Gelatinases (MMP-2 and MMP-9) are involved in different cellular process including angiogenesis and neurogenesis; these proteases alter the molecules of the basal lamina, subsequently leading to cell death. Stromelysins (MMP-3, MMP-10, and MMP-11) are small proteases that degrade segments of the ECM.

MMP-9 is a metalloproteinase that has an important role in ECM remodeling, angiogenesis, metastasis, and cancer progression. Hence, MMP-9 inhibitors have become a potential target for anticancer drug development.

MMP-9 directly degrades extracellular matrix (ECM) proteins and activates cytokines and chemokines to regulate tissue remodeling. MMP-9 deletion or inhibition has proven overall beneficial in multiple animal models of cardiovascular disease.

Matrix metalloproteinase 9 (MMP-9) has been implicated as the major facilitator of this ECM degradation. MMP-9 is expressed by the embryo's trophoblast cells, whereas tissue inhibitor of metalloproteinases 3 (TIMP-3) is expressed by the maternal uterine …

May 15, 2020 · MMP-9 has the ability to degrade the extracellular matrix (ECM) components and has important role in the pathophysiological functions. Overexpression and dysregulation of MMP-9 is associated with various diseases.

The main group of enzymes responsible for the collagen and other protein degradation in extracellular matrix (ECM) are matrix metalloproteinases (MMPs). Collagen is the main structural component of connective tissue and its degradation is a very important process in the development, morphogenesis, t …

May 1, 2024 · In colorectal cancer, neutrophil-derived MMP-9 releases VEGF from the ECM by cleaving heparan sulfates, enhancing endothelial cell sprouting and angiogenesis, underlining MMP-9’s critical role...

May 15, 2020 · MMP-9 is one of the most complex forms of matrix metalloproteinases. MMP-9 has the ability to degrade the extracellular matrix (ECM) components and has important role in the pathophysiological functions. Overexpression and dysregulation of MMP-9 is associated with various diseases.

Jul 29, 2015 · Here we provide the first evidence that CTSK can cleave and activate MMP-9 in acidic environments such as seen in tumors and during bone resorption. This finding provides a key link between CTSK expression in tumors and bone and …

Feb 1, 2024 · MMP-9, known as gelatinase B, readily digests denatured collagen and gelatin. It is one of the most complex forms of matrix metalloproteinases. MMP-9 can process a wide range of ECM substrates. It is mainly found in the hippocampus, cerebral cortex, and cerebellum.
