1 Thioridazine Induces Cardiotoxicity via Reactive Oxygen Species-Mediated hERG Channel Deficiency and L-Type Calcium Channel Activation. Thioridazine ETS transcription factor ERG Homo sapiens
2 The present study was aimed at exploring the long-term effects of THIO on the hERG and L-type calcium channels, both of which are relevant to the development of QT prolongation. Thioridazine ETS transcription factor ERG Homo sapiens
3 The ROS scavenger N-acetyl cysteine (NAC) significantly attenuated hERG reduction induced by THIO and abolished the upregulation of ER stress marker proteins. Thioridazine ETS transcription factor ERG Homo sapiens
4 Meanwhile, THIO increased the degradation of hERG channels via disrupting hERG-Hsp70 interactions. Thioridazine ETS transcription factor ERG Homo sapiens
5 Meanwhile, THIO increased the degradation of hERG channels via disrupting hERG-Hsp70 interactions. Thioridazine ETS transcription factor ERG Homo sapiens
6 In conclusion, dysfunction of hERG channel proteins and activation of L-type calcium channels via ROS production might be the ionic mechanisms for QT prolongation induced by THIO. Thioridazine ETS transcription factor ERG Homo sapiens
