Background: Matrix MetalloProteinases (MMPs) degrade extracellular matrix components to provide normal remodeling and contribute to pathological tissue destruction and cell migration in endometriosis. It is accepted that MMPs are resistant to suppression by progesterone in endometriotic tissues. The physiological effects of progesterone are mediated by its two progesterone receptor (PR) isoform...

Cardiovascular complications are the leading cause of increasing and premature mortality in diabetic patients. Matrix metalloproteinases (MMPs) play an important role in the development and progression of vascular lesions. Matrix metalloproteinases are members of endopeptidases and are capable of degrading many extracellular matrix components. Results of recent studies indicated that non-pharma...

BACKGROUND AND OBJECTIVE Matrix metalloproteinases (MMP) and their inhibitors, tissue inhibitors of metalloproteinases (TIMP), regulate homeostasis and turnover of the extra cellular matrix. The aim of this study was to investigate the associations of serum MMP-9 and TIMP-1 with lung function. METHODS Spirometry was performed in a population-based sample of 888 subjects aged 70 years. Serum M...

Matrix metalloproteinases (MMPs) are involved in the regulation of the extracellular matrix (ECM) of the myocardium and thus the pathogenesis of vascular and cardiac hypertrophy. In this study, we investigated contribution of plasma matrix metalloproteinases to development of left ventricular hypertrophy (LVH) and diastolic dysfunction in hypertensive subjects. Hypertensive patients with (n = 2...

BACKGROUND Uncontrolled and increased extracellular matrix degradation during early anastomotic repair in the intestine may reduce wound strength increasing the risk of anastomotic dehiscence. AIMS To characterise the metalloproteinases present in intact and anastomosed ileum and colon to study their role in matrix degradation after surgery. SUBJECTS Tissue extracts of uninjured, and of ana...

BACKGROUND Remodeling of the injured vascular wall is dependent on the action of several extracellular proteases. Previous studies have shown that expression of matrix metalloproteinases (MMP-2 and MMP-9) is upregulated after vascular injury and that MMP-2 is required for the migration of cultured vascular smooth muscle cells across complex extracellular matrix barriers. The present study exami...

Matrix metalloproteinases (MMPs) are evolutionarily conserved and multifunctional effector molecules playing pivotal roles in development and homeostasis. In this study we explored the involvement of the five Arabidopsis thaliana At-MMPs in plant defence against microbial pathogens. Expression of At2-MMP was most responsive to inoculation with fungi and a bacterial pathogen followed by At3-MMP ...

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 ...

Polymorphonuclear neutrophils (PMNs) are the first line of defense against invading organisms in humans; in addition, PMNs contribute to the linking of innate and adaptive immunity. To fulfill their biological behavior, PMNs utilize an arsenal of proteolytic enzymes, including members of the matrix metalloproteinase family of zinc-dependent endopeptidases. PMNs express high levels of MT6-MMP (M...
