Effects of QDP on LPS-induced production of TNF-α and IL-6 and expression of iNOS and COX-2 in RAW264.7 cells. Cells were treated with QDP for 1 h, followed by continuous incubation with LPS (1 μg/mL) for 24 h. a Concentrations of TNF-α and IL-6 in culture medium were monitored by ELISA. b Cells were lysed and expression of iNOS and COX-2 were determined by Western blotting. Data represent the mean ± SD (n = 3). The images shown are representatives of three independent experiments
