Figure 5. Effects of AA on LPS-induced activation of MAPKs and NF-κB in RAW264.7 cells.

(A) Cells were treated with AA in the absence or presence of LPS for 24 h. The protein levels of total and phosphorylated p38, JNK, ERK and IκBα were determined at least 3 times. (B) Summary data of (a) are expressed as a histogram of mean ± SD of 3 independent experiments. ^*p < 0.05 versus control, ^#p < 0.05 versus LPS group.
