The expression of MMP-2, MMP-7, MMP-9 and MT1-MMP in gastric cancer cell lines MKN1, KatoIII, AGS and NCI-N87. (A) Differential mRNA expression of MMP-2, MMP-7, MMP-9 and MT1-MMP in MKN1, KatoIII, AGS and NCI-N87 was found by real-time PCR. Data are expressed as mean ± SD, n = 3, *P < 0.05. (B) Differential protein expression of MMP-2, MMP-7, MMP-9 and MT1-MMP in MKN1, KatoIII, AGS and NCI-N87 was found by Western blotting.
