Elevated expression of their activity, caused either by up-regulation of their expression or down-regulation of their cognate inhibitors, has been implicated in various degenerative disorders, including arthritis, cardiovascular diseases, skeletal growth-plate disorders, and cancer metastasis. MMP-1 is a secreted collagenase with specificity toward Type I, II, III, VII, and X collagens, aggrecan, serpins, and α2-macroglobulin. It is overexpressed in lumbar intervertebral disc degeneration (IDD). It might also be associated with rheumatoid arthritis and osteoarthritis. MMP-1 is linked with juvenile idiopathic arthritis. Genetic variations in MMP-1 can affect the susceptibility and severity of this disease. MMP-1 might facilitate fibrous plaque disruption via degradation of interstitial collagens and thinning of the fibrous cap._x000D_ Other Notes_x000D_ A sample Certificate of Analysis is available for this product._x000D_ Please type the word sample in the text box provided for lot number.
