Cell viability was detected by CCK8 and cell proliferation was detected by colony formation assay. Cell migration was detected by cell wound healing experiment and transwell chamber assay. Cell apoptosis was detected by flow cytometry. Apoptosis-related proteins (Bax, Bcl-2, PARP), migration related proteins (E-cad, N-cad, Vimentin, MMP9) and signaling pathway related proteins (TGF-β, Smad3, p-smad3) were detected by western blot. The results show that different concentrations of TF1 could inhibit the proliferation and migration of Bel-7402 cells and promote their apoptosis in a dose-dependent manner. The higher the dose, the stronger the inhibition effect (P<0.05). Compared with the control group, the expression levels of Bax and E-cad proteins in the experimental group were higher, while the expression levels of Bcl-2, PARP, N-cad, Vimentin, MMP9, TGF-β, Smad3 and p-smad3 were lower (P<0.05). In conclusion, TF1 could inhibit the proliferation and migration of Bel-7402 cells and promote their apoptosis through TGF-β signaling pathway.
