From: Tissue levels of active matrix metalloproteinase-2 and -9 in colorectal cancer
A comparison of MMP activity in CRC tumour (n=73), transitional tissue (T–N, n=33) and normal mucosa (n=73). Data are shown for active MMP-2 (A), proMMP-2 (B), active MMP-9 (C) and proMMP-9 (D). Horizontal bars represent the median values, boxes represent the interquartile range, vertical lines represent the 10 to 90% range of the observations. Enzyme activity, as measured by quantitative zymography, is expressed as specific activity in arbitrary units per milligram protein. Significant differences with normal mucosa: **P<0.001; *P<0.01.
