Fig. 6. Decreased apoptosis after NADH treatment. (a) Flow cytometry analysis of apoptosis in AIF-WT and AIF variant stable transfection cell lines with NADH administration (200 µmol/L for 24 h). (b) Quantification analysis of apoptosis in AIF-WT and AIF variant stable transfection cell lines. Data are represented as mean±SEM (n=3). ^** P<0.01. The dotted line represents the average value of two clones. AIF: apoptosis-inducing factor; WT: wild type; NADH: nicotinamide adenine dinucleotide; SEM: standard error of the mean; PE: phycoerythrin; FITC: fluorescein isothiocyanate; UL: upper left; UR: upper right; LL: lower left; LR: lower right.
