sampling and separation of serum from blood cells. We agree with M. John and K. Jung that we must be aware of pre-analytical problems when analysing the circulating matrix metalloproteinase (MMP)-9 and tissue inhibitor of metalloproteinase (TIMP)-1 levels. However, we used only serum samples in our study because we usually use serum samples for clinical examinations in our hospital. Therefore, ...

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...

Background: Osteoarthritis (OA) is a progressive, age-associated disease that is characterized with cartilage destruction, subchondral bone remodeling and inflammation of the synovial membrane. Considering the complications of common treatments of OA, including non-steroidal anti-inflammatory drug (NSAIDs) and corticosteroids, investigating new treatments for this disorder is crucial. Recently,...

BACKGROUND Thermal injury is associated with several biochemical and histopathological alteration in tissue. Analysis of these objective parameters in research and clinical field are common to determine healing rate of burn wound. Negative pressure wound therapy has been achieved wide success in treating chronic wounds. This study determines superficial burn wound healing with intermittent n...

Purpose: In retinal endothelial cells, homocysteine (Hcy) activates matrix metalloproteinase (MMP)-9, which results in apoptosis. This study investigated these effects of Hcy human trabecular meshwork cells (HTMC).Methods: HTMC cultures using 5 mM low or 20 high glucose (HG)-containing media were exposed to 100 μM for 3 days. Cell viability was assessed with the MTT (3-[4, 5-dimethylthiazol-2-y...

Epidemiological and experimental studies suggest that diesel exhaust particles (DEPs) may be associated with increased respiratory mortality and morbidity. Several recent studies have also shown that DEPs increase the production of inflammatory cytokines by human bronchial epithelium (HBE) cells in vitro. The present study investigates the effects of DEPs on the interaction of l-HBE cells (16HB...

Nowadays, Stroke is regarded as the second major cause of death and third morbidity globally. The ischemic stroke (IS) among most fatal kind strokes. Thus, due to importance this subject, article aims analyze role fibrosis markers (matrix metalloproteinase-9, tissue inhibitor matrix metalloproteinases-1), cytokines (tumor necrosis factor-α, interferon-γ, monocytic chemoattractant protein-1) in ...

OBJECTIVE This study intends to verify the expression levels and correlation of aromatase, matrix metalloproteinase 2 (MMP-2), matrix metalloproteinase 9 (MMP-9) and CD44 in ductal carcinoma in situ (DCIS) and infiltrating ductal carcinoma (IDC) when both are found in the same breast. METHODS One hundred and ten cases were evaluated by tissue microarray (TMA) and immunohistochemically screene...
