LCLs harboring mtDNA mutations display growth and respiration defects. a The ratios of cell growth in galactose media compared to glucose media are graphed. A ratio of 1.0 means that the cell line grows at the same rate in glucose or galactose media, whereas a ratio < 1.0 means that the cell line grows slower in galactose media compared to glucose media. GM00333 (wildtype) cells grow at a similar rate in either glucose or galactose media, but all LCLs with mtDNA mutations exhibit slower growth in galactose media. b, c Cells were seeded at equal confluency and oxygen consumption rates (OCR) were measured and plotted. Basal OCR is measured without the addition of mitochondrial inhibitors (b); maximal OCR is measured after the addition of oligomycin and FCCP (c). LCLs with mutations in complex I subunits display decreased basal respiration rates. All LCLs with mtDNA mutants display decreased maximal respiration rates. Average ± SEM from three independent experiments are shown. *p < 0.05, **p < 0.01, ***p < 0.001, ****p < 0.0001, by Dunnett’s multiple comparisons test after one-way ANOVA, vs. GM00333 (wildtype) cells
