Fig. 3From: Mechanisms of different response to ionizing irradiation in isogenic head and neck cancer cell linesFold-induction of apoptosis after 5 Gy irradiation in isogenic FaDu, FaDu-RR, and 2A3 cells. Significantly higher fold-induction of apoptosis was observed in FaDu 72 h after irradiation, in comparison to FaDu-RR or 2A3 cells. Bars are AM ± SEM from three independent experiments. ** indicates a significant difference between 5 Gy irradiated and control non-irradiated cells; * indicates a significant difference compared to FaDu-RR and 2A3 cells; n.s. – non-significantBack to article page
