1 Synergic effects of beta-estradiol and erythromycin on hERG currents. Erythromycin ETS transcription factor ERG Homo sapiens
2 With simultaneous application of 10 muM erythromycin, which is known to block hERG currents but not in low doses, the blocking effects of beta-estradiol on hERG currents were enhanced. Erythromycin ETS transcription factor ERG Homo sapiens
3 With simultaneous application of 10 muM erythromycin, which is known to block hERG currents but not in low doses, the blocking effects of beta-estradiol on hERG currents were enhanced. Erythromycin ETS transcription factor ERG Homo sapiens
4 Namely, hERG currents were inhibited maximally to 45.8% of control with an IC50 of 59 nM (P<0.02) by beta-estradiol with 10 muM erythromycin. Erythromycin ETS transcription factor ERG Homo sapiens
5 We conclude here that a significant block of hERG currents by beta-estradiol may account for the sex-related differences in LQTS and the synergic effects of beta-estradiol and erythromycin indicate a higher risk of drug-induced TDP in women than men. Erythromycin ETS transcription factor ERG Homo sapiens
