Hoveniae Semen Seu Fructus Ethanol Extract Exhibits Anti-Inflammatory Activity via MAPK, AP-1, and STAT Signaling Pathways in LPS-Stimulated RAW 264.7 and Mouse Peritoneal Macrophages

Figure 4

Effects of hoveniae semen seu fructus ethanol (HSFE) extract on phosphorylation of (a) ERK, (b) p38, and (c) JNK mitogen-activated protein kinases in macrophages. Cells were seeded with on a 6-well culture plate and preincubated for 18 h. Then, cells were treated with HSFE for 1 h and stimulated with LPS for another 30 min. At least three independent tests were repeated to ensure reproducibility. Total ERK, p38, and JNK served as the controls for their phosphorylated forms. Data in the histograms show protein expression levels relative to those of total-type protein. The results shown are representative of three separate experiments. Con: control.
