PRKN and diabetic cardiomyopathy: Mitophagy can be regulated by several pathways during mitochondrial quality control.13, 20, 21 Amongst these, the PINK1/PARKIN pathway is well‐studied and is involved in the labelling of damaged mitochondria for mitophagy degradation.22 Thus, a better understanding of whether PINK1/PARKIN‐ mediated mitophagy participates in the pathogenesis of diabetic cardiomyopathy is still needed as well as whether they can be targeted therapeutically.
