Effect of luteolin on Nrf2 expression in hFOB1.19 cells. Western blotting analysis of Nrf2 expression in treated hFOB1.19 cells. Nrf2 levels decreased in hFOB1.19 cells after 1, 3, and 5 days of LPS induction, and this effect was reversed by luteolin. After LPS and H2O2 induction, Nrf2 expression decreased in hFOB1.19 cells after 1, 3, and 5 days. This effect was also alleviated by luteolin. The data are expressed as the means ± SDs (**p < 0.01, *p < 0.05)
