Protective roles of matrix metalloproteinases: From mouse models to human cancer

Matrix metalloproteinases (MMPs) have long been linked to cancer progression owing to their ability to breakdown tissue barriers for metastatic spread. Accordingly, multiple studies have examined the potential value of these enzymes as targets for cancer therapy. Unfortunately, most clinical trials with MMP inhibitors have yielded negative results which has made necessary to re-evaluate the role of these proteases in cancer. Recent works mainly...
