Objective:To investigate the expression of DDR1a and the activities of MMP2
MMP9 in colon carcinoma cells and their mutual relations.Methods:The expression of DDR1a in colon carcinoma cell and human colon smooth muscle cell was detected by Western blot
the activities of MMP2
MMP9 were examined by gelatin zymography analysis.Results:The expression of DDR1a and the activities of MMP2
MMP9 in colon carcinoma cell(LOVO)which has stronger invasive behavior were significant higher(P<0.01).There was significant positive correlationship between the expression of DDR1a and the activities of MMP2
MMP9 in tested cells(P<0.05).Conclusion:DDR1a may act as one of biological indicators of the invasion in colon carcinoma cells.
