WA inhibits the invasive activity of AGS cells in vitro. (A) The effect of WA on the invasive ability of AGS cells treated with 0, 1, 2.5 and 5 µM WA for 24 h was evaluated using a Boyden chamber assay. Representative images of the Boyden chamber assay were captured at ×40 and ×100 magnification. (B) Cell invasion was quantified following treatment with various concentrations of WA for 24 h. Results are presented as the mean ± standard error of the mean (n=3). *P<0.01, **P<0.001; ***P<0.0001 vs. control.
