Lymphangioleiomyomatosis (LAM) is characterised by lung cysts and airflow obstruction. Matrix metalloproteinases have been implicated in lung destruction in LAM. We performed a randomised, double-blind trial, comparing the matrix metalloproteinases inhibitor doxycycline with placebo on the progression of LAM. 23 females with LAM were randomised to doxycycline 100 mg daily for 3 months followed ...

BACKGROUND FoxM1 has been shown to play a critical role in the pathogenesis of various epithelial malignancies. However, its role in lymphoid malignancies has not been fully clarified. We, therefore, investigated the role of FoxM1 expression in a large cohort of diffuse large B-cell lymphoma samples and panel of cell lines. DESIGN AND METHODS FoxM1 expression was investigated in a large serie...

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 ...

The expansion of cysts in polycystic kidneys bears several similarities to the invasion of the extracellular matrix by benign tumors. We therefore hypothesized that cyst-lining epithelial cells produce extracellular matrix-degrading metalloproteinases and that the inhibition of these enzymes may represent a potential target for therapeutic intervention. Using in situ hybridization, we first ana...

In skeletal muscles, levels and activity of Matrix MetalloProteinases (MMPs) and Tissue Inhibitors of MetalloProteinases (TIMPs) have been involved in myoblast migration, fusion and various physiological and pathological remodeling situations including neuromuscular diseases. This has opened perspectives for the use of MMPs' overexpression to improve the efficiency of cell therapy in muscular d...

Inflammation plays a critical role in the development of cancer. Matrix Metalloproteinase (MMP) functions in the remodeling of the extracellular matrix that is integral for many normal and pathological processes such as morphogenesis, angiogenesis, tissue repair, and tumor invasion. The tissue inhibitor of metalloproteinases (TIMPs) family regulates the activity of multifunctional metalloprotei...

Metalloproteinases have been implicated as important factors mediating the tissue migration of a variety of normal and transformed cells. The conditioned medium (CM) of fetal human astrocytes and five glioma cell lines did not degrade azocoll in suspension, but several proteolytic activities, inhibitable by 1,10-phenanthroline, were detected on sodium dodecyl sulfate-polyacrylamide gels contain...

What makes an MMP an MMP? They all have a conserved zinc-binding site in their catalytic domain (HEXGHXXGXXH), and the sequence PRCGVPD in the propeptide domain. The cysteine residue serves to anchor the propeptide to the catalytic zinc, suppressing enzymatic activity in a manner that is not unlike a thumb in an open mouth. Release of this interaction results in proteolytic activity. MMPs are a...

objective: obesity increases production of the extracellular matrix (ecm) role in pathological cardiovascular damage. regular exercise and the use of medicinal plants, particularly celery, in damage to be effective. the aim of this study is to investigate the changes in matrix metalloproteinases 2,9 (mmp 2,9) and tissue inhibitor of matrix metalloproteinase 1 (timp-1) with synchronized exercise...
