Role of Nrf2 in the 3-BDB (30 µM)-mediated enhancement of Nrf2 and HO-1 expression. (a) HaCaT cells were transfected with shRNA-control and shRNA-Nrf2 plasmids and treated with 3-BDB. Western blotting was used to analyze the proteins in the whole cell lysates. (b) Nrf2-WT or Nrf2-deficient mouse embryonic fibroblast (MEF) cells were treated 3-BDB, and Western blotting was used to measure the levels of HO-1 and Nrf2. * Significant difference compared with control (p < 0.05); ** significant difference compared with 3-BDB-treated cells (p < 0.05).
