Levels of mitochondrial membrane potential. A: Typical fluorescence images of TMRE in control cells (i) and in an shAQP8 cell (ii). The control cells in the image shown were labeled by PKH67. B: Summarized results for the TMRE fluorescence. The fluorescence intensities in shAQP8 cells were normalized against the controls. Data were expressed as the mean±S.D. of total twelve independent experiments (**p<0.01), in which the control cells were labeled in the six experiments and the shAQP8 cells were labeled in another six. Scale bar, 10 µm.
