Abstract:
Matrix metalloproteinases (MMPs) are a family of proteolytic enzymes, which perform a crucial role in the metastatic spread of cancer. MMP2 and MMP9 are important cancer-associated MMPs in the invasion and metastasis of the majority of carcinomas. As a new member of the membrane-type MMPs, the function of MMP16 associated with invasion and metastasis of cancer remains unclear. In the present study, MMP16 expression in prostate cancer (PCa) tissues and cells was examined, and the high expression of MMP16 was revealed to be associated with advanced prostate tumor stage and PCa cell metastasis. The membrane localization of MMP16 is required for its function. To the best of our knowledge, the present study is the first to demonstrate that MMP16 is associated with advanced prostate tumor stage. As an important mediator of PCa cell metastasis, the membrane localization of MMP16 is required, and MMP16 may be an ideal target candidate for preventing PCa cell metastasis.
Insights
Matrix metalloproteinases (MMPs) are key in cancer spread. This study finds that MMP16, a membrane-type MMP, is linked to advanced prostate cancer stages and metastasis, suggesting it as a therapeutic target.
Area of Science:

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
