Expression of matrix metalloproteinase-1 and tumor necrosis factor-α in ulcerative colitis

Table 3 Expression of MMP-1 and TNF-α proteins in samples from different areas of colon of UC patients (mean ± SD)

Samples	MMP-1	TNF-α	P value
Ulcerated area	0.0891 ± 0.0062	0.0903 ± 0.0054	< 0.05ace
Inflamed area	0.0791 ± 0.0047	0.0832 ± 0.0028	< 0.05ac
Non-inflamed area	0.0047 ± 0.0040	0.0036 ± 0.0013	> 0.05
Normal controls	0.0048 ± 0.0016	0.0029 ± 0.0021

^aP < 0.05 vs non-inlamed area;

^cP < 0.05 vs normal controls;

^eP < 0.05 vs inflamed area.
