ChREBPα enhances mitochondrial oxidative metabolism. A: INS1 cells were treated as indicated and cultured in 11 mmol/L glucose. Mitochondrial membrane potential was determined by TMRE labeling and confocal microscopy. Scale bars = 14 μm. B: The intensity of individual cells in images acquired by confocal microscopy (as shown in A) were quantified with ImageJ software. arb., arbitrary; MFI, mean fluorescence intensity. C: The OCR of INS1 cells cultured in 11 mmol/L glucose was measured using a Seahorse XFe96 analyzer. Oligo, oligomycin; R/A, rotenone and antimycin A. D–G: Graphs show basal respiration (D); maximal respiratory capacity (E) (calculated as the difference between FCCP-induced OCR and OCR after addition of the R/A mixture; OCR by nonmitochondrial organelles); the difference between basal OCR and the oligomycin-insensitive OCR (F), which is the OCR coupled to ATP synthesis; and the spare respiratory capacity (G), calculated by subtracting basal OCR from FCCP-induced OCR. The data shown are the mean ± SE (n = 3 or 4). *P < 0.05, ***P <
