Introduction:
Current treatment of fibrosarcoma, an aggressive cancer of the connective tissue, is generally associated with poor prognosis. Matrix metalloproteinases (MMPs), vascular endothelial growth factor (VEGF), and constituents of the ECM, such as fibronectin, play a critical role in angiogenesis and underlie neoplastic invasion and metastasis. This and anticancer properties of lysine, proline, arginine, ascorbic acid, and green tea extract (NM) prompted us to investigate the effect of these nutrients in vitro on human fibrosarcoma cells HT-1080 by measuring: cell proliferation, modulation of MMP-2 and MMP-9, and invasive potential.

Abstract:
Matrix metalloproteinases (MMPs) have received much attention in recent years for their role in various malignancies, and have been implicated in tumor invasion, metastasis and angiogenesis. Certain MMPs, such as MMP-2 and MMP-9, have shown a special propensity for promoting cancer. Development of MMP inhibitors has been a recent approach to controlling cancer and blocking metastasis.
