WebJan 30, 2024 · The hERG IC50:C max ratio was correlated with TdP incidence for culprit drugs. This validation provides support for the potential use of the hERG IC50:C max ratio for clinical decision making in instances of drug selection where TdP risk is a concern. Citing Literature.

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. WebMay 1, 2024 · For both Pluricyte® Cardiomyocytes and GP-CMs the response to the hERG channel blockers was less sensitive than expected based on literature (E4031 hERG IC50 = 7 nM (Harris et al., 2013), dofetilide hERG IC50 = 5 nM (Redfern et al., 2003)) and compared to studies described herein using Pluricyte® Cardiomyocytes in MEA and … WebDec 6, 2024 · In addition, relative hERG current level on application of 100 µM 4-HIAA (n = 6, red) or 1 µM E4031 (n = 5, green) is displayed. For testing this hypothesis, hERG channels were heterologously expressed in tsA-201 cells, and inhibition of currents through these channels by psilocin was investigated with the whole-cell patch clamp technique. can index match match multiple values
