Figure 4. Glycolysis is significantly enhanced in SOX2-high MCF7 cells. MCF7 cells stably-transduced with the SOX2-GFP construct were subjected to FACS sorting to isolate the 5% highest GFP (GFP-high) and the 5% lowest GFP (GFP-low) subpopulations. The Seahorse XF96 analyser was employed to measure glycolytic function. In the top panel, a representative ECAR tracing is shown. In the lower panel, bar graphs show the glycolytic rate, glycolytic capacity and glycolytic reserve, obtained from the ECAR quantification. Experiments were performed at least 3 times independently. Results are shown as the mean ± SD: t-test, two tailed-test, *p < 0.05, ** p < 0.01.
