Clinical Significance
Matrix metalloproteinases (MMPs) are a family of Zinc-dependent endopeptidases that degrade extracellular matrix proteins. Human MMP-9 Matrix metalloproteinase-9 (Gelatinase-B), with a molecular weight of 82 Kd, is inhibited by TIMP-1 and alpha 2 macroglobulin. MMP-9 is secreted by tumor cells, endothelial cells, fibroblasts and leucocytes.MMP-9 is involved in inflammation, tissue modeling, wound healing and processing of cytokines. Expression of MMP-9 correlates with abnormal collagen deposition that accompanies pancreatic cancer, with the metastasis to lymph nodes by human breast cancer cells and invasion of regional vessels in giant cell tumors of bones. MMP-9 is elevated in saliva in patients with gingivitis and periodontal diseases.
