(A) Confocal images of FIS1 RNAi, DRP1‐DN and control cells coexpressing the AP marker LC3:GFP (green), and stained with MTR (red, control and FIS1 RNAi group) or mtDsRed (red, DRP1‐DN) and treated with pepstatin A and E64d to arrest digestion in late APs. A magnified area within a FIS1 RNAi cell shows APs with and without mitochondria (white and blue circles respectively). Scale bar, 5 μm.
