Aberrant activation of matrix metalloproteinases (MMPs) is a common feature of pathological cascades observed in diverse disorders, such as cancer, fibrosis, immune dysregulation, and neurodegenerative diseases. MMP-9, in particular, is highly dynamically regulated in several pathological processes. Development of MMP inhibitors has therefore been an attractive strategy for therapeutic interven...
Cashew nut shell liquid (CNSL) has been used in traditional medicine for the treatment of a wide variety of pathophysiological conditions. To further define the mechanism of CNSL action, we investigated the effect of cashew nut shell extract (CNSE) on two matrix metalloproteinases, MMP-2/gelatinase A and MMP-9/gelatinase B, which are known to have critical roles in several disease states. We ob...
Culturing DOV 13 ovarian carcinoma cells on three-dimensional collagen lattice but not on thin-layer collagen induces processing of promatrix metalloproteinase (MMP)-2 to a M(r) 62,000 form, suggesting that multivalent integrin aggregation may participate in proteinase regulation. To address the role of collagen-binding integrins in this event, we treated DOV 13 cells with soluble beta1 integri...
Matrix metalloproteinases (MMPs) are zinc-dependent endopeptidases that cleave and degrade a wide spectrum of extracellular matrix components. By enhancing turnover of extracellular matrix, MMP activity is also known to play a key role in tumor cell invasion. Because extracellular protease activity requires efficient release of these proteases to the cellular surface, we investigated storage, t...
Matrix Metalloproteases (MMPs) and cytokines have been involved in the pathogenesis of multiple sclerosis (MS). However, no studies have still explored the possible associations between the two families of molecules. The present study aimed to evaluate the contribution of active MMP-9, active MMP-2, interleukin- (IL-) 17, IL-18, IL-23, and monocyte chemotactic proteins-3 to the pathogenesis of ...
The role of matrix metalloproteinase-2 and matrix metalloproteinase-9 in antibody-induced arthritis.
Matrix metalloproteinases (MMPs) are a large group of enzymes responsible for matrix degradation. Among them, the family of gelatinases (MMP-2/gelatinase A and MMP-9/gelatinase B) is overproduced in the joints of patients with rheumatoid arthritis. Because of their degradative effects on the extracellular matrix, gelatinases have been believed to play an important role in progression and cartil...
Matrix metalloproteinases (MMP) play an important role in pathogenesis of inflammatory bowel disease (IBD). Two known gelatinases, MMP-2 and MMP-9, are upregulated during IBD. Epithelial-derived MMP-9 is an important mediator of tissue injury in colitis, whereas MMP-2 protects against tissue damage and maintains gut barrier function. It has been suggested that developing strategies to block MMP...
BACKGROUND Matrix metalloproteinase-9 could exhibit an important role in the destabilization of atherosclerotic carotid plaques. We hypothesized that in patients with carotid stenosis, elevated levels of plasma matrix metalloproteinase-9 are associated with ipsilateral stroke or cardiovascular death. METHODS AND RESULTS We followed up 207 patients with > or = 50% carotid stenosis initially fo...
