Markers of LPS-induced oxidative stress. Effect of LPS on protein carbonyl expression level (A), RPT1 protein expression level (B) and proteasome 20S α + β protein expression level (C) in the GAS of mice 8 hours after administration of LPS 7.5 mg/kg with or without epoxomicin 0.5 mg/kg treatment. Samples of each blot were ran on the same gel. Values are means ± SEM. * p < 0.05, *** p < 0.001 compared with control (C); #
p < 0.05 compared with LPS (L).
