The overexpression membrane type 1 matrix metalloproteinase is associated with the progression and prognosis in breast cancer.

ABSTRACT: Membrane type 1 matrix metalloproteinase (MT1-MMP) has been demonstrated to play an important role in tumor progression. The aim of the present study was to analyze the expression of MT1-MMP in breast cancer and its correlation with clinicopathologic characteristics, including the survival of breast cancer patients. In our results, MT-MMP1 was up-expressed in breast cancer tissues compared with ductal hyperplasia tissues in microarray data (GSE2429). MT1-MMP mRNA and protein expression was markedly higher in breast cancer tissues than in normal breast tissues (P=0.005 and P=0.037, respectively). Using immunohistochemistry, high levels of MT1-MMP protein were positively correlated with the status of clinical stage (I-II vs. III-IV; P=0.043), lymph node metastasis (absence vs. presence; P=0.
