WebApr 24, 2024 · E4031 (3 µM) did not increase the number of residual γH2AX foci (Figures 5E, F) suggesting that hERG signaling is not involved in DNA DSB repair. Combined, the data indicate that hERG1 channels contribute to the stress response and clonogenic survival of irradiated K562 cells but do not promote DNA repair. WebIrradiation (0 and 5 Gy) and post-incubation (8 h) were carried out either in the absence (1 st and 3 rd plot) or presence (2 nd and 4 th plot) of the hERG channel inhibitor E4031 (3 µM).
