BACKGROUND Matrix metalloproteinase (MMP)-8 is a central mediator in chronic periodontitis. MMP-8 can be activated by the cooperative action of other MMPs such as MMP-14, reactive oxygen species, and microbial proteases. The aim of this study is to associate the levels, molecular forms, isoenzyme distribution, and degree of activation of MMP-8 and -14,(More)
PURPOSE To study extracellular matrix (ECM) metabolism by matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) in aqueous humor (AH) samples collected from primary open-angle glaucoma (POAG), exfoliation syndrome (EXS), and exfoliation glaucoma (EXG) in relation to samples derived from cataract control patients. MATERIALS AND METHODS(More)
AIM Salivary matrix metalloproteinase (MMP)-8 and -14, tissue inhibitor of matrix metalloproteinase (TIMP)-1, and pyridinoline cross-linked carboxyterminal telopeptide of type I collagen (ICTP) were analysed aiming to detect potential markers of advanced periodontitis in saliva. In addition, we compared two MMP-8 detection methods, a time-resolved(More)
Periodontal inflammation is characterized by irreversible degradation of periodontal ligament collagen fibers leading to loss of tooth attachment. Cultured gingival keratinocytes and fibroblasts express, in vitro, various matrix metalloproteinases (MMPs) which can degrade fibrillar collagens. We hypothesized that several MMPs are also synthesized in vivo by(More)
BACKGROUND Helicobacter pylori causes chronic gastritis, peptic ulcer disease, and is the most important risk factor for non-cardia gastric cancer, and has been shown to upregulate matrix metalloproteinases (MMPs) in infected gastric mucosa. MMPs are proteolytic enzymes regulated by tissue inhibitors of metalloproteinases (TIMPs). AIMS We set up this(More)
AIMS The aims of this study were to investigate (1) the matrix metalloproteinase-1 (MMP-1) promoter polymorphisms in severe chronic periodontitis (CP), (2) the relationship of periodontal therapy outcome with these genotypes, and (3) the gingival crevicular fluid (GCF) MMP-1 levels-MMP-1 genotype correlation. MATERIAL AND METHODS Genomic DNA was obtained(More)
BACKGROUND AND OBJECTIVE Matrix metalloproteinase-8 (MMP-8) is a central mediator in chronic periodontitis. Recently developed MMP-8-deficient mice show an impaired polymorphonuclear neutrophil response and more severe alveolar bone loss in Porphyromonas gingivalis-induced experimental periodontitis. The main mediators involved in neutrophil and(More)
AIM To identify the diagnostic accuracy of gingival crevicular fluid (GCF) candidate biomarkers to discriminate periodontitis from the inflamed and healthy sites, and to compare the performance of two independent matrix metalloproteinase (MMP)-8 immunoassays. MATERIALS AND METHODS Cross sectional study. GCF (N = 58 sites) was collected from healthy,(More)
Matrix metalloproteinase-8 is a promising candidate biomarker for oral fluid (gingival crevicular fluid, peri-implant sulcular fluid and saliva) and mouthrinse chair-side/point-of-care diagnostics to predict, diagnose and determine the progressive phases of episodic periodontitis and peri-implantitis, as well as to monitor the treatments and medications.(More)
