Figure 5

Nuclear factor erythroid-2 related factor 2 (Nrf2) nuclear expression is upregulated and NLR family pyrin domain-containing 3 (NLRP3)/thioredoxin-interacting protein-thioredoxin1 (TXNIP) is down-regulated after SalB treatment in H/R (A–C) NLRP3 and TXNIP expression were examined by western blot. (D) Immunofluorescence results (magnification ×400) showing the expression of Nrf2 under normal conditions (control), SalB treatment and H/R-treated HK-2 cells. Blue, nuclear staining (DAPI); red, Nrf2 staining. Scale bar: 20 μm. (E) Representative western blots and (F–H) quantification of relative protein expression for nuclear Nrf2, keap1 and HO-1. (I) Representative images of fluorescence of ROS probed by DCFH-DA. Data are represented as images or expressed as the mean ± SEM of each group from three separate experiments. **p < 0.01 vs. control group; #p < 0.05, ##p < 0.01 vs. H/R group.
