a) WT and MKK3 −/− mice were given IP LPS (40mg/ml) and malondialdehyde (MDA) levels were measured in serum (n=5–8, Mean +/− SEM are shown, *p<0,05)
b) WT and MKK3 −/− lung endothelial cells were exposed to LPS (1μg/ml). Cells were stained with CM-H2DCFDA, which detects H2O2, levels were measured by flow cytometry. The values are expressed as mean fluorescent intensity +/− SEM (p<0.05). The results are representative of at least 3 independent experiments. Representative fluorescence histograms of LPS exposed cells are shown.
c) WT and MKK3 −/− lung endothelial cells were exposed to LPS (1μg/ml). Cells were stained with Mitosox red, which detects mitochondrial ROS, levels were measured by flow cytometry. The values are expressed as mean fluorescent intensity +/− SEM (p<0.05). The results are representative of at least 3 independent experiments. Representative fluorescence histograms of LPS exposed cells are shown.
