MMP9 and hepatocellular carcinoma: We showed that TARBP2 has an effect on progression of HCC, but whether the other classical proliferation, migration, and invasion markers, such as Ki-67, E-cadherin, vimentin, MMP7, MMP9, and Zeb1/2 could be affected in sh-TARBP2 and oe-TARBP2 cells was not assessed.
