Fig. 8. Forrestline F suppressed LPSinduced inflammatory activity through Nrf2 pathways and promoted the LPSinduced nuclear translocation of Nrf2. (A–B) The cells were exposed to forrestline F (5, 10, 20 μM) for 3 h and cultured with LPS for 24 h, except for the control group. The protein expression of Keap-1/Nrf2 pathway was determined by western blotting and the quantifications of protein expression were performed by Image J. (C) The inhibitory effect of forrestline F (20 μM) on the nuclear translocation of Nrf2 induced by LPS via confocal laser scanning microscopy, in conjunction with nuclear DAPI stain (scale bar: 50 μM). The values are presented as mean ± SD of three independent experiments, n = 3. ###p <0.001, vs. the control group; ***p
