Fig. 4From: Anti-inflammatory components isolated from Atractylodes macrocephala in LPS-induced RAW264.7 macrophages and BV2 microglial cellsThe effect of 8-epiasterolid on the LPS-induced production of PGE2 in RAW264.7 (A) and BV2 cells (B). Cells were pre-treated with or without the indicated concentrations of 8-epiasterolid for 3 h, and then stimulated with LPS (1 μg/mL) for 24 h. The level of PGE2 was quantified by ELISA. Values shown are means ± SD of three independent experiments. Experimental data are considered statistically significant at values. **p < 0.01 and ***p < 0.001 in comparison with the LPS groupBack to article page
