Fig. 4. Inhibitory effects of polyphenols on phosphorylation of MAPKs [ERK1/2 (A) and JNK (B)] and NF-κB in LPS-induced RAW 264.7 cells. Cells were treated with indicated concentrations of polyphenols for 3 h, followed by induction with 1 μg mL−1 LPS for 1 h. The blots shown are representative of three blots yielding similar results.
