Protein expression levels of HO-1 regulator proteins in H9c2 cells using western blot method. (A) Western blotting analysis and quantitative analysis of (B) Keap1, (C) Nrf2, (D) HO-1, (E) IKK and (F) NF-κB in H9c2 cells. Data are presented as the mean ± SD. Each experiment was repeated three times independently. *P<0.05 vs. NC group. #P<0.05 vs. OT group. DHE, dehydrocostus lactone; TXNIP, thioredoxin-interacting protein; NC, negative control; OT, DHE treatment group; OI, DHE treatment combined with TXNIP inhibition group; OH, DHE treatment combined with TXNIP overexpression group; Nrf2, nuclear factor erythroid 2-related factor 2; HO-1, heme oxygenase-1; Keap1, Kelch-like ECH-associated protein 1; MW, molecular weight.
