Overexpression of MMP7 promotes tongue cancer cell line growth in vitro. a-b, After transfection of the overexpression plasmid in CAL27 and SCC9 cells, the expression changes in MMP7 were tested by real-time PCR (a) and Western blotting (b). c-d, The proliferation ability of tongue cancer cells was measured by the CCK8 assay (c, p < 0.05 from 48 h to 120 h) and colony formation assay (d) after MMP7 overexpression. These experiments were repeated three times independently. * when p < 0.05, ** when p < 0.01, *** when p < 0.01
