MSC-Exo intervention in MI mice can inhibit DMT1 expression and reduce myocardial injury, which is eliminated in exosomes of miR-23a-3p knockout, indicating that MSC-Exo may inhibit DMT1 expression of miR-23a-3p, thereby inhibiting ferroptosis and reducing myocardial injury (76). Here, SLC11A2 is linked to myocardial infarction.
