WebSep 1, 2007 · Cells were exposed to a HERG-specific channel blocker, E4031. Half-maximal inhibitory concentration (IC50) of the blocker was 4.69 nm. The kinetics of the HERG1 current in K562 cells resembled the rapid component of the native cardiac delayed rectifier current, known to be conducted by heterotetrameric HERG1 channels. 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.
