DNM1L and diabetes mellitus: Although mitochondrial dynamics have been shown to be altered in the diabetic retina, reflected by an altered expression of molecular effectors controlling fusion (e.g., Mitofusins) and fission (e.g., Dynamin-related protein 1 [Drp1])18, the manner in which these processes interplay with mitophagy and biogenesis to control MQC during diabetes remains unknown.
