BACKGROUND Sclerosing peritonitis (SP) and encapsulating peritoneal sclerosis (EPS) are serious complications of continuous ambulatory peritoneal dialysis. Although we have shown previously that matrix metalloproteinase-2 (MMP-2) is increased in peritoneal injury leading to SP/EPS, most of the MMP-2 in the dialysate drained from the peritoneal cavity was the latent form that was lacking activit...

Recently, matrix metalloproteinases (MMP), in particular the gelatinases MMP-2 and MMP-9, generally considered as tumor markers for clinical applications. A longitudinal 2-years follow-up survey was performed on dogs with cutaneous tumor. Serum samples were obtained from 22 dogs with different cutaneous tumors and 22 health dogs at the time of surgery and one month, three months and one year af...

Gingipains (RgpA, RgpB, and Kgp) are major virulence factors of the periodontitis-causing bacterium Porphyromonas gingivalis. Isolation gingipains from crude protein sample P. gingivalis is critical for studying underlying invasion mechanism that contributes to periodontitis, Alzheimer’s disease, cardiovascular disease (CVD). Chromatographic processes molecular cloning two standard techniques o...

Snake venom contains various bioactive proteins and peptides, of which enzymes make up a significant portion. Desert Black Cobra (Walterinnesia morgani) is venomous snake distributed mainly in the Middle East including southeastern Türkiye. The aim present study to investigate key enzyme activities protein profile W. morgani originating from Sanliurfa province. After determination content, samp...

Stroke is one of the leading causes death and disability worldwide. However, treatment options for ischemic stroke remain limited. Matrix-metalloproteinases (MMPs) contribute to brain damage during strokes by disrupting blood-brain barrier (BBB) causing edemas. Carnosine, an endogenous dipeptide, was found us others be protective against injury. In this study, we investigated whether carnosine ...

AIM To determine whether matrix metalloproteinase-9 (MMP-9) may be a useful adjunctive tool for predicting unfavorable biological behavior of papillary thyroid carcinoma (PTC) by evaluating the expression profile and proteolytic activity of MMP-9 in PTC by different techniques and correlating the findings with clinicopathological prognostic factors. METHODS Immunohistochemical localization of...

Avian bile is rich in matrix metalloproteinases (MMP), the enzymes that cleave extracellular matrix proteins such as collagens and proteoglycans. Changes in bile MMP expression have been correlated with hepatic and gall bladder pathologies, but the significance of their expression in normal, healthy bile is not understood. We hypothesized that the MMP in bile may aid the digestion of native col...

Objective(s):N-myc downstream regulated gene 2 (NDRG2) is a candidate gene for tumor suppression. The expression of NDRG2 is down-regulated in several tumors including lung cancer. The aim of this study was to explore the effect of NDRG2 overexpression on invasion, migration, and enzymatic activity of matrix metalloproteinase-2 (MMP-2) and -9 (MMP-9) in human lung adenocarcinoma A549 cells.  Ma...

To investigate the pathophysiological role of fibroblasts in tissue metabolism, we analysed gelatin-degrading enzymes secreted from skin cells in culture. Using a gelatin-zymography method, matrix metalloproteinase (MMP)-2 was constitutively secreted from fibroblasts, whereas both MMP-2 and MMP-9 were secreted from keratinocytes. MMP-9 expression by fibroblasts was induced by the addition of tr...
