HIF1α-Induced Glycolysis in Macrophage Is Essential for the Protective Effect of Ouabain during Endotoxemia

Figure 3

Effects of ouabain on glycolysis of macrophages. PMs from WT mice were stimulated with LPS (100 ng/ml) for 1–3 h, and the indicated mRNA expression was determined with qPCR. (a) The supernatant was collected, and the concentration of lactic acid was determined with spectrophotometry. (b) GLUT1 and HK2 mRNA expressions were determined with qPCR. (c) A representative graph output from XF96 showing ECAR response to glucose (10 mM), oligomycin (10 mM), and 2-DG (100 mM). . BMDMs were primed by 25 ng/ml GM-CSF for 24 h. BMDMs were seeded in a 96-well plate for 2 h, and glycolytic activities were examined using the XF Analyzer. (A) Nonglycolytic acidification. (B) Glycolysis. (C) Glycolytic reserve. (D) Glycolytic capacity. ; , , and , Student’s -test.
