KGF-induced Nrf2 nuclear translocation in A549 cells. The content of Nrf2 cytosolic and nuclear fractions was determined in the indicated subcellular fraction by western blot analysis. Cells were exposed to 20 ng/ml KGF for the indicated times. Values shown are percent of the values in untreated cells. GAPDH (cytosolic fraction) and PCNA (nuclear fraction) were used as loading controls. Mean±SE (n=3). *p<0.05 compared with control.
