. 3. (A, B). Radiation response of SK-N-SH neuroblastoma cells in the absence and in the presence of inhibitors of the cell survival pathway BMS345541 (IKK-NF-kB), Stat3-inhibitor-6 and LY294002 (PI3K-AKT). Cell cycle-apoptosis analysis was performed using PI staining of DNA and FACS analysis. DNA content
