Behavior of cancer cells is profoundly affected by their microenvironment, which is often controlled by pericellular proteolysis or the processing of protein components, including extracellular matrices, growth factors, cytokines, receptors, cell adhesion molecules, and so on. Matrix metalloproteinases (MMPs) are a family of zinc‐dependent proteases responsible for the proteolytic events in the extracellular milieu. Among the multiple MMPs expressed in a wide range of tumors, membrane type‐1 MMP (MT1‐MMP), which is expressed especially in tumor cells with significant invasive properties, is thought to be particularly important for pericellular proteolysis. Recent studies have elucidated in part how MT1‐MMP is regulated biologically for the promotion of invasion by tumors or for angiogenesis by endothelial cells. Understanding of the proteolysis by, and the regulation of MT1‐MMP, which probably promotes cell invasion, could provide a therapeutic hint as to how to block or delay the progression of cancer.
