1,2,3,4,6-penta-O-galloyl-β-D-glucose up-regulates heme oxygenase-1 expression by stimulating Nrf2 nuclear translocation in an extracellular signal-regulated kinase-dependent manner in HepG2 cells

Figure 3 Effects of PGG on Nrf2 nuclear translocation in HepG2 cells. A: After 2-h treatment with 20 µmol/L PGG; B: Cytoplasmic and nuclear extracts harvested from control cells and cells treated for indicated times with 20 µmol/L PGG, and Western blotting performed with antibodies for Nrf2, tubulin and lamin B.
