FUNDC1 and myocardial infarction: Together, our results suggest that, although starvation and Fundc1 TG induce comparably higher general autophagy than wild type in the hearts after acute MI, mitophagy was not significantly changed in starvation‐treated mouse hearts compared with wild‐type mice, that is only Fundc1 TG increases specific mitophagy, no matter under basal condition or after acute MI.
