The extracellular signal-regulated kinase (ERK) and the protein kinase B (Akt) signaling pathways are affected by 3-BDB (30 µM) treatment. (a) After treatment with 3-BDB, total protein lysates were collected and analyzed for the levels of phospho-Akt, Akt, phospho-ERK1/2, and ERK1/2 with Western blotting using specific antibodies. (b) HO-1 and (c) phospho-Nrf2 levels were analyzed via Western blotting. U0126 and LY294002 are an ERK inhibitor and a PI3K inhibitor, respectively. * Significant difference compared with control (p < 0.05); ** significant difference compared with 3-BDB-treated cells (p < 0.05).
