Objective:Evidence is accumulating that synovial tissue plays an active role in osteoarthritis (OA), however, exact understanding of its contribution is lacking. In order to further elucidate its role in the OA process, we aimed to identify the secretion pattern of soluble mediators by synovial tissue and to assess its ability to initiate...

Aims Atherosclerotic plaque rupture and subsequent thrombus formation are the major cause of acute cardiovascular events. Local plaque markers may facilitate detection of the vulnerable plaque and help identify the patient at risk for cardiovascular events. Matrix metalloproteinases (MMPs) are prevalent in the arterial wall throughout the...

Several studies have shown that reduced amyloid-β 1-42 (Aβ {42}) and increased tau levels in cerebrospinal fluid (CSF) reflect increased Alzheimer's disease (AD) pathology in the brain. β-site APP cleaving enzyme (BACE1) is thought to be the major β-secretase involved in Aβ production in the brain, and therefore we investigated the relation...

Matrix metalloproteinases (MMPs) may play a pathophysiological role in the development of diabetic nephropathy (DN). We hypothesized that urinary MMP activity in patients with type 2 diabetes mellitus (T2DM) is related to a decline in renal function. We determined MMP-2, -8 and -9 activity in 24-h urine collections in relation to risk factors...

Transforming growth factor-β1 (TGF-β1), a cytokine involved in various stages of cancer, is produced as a latent complex and requires processing to become active. We have determined total and active TGF-β1 levels in homogenates of colorectal neoplasia. In contrast to total TGF-β levels, showing a stepwise increase in the mucosa-adenoma-carcinoma...

Background: Matrix metalloproteinase-9 (MMP-9) is thought to play a central role in abdominal aortic aneurysm (AAA) initiation. Doxycycline, a tetracycline analogue, has direct MMP-9-inhibiting properties in vitro, and it effectively suppresses AAA development in rodents. Observed inhibition of AAA progression, and contradictory findings in...

Transforming growth factor-β1 (TGF-β1), a tumour suppressing as well as tumour-promoting cytokine, is stored as an extracellular matrix-bound latent complex. We examined TGF-β1 activation and localisation of TGF-β1 activity in gastric cancer. Gastric tumours showed increased stromal and epithelial total TGF-β1 staining by immunohistochemistry....

Background: Previous studies have shown an upregulation of matrix metalloproteinases (MMPs) in intestinal tissue of patients with inflammatory bowel disease (IBD) and significant clinical improvement after administration of the anti-TNF-α antibody infliximab. The aims of our study were to determine expression and secretion of MMP-1, -2, -3, -9,...

Giant cell tumor (GCT) of bone is a neoplasm of bone characterized by a localized osteolytic lesion. The nature of GCT is an enigma and the cell type(s) and protease(s) responsible for the extensive localized clinicoradiological osteolysis remain unresolved. We evaluated protease expression and cellular distribution of the proteolytic machinery...

Matrix metalloproteinases (MMPs) are believed to be pivotal enzymes in the invasion of articular cartilage by synovial tissue in rheumatoid arthritis (RA). Here, we investigated the effects of gene transfer of tissue inhibitors of metalloproteinases (TIMPs) on the invasiveness of RA synovial fibroblasts (RASF) in vitro and in vivo. Adenoviral...

Many epidemiological studies suggest that elevated plasma fibrinogen concentrations form one of the most important independent risk factors in blood for cardiovascular disease and particularly atherosclerosis in humans. To clarify the effect of genetic factors, diets and their interactions on plasma fibrinogen concentrations, we examined plasma...

Background - Smooth muscle cell migration, in addition to proliferation, contributes to a large extent to the neointima formed in humans after balloon angioplasty or bypass surgery. Plasminogen activator/plasmin-mediated proteolysis is an important mediator of this smooth muscle cell migration. Here, we report the construction of a novel hybrid...

Matrix metalloproteinases (MMPs) are involved in tumor growth and metastasis, promoting the migration and invasion of cells. In this study, the amount of MMP-2 and MMP-9 activity was measured in urine from superficial bladder carcinoma patients (pTa, pT1) to evaluate their possible diagnostic value. The active and total amount of MMP-2 and MMP-9...
