Figure 7.

Western blot of the levels of proteins COX-2 (A) (p72), iNOS (B) (p130), and p-IκBα (p40) (C) on LPS-stimulated RAW 264.7 cells, after treatment with OADP for 72h at the ½ IC₅₀ and ¾ IC₅₀ concentrations. Protein expression levels are expressed as arbitrary intensity units for each band compared to arbitrary intensity units for actin (p45). Variations in the relative percentages of TNF-α and IL-1β expression for each concentration are also shown. The values represent means ± S.D. of at least two separate experiments. Key: (**) p < 0.01 and (***) p < 0.001, with respect to LPS-treated control cells (positive control).
