Combination of mirin and NU7441 with ionizing radiation (IR) treatment significantly enhanced double-strand breaks (DSBs) in esophageal squamous cell cancer (ESCC) cells. (A, B) DSBs were indicated by immunostaining with γ-H2AX. Combinations of mirin (50 µM) or/and NU7441 (5 µM) with IR (6 Gy) treatment significantly improved the number of γ-H2AX foci in both YES2 and KYSE30 cells. Scale bar = 30 µm. All the experiments were independently performed in triplicate. The error bars represent the standard deviation and P values were evaluated by Student’s t-test. *P ≤ 0.05, **P ≤ 0.01, ***P ≤ 0.001, n.s. P > 0.05.
