miR-199a-3p regulates extracellular matrix remodeling by targeting MMP2. (a) 3′-UTR-reporter-luciferase assay of MMP2 in HepG2 cells co-transfected with control vector and premiR-199a-3p. (b) MMP2 activity was determined by gelatin zymography in LX2, SNU449 and HepG2. (c) Western blot and (d) gelatin zymography of LX2 cells either transfected with premiR-199a-3p or control vector. **P<0.01
