Matrix metalloproteinases (MMPs) are a group of endopeptidases with capacity to cleave components of extracellular matrix, such as collagen and elastin. The ability to modify the tissues is important for several aspects of normal and abnormal physiology. Approximately 20 different MMPs are identified, and they can be subdivided into different groups according to which components of the extracel...
background: leukemia is a malignant proliferative disorder of the hematopoietic cells. the important role of angiogenesis in leukemia has been reported by several studies. matrix metalloproteinases (mmps) are a large group of endopeptidases which degredate the extracellular matrix and play an important role in angiogenesis. objective: the present study was conducted to evaluate the patterns of ...
Matrix metalloproteinases (MMPs) are a family of zinc-dependent proteolytic enzymes that degrade extracellular matrix (ECM) components like collagen, fi bronectin, and laminin. While this activity is important for normal development, morphogenesis, and wound healing, deregulation of MMP activity has been implicated in a number of cardiovascular diseases, including congenital heart defects, athe...
BACKGROUND Matrix Metalloproteinases (MMPs) are key molecules for tumor growth, invasion and metastasis. Over-expression of different MMPs in tumor tissues can disturb the homeostasis and increase the level of various body fluids. Many MMPs including high molecular weights (HMWs) were detected in the urine of prostate and bladder cancer patients. Our aim here is to assess the usefulness of HMW ...
Cancer metastasis is tightly regulated by the interaction of tumor cells and host organ microenvironments. Matrix metalloproteinases (MMPs), produced by both tumor cells and host stromal cells, play a central role in tumor invasion and angiogenesis. We determined whether metastatic potential of lung cancer to multiple organs is dependent solely on the expression of MMPs by tumor cells, using tw...
Background/Aims—Calprotectin, a 36 kDa protein present in neutrophil cytoplasm, has antimicrobial and apoptosis inducing activities, which are reversed by the addition of zinc. Matrix metalloproteinases (MMPs), a family of zinc dependent enzymes, are important in many normal biological processes including embryonic development, angiogenesis, and wound healing, but also pathological processes su...
BACKGROUND/AIMS Calprotectin, a 36 kDa protein present in neutrophil cytoplasm, has antimicrobial and apoptosis inducing activities, which are reversed by the addition of zinc.

BACKGROUND Matrix metalloproteinases (MMPs) are activated in dilated failing hearts, and angiotensin-converting enzyme (ACE) inhibition prevents left ventricular (LV) dilatation. However, it remains unclear whether activation of MMPs precedes or is secondary to LV remodeling, and an effect of ACE inhibition on MMPs is unknown. METHODS AND RESULTS Dahl salt-sensitive rats fed a high-salt diet ...
Lung injury is one of the pathological features in human or animal after radiation and the main side effect for patient after lung cancer radiotherapy. The efficient protective strategy still needs to exploit and the underlying mechanisms remain to be investigated. We found that the expression and activity of matrix metalloproteinases (MMPs) significantly increased at the early stage of radiati...
Atherosclerosis continues to cause considerable morbidity and mortality in the Western countries. In response to cardiovascular risk factors, a cascade of compensatory structural events occurs within the vessel wall. It has become increasingly evident that significant alterations in the structure and composition of the extracellular matrix (ECM) play a key role in the atherogenic process. Far f...
