Figure 6. QGS inhibits ESCC cell invasion. (A) Invasion assays were performed by placing ECA109 and TE13 cells treated with QGS (0, 100, or 200 μg/mL) in the transwell system for 24 h; the control is shown on the left. (B) Bar graphs showing number of invading cells for each cell line after 0, 100, or 200 μg/mL QGS. Combined results from three independent experiments are shown. *p<0.05, **p<0.01, compared to control.
