Effect of PP on HO-1 induction in THP-1 cells. HO-1 was detected after treatment with PP (5–20 μg/mL) in the THP-1 cells for 20 h (a). Nrf-2 was detected after treatment with PP (5–20 μg/mL) in the THP-1 cells for 30 min (b). The expression levels of each protein were determined using western blot and data are expressed as the mean ± SD. and versus control group.
