Progress on the role and mechanism of MT1-MMP in tumor metastasis.

The matrix metallopeptidase family (matrix metallopeptidase, MMPs) is a class of zinc-dependent endopeptidases that can degrade most extracellular matrices. MT1-MMP (membrane type 1 metalloprotease) is an important metallopeptidase, which is located on plasma membrane and highly expressed in most tumors. MT1-MMP promotes cancer metastasis through affecting the extracellular matrix remodeling, angiogenesis, lipid metabolism, and inflammation. However, the mechanisms of MT1-MMP in different tumors have not been fully elucidated. In this review, we summarize the latest progress and the metastasis-promoting regulatory mechanisms of MT1-MMP in different tumors, which will provide references for its in-depth research and application in the field of cancer biology.
