Figure Lengend Snippet: MutAPP triggers dynamic imbalance of mitochondrial fission and fusion. N 2 A cells were transfected with pCDNA or APPswe plasmid for 48 h. ( A ) EGFP-labeled APPswe was successfully overexpressed in N 2 A cells. Expression patterns and qualification of the fusion proteins, including ( B , D ) OPA1, ( F , I ) MFN1 and ( G , J ) MFN2, as well as the fission proteins, including ( L , N ) DRP1 and ( P , R ) FIS1 were studied with Western blot. Expression patterns and qualification of ( C , E ) OPA1, ( H , K ) MFN2, ( M , O ) DRP1 and ( Q , S ) FIS1 from the parietal cortex samples of 2×Tg-AD mice were also examined with immunohischemistry. Scale bars = 100 μm. ( T ) Representative electron microscope images showing stages of mitochondria in cortical neurons of WT and APP/PS1 animals. Scale bar = 0.5 μm. Yellow stars: the fissive stage of mitochondria. Significance levels were set at ** p < 0.01, *** p < 0.001 for noted differences between pCDNA and APPswe groups and WT and APP/PS1 groups. Tubulin was used as the loading control.
