Matrix Metalloproteinase- 3 (MMP-3)

Name of the Test:

Matrix Metalloproteinase- 3 (MMP-3)

Alias names:

Stromelysin-1

MMP-3 has been reported to increase,

  • Systemic lupus erythomatosis
  • Rheumatoid arthritis , especially predicting erosive disease
    • Pan Laboratories
    Pan Laboratories

    Clinical research applications:

    Matrix metalloproteinases (MMPs) are a family of Zinc and calcium dependent endopeptidases that degrade extracellular matrix proteins. Human Matrix metalloproteinase-3 (MMP-3, Stromelysin-1), may be expressed in fibroblasts, chondrocytes, osteoblasts, endothelial cells, macrophages and keratinocytes. Inflammatory cytokines such as IL-1, TNF-alpha , PGF and oncology cellular transformation markers promote the biosynthesis of MMP-3. Glucocorticosteroids, retinoic acid and estrogen suppresses MMP-3 biosynthesis. MMP-3 may participate in physiological matrix turnover and pathological destruction of the tissue. Serum level of MMP-3 appear to be an useful marker in the diagnosis of rheumatoid arthritis and also for the evaluation of prognosis of joint destruction and cartilage degradation. Increased MMP-3 in systemic lupus erythomatosis appears to be related to lupus nephritis.

    Method:

    Pan Laboratories

    MMP-3 in serum is quantitated using an ELISA (Enzyme linked immunosorbent assay) procedure. It is a two-step sandwich-type immunoassay using two antibodies to MMP-3; monoclonal antibody is the capture antibody and signal polyclonal antibody is conjugated with horse-raddish peroxidase (HRP). High concentration of MMP-3 results in high color reading at 450 nm.
