Effects of GFE on the antioxidant pathway in HaCaT cells. (a) Cells were treated with GFE (10, 100 μg/ml) for 30 min (to measure Nrf2 expression) or for 24 h (to measure HO-1 and NQO-1 expressions). Expressions of Nrf2, HO-1, and NQO-1 were determined by western blot. (b) Densitometry analysis of the expressions of Nrf2, HO-1, and NQO-1. Data are presented as mean ± SD (n = 3). vs. normal controls.
