Expression of matrix metalloproteinase-1 and tissue inhibitor of metalloproteinase-1 in ulcerative colitis

Table 1 Expression of MMP-1 mRNA in samples form different areas of colon in UC (mean±SD)

Samples	MMP-1 mRNA	P value
Ulcerated area	0.4136 ± 0.2495	< 0.001bd
Inflamed area	0.1491 ± 0.0891	< 0.001bd < 0.05a
Non-inflamed area	0.0102 ± 0.0144	> 0.05
Normal controls	0.0051 ± 0.0086

^bP < 0.001 vs normal controls,

^dP < 0.001 vs non-inflamed area,

^aP < 0.05 vs ulcerated area.
