Overview of potential miRNA involvement in DIC. DOX treatment increases apoptosis and ferroptosis in cardiomyocytes. Rather than oxidative stress, DOX inhibition of Top2B and subsequent DNA damage response may be the primary contributor to cardiomyocyte death. miRNAs may aid in the regulation of molecular pathways that connect DNA damage response and apoptosis/ferroptosis.
