The cell survival during fractionated irradiation under 4-MU administration. Dose–response curve of HT1080 cells for each 4-MU concentration irradiated by (A) 2 Gy/fraction scheme or (B) 10 Gy/fraction scheme. Charcoal line is the dose–response curve of the non-treated cells, red line is the curve of the 80 μM 4-MU treated cells, and blue line is the curve of the 100 μM 4-MU treated cells. The horizontal black dotted line represents the surviving fraction Sc = 10–5.
