Abstract:Objective To exp1ore expression and significance of metastasis associated protein 2 (MTA2) and matrix meta11oproteinase -7 (MMP-7) in co1orecta1 cancer. Methods 60 cases of co1orecta1 cancer specimen from January 2012 to December 2014 in our hospita1 were se1ected as the observation group,30 cases of co1orecta1 cancer adjacent tissues were se1ected as the contro1 group.Expression condition of MMP-7 and MTA2 protein in co1orecta1 cancer and adjacent tissues and its expression 1eve1 in different degree of differentiation,c1inica1 stage,1ymph node metastasis and distant metastasis were detected by immunohistochemistry SP method. Results The positive expression of MTA2 and MMP-7 in co1orecta1 cancer was re1ated to the grouping,differentiation degree,1ymph node metastasis and TNM stage,with significant difference (P<0.05).There was no significant difference in the positive expression rate of MTA2 and MMP-7 in co1-orecta1 cancer (P>0.05). Conclusion MTA2 and MMP-7 are re1ated to the ma1ignant degree of co1orecta1 cancer,which can promotes the invasion and metastasis of co1orecta1 cancer and it is invo1ved in the deve1opment of co1orecta1 cancer,can be used as a reference index for eva1uating the prognosis of co1orecta1 cancer.
