Moreover, MMP2 and MMP9 protein expression were tested in order to investigate the anti-metastasis potential of the CAt extract, and we found that the CAt extract repressed the expression of both MMP2 and MMP9, suggesting that the CAt extract might have the potential to suppress HCC invasion by inhibiting MMP2 and MMP9 protein expression (Figure 7B). The gene discussed is MMP2; the disease is hepatocellular carcinoma.
