Effects of daidzin and daidzein on iNOS and COX-2. A Representative Western blots, and B, C summarized data for protein expressions of iNOS and COX-2 in RAW264.7 cells pretreated with daidzin (50 µM), daidzein (50 µM) and DXMS (5 µM, positive control) for 4 h and co-treated with LPS (1 µM) for another 12 h. Values are the means ± SEM (n = 4); *p < 0.05, **p < 0.01, daidzin vs. LPS and daidzein vs. LPS; ^##p < 0.01, ^###p < 0.001, LPS vs. control
