Ethanol Extracts of Fruiting Bodies of Antrodia cinnamomea Suppress CL1-5 Human Lung Adenocarcinoma Cells Migration by Inhibiting Matrix Metalloproteinase-2/9 through ERK, JNK, p38, and PI3K/Akt Signaling Pathways
Figure 7
Effects of EEAC on protein levels of MAPK signaling and phosphorylated focal adhesion kinase (p-FAK) in CL1-5 cells. (a) CL1-5 were treated with several different concentrations of EEAC (0.125, 0.25, 0.5, and 1.0 μg/mL) for 36 h. (b) Effects of PI3K inhibitor (LY294002; 50 μM), ERK1/2 inhibitor (PD98059; 50 μM), JNK inhibitor (SP600125; 50 μM), and p38 MAPK inhibitor (SB203580; 50 μM) on EEAC-induced protein expressions of MMP-2 and -9. Cells were pretreated with an inhibitor (50 μM) at 1 h prior to the treatment with 1.0 μg/mL EEAC for 36 h (total inhibitor exposure time was 37 h). Protein expressions of MMP-2 and -9 were determined by the western blotting assay.
