Abstract:

Objective To determine the expressions of matrix metalloproteinase-11(MMP-11) and transcription factor Sp1 in colorectal carcinoma,and to investigate their relations. Methods Immunohistochemical technique was used to determine the expressions of MMP-11 and transcription factor Sp1 in 72 specimens of colorectal cancer tissues and 20 specimens of adjacent normal colorectal tissues. Results The positive expression rates of MMP- 11 and transcription factor Sp1 in colorectal cancer tissues were 63.89%(46/72) and 66.67%(48/72),and those in adjacent normal colorectal tissues were 20% and 10%(P<0.05). The expressions of MMP-11 in colorectal cancer tissues were correlated with TNM stage,differentiation degree and lymph node metastasis(P<0.05),but there was no correlation with age,sex and tumor size. MMP-11 expression was positively correlated with transcription factor Sp1 expression in colorectal cancer tissues(r=0.45,P<0.01). Conclusions MMP-11 and transcription factor Sp1 have close relations with the biological behavior of colorectal carcinoma,and it may be markers in predicting the invasion,metastasis and prognosis of colorectal carcinoma.
