Figure 3. QGS inhibits EMT in esophageal cancer cells. (A–C) Immunofluorescence images showing E-ca, N-ca, and Snail1 localization in ECA109 cells. QSG dose-dependently increased E-ca expression and inhibited N-ca and Snail1 expression. (D–F) Immunofluorescence images of E-ca, N-ca, and Snail1 in TE13 showing the same trend after QSG stimulation. Scale bars indicate 10 μm.
