Abstract

Many enzymes capable of proteolytic degradation of extracellular matrix and basement membranes have been implicated in tumor progression, including the matrix metalloproteinases, cathepsins, plasminogen activators, and heparanase. Matrix metalloproteinases, a family of zinc-dependent proteases, participate in several steps in tumor progression, including invasion, metastasis, and angiogenesis. In this review, we will give a brief overview of this protease family, and we will review in vitro and in vivo evidence implicating a particular metalloproteinase, the 92-kD type IV collagenase/gelatinase (MMP-9 or gelatinase B), as well as other metalloproteinases, in cancer progression. Finally, using recent studies from our laboratory, we will demonstrate the importance of both tumor cell and host stromal cell production of MMP-9 in tumor progression.
