Effect of BHD, mBHD-1, and mBHD-2 on the expression of proinflammatory cytokines in LPS-exposed RAW264.7 cells. Cells were pretreated with 1, 2.5, or 5 mg/mL of each drug for 1 h and then were stimulated with LPS for 4 h. Transcriptional levels of inflammatory cytokines of IL-1β, IL-6, and TNF-α were detected using RT-PCR (a) and the protein expression of iNOS and Cox-2 was detected using western blotting (b). IL: interleukin; TNF: tumor necrosis factor; iNOS: inducible nitric oxide; Cox-2: cyclooxygenase-2; GAPDH: glyceraldehyde 3-phosphate dehydrogenase; LPS: lipopolysaccharide. C, control; ∗p < 005; ∗∗p < 0.01; ∗∗∗p < 0.001 vs. control; #p < 005; ##p < 0.01; ###p < 0.001 vs. LPS. Statistical differences were analyzed using one-way ANOVA followed by Tukey's multiple comparisons test. Error bars indicate SEM.
