Our results revealed that the invasive and migratory potential of TGF-β1-treated HCC cells was remarkably higher than that of control cells at 24 h, while isoviolanthin (2.5 μM, 5 μM, and 10 μM) obviously attenuated TGF-β1-induced HCC cell migration and invasion in a dose-dependent manner (Figure 3A,B, p < 0.05). Here, TGFB1 is linked to hepatocellular carcinoma.
