Attenuation of dextran sodium sulphate induced colitis in matrix metalloproteinase-9 deficient mice

Figure 6 Activity of gelatinases in Caco-2 cells in absence (control) or presence of TNF-α (1 μg/L or 10 μg/L). A: Representative zymogram of gelatinases with molecular weights of 72 and 92 kDa corresponding to pro-MMP-2 and pro-MMP-9, respectively, were detected. Supernatants of HT1080 cells were used as controls. B: Representative immunoblot of pro-MMP-9 (92 kDa) protein in Caco-2 cells as above. C: Quantitative zymographic analysis (^aP < 0.05 vs control). D: Quantitative western-blot analysis (^aP < 0.05 vs control) (n = 3 in each group).
