Fig. 1From: Anti-inflammatory effect of oligostilbenoids from Vitis heyneana in LPS-stimulated RAW 264.7 macrophages via suppressing the NF-κB activationCOX-2 expression effects of V. heyneana extract (VH) and its fractions (VHH: n-hexane, VHE: ethyl acetate, VHW: water fraction; all 50 µg/mL). Eighteen hours after treating cells with LPS (5 µg/mL) with or without fractions in RAW 264.7 cells. Samples were harvested and lysated for COX-2 mRNA level by qPCR. Relative changes in the COX-2 mRNA expression (*significant as compared to control, *, p < 0.05; **, p < 0.01; ***, p < 0.001; #significant as compared to LPS group, n = 4–5)Back to article page
