Fig. 5From: An adiponectin-S1P axis protects against lipid induced insulin resistance and cardiomyocyte cell death via reduction of oxidative stressManipulation of S1P action significantly alters cell death in H9c2 cells. Cell death in H9c2 cells measured using a a) LDH, b) MTT or c) Trypan blue assay. Following a preincubation with 0.5% FBS, cells were incubated with 0.1 mM FA for 24 h and were also treated with the addition of 35 μM AdipoRon (AR), 5 μM SKI-II and 5 μM THI as indicated. For all graphs the y-axis is displayed as % toxicity relative to BSA. Data represent mean ± SEM; *P < 0.05 vs PA, #P < 0.05 vs PA + AR, %P < 0.05 vs PA + SKI-II, $P < 0.05 vs PA + THI, n = 3. In another subset of cells 2.5 μM S1P added for 24 h following which d) LDH, e) MTT or f) Trypan blue was measured. For all graphs the y-axis is displayed as % toxicity relative to BSA. Data represent mean ± SEM; P < 0.05 vs PA, #P < 0.05 vs PA + AR, n = 3Back to article page
