主　　题：remdesivir mitochondrial toxicity cardiotoxicity human primary cardiomyocytes high-throughput screening 

摘      要：Mitochondrial toxicity induced by therapeutic drugs is a major contributor for cardiotoxicity,posing a serious threat to pharmaceutical industries and patients’***,mitochondrial toxicity testing is not incorporated into routine cardiac safety screening *** accurately model native human cardiomyocytes,we comprehensively evaluated mitochondrial responses of adult human primary cardiomyocytes(h PCMs)to a nucleoside analog,remdesivir(RDV).Comparison of their response to human pluripotent stem cell-derived cardiomyocytes revealed that the latter utilized a mitophagy-based mitochondrial recovery response that was absent in h ***,action potential duration was elongated in h PCMs,reflecting clinical incidences of RDV-induced QT *** a screen for mitochondrial protectants,we identified mitochondrial ROS as a primary mediator of RDV-induced *** study demonstrates the utility of h PCMs in the detection of clinically relevant cardiac toxicities,and offers a framework for h PCM-based high-throughput screening of cardioprotective agents.
