MMP9 and hepatocellular carcinoma: Silencing RPLP1 decreases the levels of vimentin, Snail, Slug, N‐cadherin, MMP‐2, and MMP‐9, while increasing the levels of β‐catenin, E‐cadherin, claudin‐1, and tissue inhibitors of metalloproteinase-1(TIMP‐1), which are all essential components linked to EMT, eventually inhibit proliferation of HCC [103].
