Representative Western blot analysis of PPAR-γ in protein extracts from HSCs and ISEMFs treated with plasma and incubated for 4 hrs. As indicated, cells were pre-treated with NAC. Similar results were obtained in three independent experiments. β-actin was used as a loading control (panel A). Cells were treated for 30 min with 50 µM PPAR-γ receptor antagonist T0070907, exposed to plasma, and then incubated under standard conditions for 24 hrs. IL-6 (panel B) and IL-1β (panel C) were assessed in the conditioned medium by ELISA. Data are reported as mean±SE of results collected in nine independent experiments, each performed in triplicate. * denotes P<0.05 vs non treated cells.
