CCCP-induced parkin-mitochondrial aggregate formation is an intermediate step for mitophagy. (A) MEFs expressing WT GFP-parkin were treated with CCCP or CCCP and nocodazole (NOC, 10 µM) for 8, 16, and 24 h as indicated. Cells were immunostained with anti-Tom20 to visualize mitochondria. GFP-parkin–positive cells are marked by dotted lines. Arrows indicate parkin-positive mitochondria or mitochondrial aggregates. Bar, 25 µm. (B) The average percentages of cells with mitochondrial aggregates or without mitochondria from three independent experiments from A are presented with standard deviation as error bar. **, P < 0.01.
