Effects of different doses of Vaccaria hypaphorine (12.5, 25 and 50 μM), Dex (100 μM) and Asp (1 mM) on the mRNA expressions of TNF-α (a), IL-1β (b), IL-6 (c), IL-10 (d) and MCP-1(e) response to LPS (1 μg/ml)-treated RAW264.7 cells for 24 h in vitro. Values are mean ± S.D. *P < 0.05 vs. Control, †P < 0.05 vs. LPS, †† P < 0.05 vs. Vaccaria hypaphorine (12.5 μM) + LPS. n = 6 for each group. LPS, lipopolysaccharide; Dex, dexamethasone; Asp, aspirin; TNF-α, tumor necrosis factor-α; IL-1β, interleukin-1β; IL-6, interleukin-6; IL-10, interleukin-10; MCP-1, monocyte chemoattractant protein 1
