Effects of CUR, RES and SFN on TNF-α and IL-6 protein levels in LPS/IFN- γ-stimulated RAW 264.7 macrophages. Cells were treated for 24 h with CUR, RES or SFN (5 and 20 M) in the presence of LPS (10 ng/mL) plus IFN-γ (10 U/mL) with DOX (0.1 µM). TNF-α (A) and IL-6 (B) protein levels were quantified using ELISA. Data are expressed as mean ± S.E. (n = 3). Comparisons are made with ANOVA followed by Student–Newman–Keuls (SNK) post-hoc test; *, P < 0.05, compared with control; $, P < 0.05, compared with LPS/IFN- γ plus DOX treatment.
