Figure Lengend Snippet: a The represent image of fluorescence microscope. The polymer statu of JC-1 indicate the higher MMP (red) and the monomer statu of JC-1 indicate the lower MMP (green). b Ratio of red fluorescence to green fluorescence. c ATP levels from neuronal lysates. d Confocal microscopy of cultured neurons using a PDH antibody (green) and Map-2 antibody (red). The boxed area in each subpanel is magnified below its corresponding subpanel and shows neurites. e Mean mitochondrial aspect ratio in the box areas in c . f Quantitative analysis of the green fluorescent intensity in the boxed area (1367.02 μm length of neurites from the control group, 1058.74 μm length of neurites from the Fen group). g In vivo and h in vitro protein levels of PSD-95, synaptotagmin, and synapsin detected by Western blotting (top panel) and quantitative analysis of protein-band intensities are shown (bottom panel). i Averaged mEPSCs from an example recording are shown (left panel), and quantitative analysis of frequency and amplitude are shown (right panel). Figure d and h are represent same samples, therefore, Actin in Fig. d and h are completely identical. For all quantitative/statistical analysis, * p < 0.05; ** p < 0.01; and *** p < 0.001. All data are presented as means ± SEM. Scale bars are 20 μm in c .
