Hydrolysis of triple-helical collagen peptide models by matrix metalloproteinases.
The matrix metalloproteinase (MMP) family has been implicated in the process of a variety of diseases such as arthritis, atherosclerosis, and tumor cell metastasis. To study the mechanisms of MMP action on collagenous substrates, we have constructed homotrimeric triple-helical peptide (THP) models of the collagenase cleavage sites in types I and II collagen. The THPs incorporate either the alph...

results based on the recent researches, certain mmps play critical role in breast cancer initiation, invasion, and metastasis. they can be regarded as predictive biomarkers of primary diagnosis and prognosis of breast cancer and have predictive value for evaluation of disease, tumor recurrence, invading of tumor cells to other sites and therapeutic outcomes. conclusions in summary, the results ...
متن کاملP 88: Matrix Metalloproteinases in Neuroinflammation
Matrix metalloproteinases (MMPs) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. MMPs have been demonstrated to increase the permeability of the blood–brain barrier (BBB) by degrading the c...
متن کاملMatrix metalloproteinases
What makes an MMP an MMP? They all have a conserved zinc-binding site in their catalytic domain (HEXGHXXGXXH), and the sequence PRCGVPD in the propeptide domain. The cysteine residue serves to anchor the propeptide to the catalytic zinc, suppressing enzymatic activity in a manner that is not unlike a thumb in an open mouth. Release of this interaction results in proteolytic activity. MMPs are a...
متن کاملMatrix Metalloproteinases.
Matrix metalloproteinases are a family of highly regulated peptidases that are collectively responsible for the degradation of extracellular matrix during tissue remodeling. Dysregulated activity has long been implicated in the pathologies of cancer and arthritis, and the number of diseases more recently associated with these enzymes has been increasing. In the past year, new transgenic models ...
