Expression of MMP-7, MMP-9, TIMP-1 and TIMP-2 mRNA in lung tissue of patients with non-small cell lung cancer (NSCLC) and benign pulmonary disease.

Abstract

Significantly higher expression of MMP-7 and MMP-9 in tumor tissue than in the surrounding tissue or in benign lung disease tissue supports the notion of an important role of these metalloproteinases in the growth of lung carcinoma. TIMP-1 expression is increased only in carcinoma, but not in benign lung disease.
