doi: 10.1249/MSS.0000000000003203
Figure Lengend Snippet: Effects of aerobic exercise on mitochondrial damage and cell permeability after CS. AICAR was used 24 h before stretching to simulate the effect of aerobic exercise in mice. A and G, The expression of VDAC1, p66shc, PINK1, p120, and Occludin was determined by Western blot. B and C, MMP and ROS production were detected by FCM. D, Mitochondrial respiration in each group of HMLVEC was analyzed by O2K. E, Electron microscopy images of HLMVEC cells (scale bars, 1 μm). F, Mitochondrial imaging of living HLMVEC cells. H, The colocalization of p120 ( green ) and VE-cadherin ( red ) in HLMVEC cells was determined by immunofluorescence. Nuclei were stained with DAPI ( blue ). Scale bar, 10 μm. I, Immunofluorescence was used to detect the distribution of F-actin ( green ) and p120 ( red ). Nuclei were stained with DAPI ( blue ). Scale bar, 10 μm. * P < 0.05 vs control; # P < 0.05 vs CS 4-h group. Experiments were repeated at least three times.
