Only 9 μM of DCL decreases the phosphorylation of MAPK in LPS/IFNγ-exposed RAW264.7 macrophages. RAW264.7 cells were treated with DCL (1, 3, and 9 μM), PD (PD98059, 5 μM), SB (SB208530, 5 μM), and SP (SP600125, 5 μM) for 2 h, and subsequently stimulated by LPS/IFNγ for additional 30 min. The phosphorylation of ERK, JNK, and P38 were measured by western blotting. The densitometry analysis of p-ERK (A), p-JNK (C), and p-P38 (E), normalized against total ERK, JNK, and P38 proteins. Data are represented mean ± SEM, n = 3. # p < 0.05, ## p < 0.01, ### p < 0.001, #### p < 0.0001 compared to CK group. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 compared to LPS/IFNγ group.
