PURPOSE Extracellular matrix metalloproteinase inducer (EMMPRIN) has been shown to stimulate fibroblasts to production of matrix metalloproteinases (MMPs). MMPs comprise a family of proteolytic enzymes implicated in the degradation of extracellular matrix which has been proposed to be one of the essential steps in tumor invasion and metastases. In the present study we investigated the expressio...

BACKGROUND The study was undertaken to develop a potential new markers for distinguishing minimal change nephrotic syndrome (MCNS) and focal segmental glomerulosclerosis (FSGS) in children. We hypothesized that matrix metalloproteinase-9/neutrophil gelatinase-associated lipocalin (MMP-9/NGAL) is a better marker of focal sclerosis in the glomerulus then matrix metalloproteinase-9/tissue inhibito...

We aim to find a link between keratokonus (KC) and bullous keratopathy (BK), and extra cellular matrix re-modellation molecules. The activities of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), pro-matrix metalloproteinase-13 (proMMP-13) and tissue inhibitor of matrix metalloproteinases-1 (TIMP-1) were measured using immunoassay in three human corneal tissue layers (epi...

background: previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. in the current study, effects of il-4 against morphological changes and tissue degradation induced by il-1α on bovine nasal cartilage (bnc) explants were investigated. methods: fresh bnc samples were prepared from a slaughterhouse under sterile conditions. bnc explants culture was...

Multidrug resistant (MDR) cancer cells overexpressing P-glycoprotein (P-gp) display variations in invasive and metastatic behavior. We previously reported that these properties of MDR cancer cell lines overexpressing P-gp could be altered by chemotherapeutic drugs or MDR modulators (R. S. Kerbel et al., Cancer Surv., 7: 597-629, 1988). To attempt to clarify the mechanism(s) underlying these obs...

Periodontitis is typically associated with disorders characterized by compromised tooth-supporting tissue. Damage to periodontal tissue caused an imbalance between matrix metalloproteinases and their inhibitors. Decreased inhibitor elevated metalloproteinase levels result in collagen connective bone degradation. Several studies have shown that high of metalloproteinase-13 (MMP-13) low metallopr...

Introduction:Oral Squamous Cell Carcinoma (OSCC) is an invasive neoplasm with a high prevalence. Matrix Metalloproteinase (MMP) has been thought to play an important role in both the invasion and metastasis of tumors. The aim of this study was to explore the significance of MMPs expression in clinical outcome of these patients. Materials:The most recognized data Bases such as PubMed, Google sc...

Matrix metalloproteinases (MMP-) are involved in leukocyte invasion into the central nervous system (CNS) during inflammation. In a retrospective cohort study of 18 neuro-BD patients, CSF samples were studied for MMP-9, TIMP-1 and cell characteristics in neuro-BD patients compared to 12 Headache attributed to BD (HaBD) patients, 15 multiple sclerosis (MS) and 20 Non-inflammatory Neurological Di...

Endotoxin shock is a life-threatening disorder, associated with the rapid release of neutrophil enzymes, including neutrophil collagenase/matrix metalloproteinase-8 (MMP-8) and gelatinase B/matrix metalloproteinase-9 (MMP-9). After activation, these enzymes cleave extracellular matrix components and cytokines and thus may contribute to shock syndrome development. MMP inhibitors have been sugges...
