Matrix metalloproteinase (MMP)-9 is involved in extracellular matrix degradation and leukocyte migration. To determine the role of MMP-9 in the innate immune response to peritonitis, MMP-9 gene-deficient (MMP-9(-/-)) and normal wild-type mice were i.p. infected with Escherichia coli. MMP-9 mRNA and pro-MMP-9 protein levels increased rapidly upon induction of peritonitis. Although MMP-9(-/-) neu...
Matrix metalloproteinase-9 (MMP-9) plays a central role in the progression of the cancer. While a large number of studies have contributed to our understanding of the molecular mechanisms responsible for upregulating MMP-9 gene expression in normal and cancer cells, our knowledge on the signals that suppress MMP-9 expression is much more limited. Here, we report that EGF and BMP-4 cooperate to ...
BACKGROUND In humans trophoblast invasion and vascular remodeling are critical to determine the fate of pregnancy. Since guinea-pigs share with women an extensive migration of the trophoblasts through the decidua and uterine arteries, and a haemomonochorial placenta, this species was used to evaluate the spatio-temporal expression of three enzymes that have been associated to trophoblast invasi...
Purpose: The aim of this study is to explore the effects gossypin on matrix metalloproteinases -2 (MMP-2) and MMP-9 genes in prostate cancer cells. Materials Methods: PC3 cells were grown culture treated with three different concentrations (25-50-100 µg/ml) cisplatin (50 µM) as a positive control. First, RNA isolation was performed. Then, cDNA synthesis performed RT-PCR used evaluate mRNA expre...
PURPOSE To investigate the expression and pivotal role of matrix metalloproteinase (MMP)-9 in the ex vivo expansion of human limbal explants with or without amniotic membrane (AM). METHODS Corneoscleral buttons were cultured on intact, denuded AM or plastic dishes for 3 weeks. To determine the role of MMP-9 in cell migration, either the MMP inhibitor GM6001 or an MMP-9 antibody was used. Expr...
The highly aggressive adult sarcomas are characterized by high levels of matrix metalloproteinase (MMP)-2 and -9, which play crucial roles in tumor invasion and metastasis by degradation of the extracellular membrane leading to cancer cell spread to distal organs. We examined the effect of cytokines, mitogens, inducers and inhibitors on MMP-2 and MMP-9 secretion in chondrosarcoma (SW-1353), fib...
Arterial hypertension (AH) is the most common age-associated disease among working population. Polyetiology of AH requires a more thorough definition and study its predictors aiming for understanding role external influences, as well detection genetic polymorphisms at early stages, in order to limit their implementation. The scientific reviews discuss important abnormal vascular remodeling path...
Matrix metalloproteinase (MMP)-9 and neutrophil gelatinase-associated lipocalin (NGAL) have gained attention as cancer biomarkers. The inactive zymogen form of MMP-9 (pro-MMP-9) also exists as a disulphide-linked heterodimer bound to NGAL in humans. Leukaemias represent a heterogeneous group of neoplasms, which vary in their clinical behavior and pathophysiology. In this review, we summarize th...
We investigated whether three relevant polymorphisms (C-1562T, microsatellite -90(CA)(14-24), and Q279R) in the MMP-9 gene, or MMP-9 haplotypes, are associated with migraine and affect MMP-9 and tissue inhibitor of MMPs (TIMP)-1 levels in patients with migraine. We studied 102 healthy women (controls) and 187 women with migraine (141 without aura - MWA, and 46 with aura - MA). Patients with MWA...
