Elevated level of circulating matrix metalloproteinase-9 in patients with lung cancer.


The 72 kDa matrix metalloproteinase (MMP-2) and the 92 kDa matrix metalloproteinase (MMP-9), are type IV collagenases that have been implicated as important factors in cancer invasion and metastasis formation. We have used quantitative zymography and computer-assisted image analysis to measure the levels of MMP-9 and MMP-2 in 19 samples of serum of lung… (More)
