Article Title: Multiple Dynamin family members collaborate to drive mitochondrial division
Figure Lengend Snippet: Inhibition of clathrin-mediated endocytosis does not affect mitochondrial morphology a , Representative images of TOM20 immunofluorescence in n = 50, 50, 52 COS-7 cells transfected with scrambled control, AP-2, or Dyn2 siRNA. Scale bars = 10 μm. b , Immuno-blots with antibodies against AP-2, Dyn-2, and GAPDH in siRNA-treated cells. c , The effect on mitochondrial morphology was quantitated within a 230 μm 2 region of interest (ROI) for mean area per mitochondria (left graph), and mean mitochondria per ROI (right graph). As in , Dyn2–depleted cells had larger mitochondria and less mitochondrion per ROI compared to control cells; however, AP-2 depleted cells displayed mitochondrial morphology that was qualitatively and quantitatively similar to control cells. These data were obtained from three biological replicate experiments. Error bars represent the s.e.m. *p
