Fig. 4. Effects of 18α-GAMG on LPS-induced iNOS and COX-2 gene expression in the RAW264.7 cells. The cells were treated with different concentrations of 18α-GAMG and then in the presence or absence of LPS (1 μg mL^–1) for 20 h. Bay 11-7082 is the NF-κB inhibitors (20 μM). The results have been shown as means ± SD (n = 3) of at least three independent experiments. ^#p < 0.05, ^##p < 0.01, ^###p < 0.001 compared with the control group; * p < 0.05, ** p < 0.01, *** p < 0.001 compared with LPS-stimulated group.
