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

Table 2 Expression of MMP-1 mRNA in samples from patients with different severity of UC (mean ± SD)

Samples	MMP-1 mRNA	TNF-α mRNA	P value
Ulcerated area	0.9797 ± 0.1433	0.8669 ± 0.0746	< 0.05ace
Inflamed area	0.6746 ± 0.0373	0.5227 ± 0.0435	< 0.05ac
Non-inflamed area	0.0071 ± 0.0025	0.0302 ± 0.0299	< 0.05
