Isoliquiritin targeting m5C RNA methylation improves mitophagy in doxorubicin-induced myocardial cardiotoxicity

Abstract

Doxorubicin (DOX)-induced myocardial cardiotoxicity (DIC) severely limits its clinical application, and there is no optimal therapeutic agent available. Recent studies revealed that activation of BNIP3-mediated mitophagy and the inhibition of m5C RNA methylation played a crucial role in DIC. Isoliquiritin (ISL) has remarkable cardiac protective effect. But its potential mechanisms against DIC still remains unknown.
