OBJECTIVE
Increased local production of matrix metalloproteinases (MMPs) is a potential mechanism underlying structural protein degradation in abdominal aortic aneurysms (AAA). With an elastase-induced rodent model of AAA, we determined whether pharmacologic treatment with an MMP-inhibiting
Matrix metalloproteinases have increasingly been shown to be associated with diseases involving neovascularization and/or abnormal cellular migration or proliferation. A number of diseases of this type affect the retina. In this study, the activity of gelatinase A (MMP-2), the most abundant matrix
Gelatinases are a subgroup of the family of matrix metalloproteinases, which contains two members-gelatinase A and B. These enzymes play an important role in basement membrane homeostasis. Previous studies have associated basement membrane degradation with skeletal muscle atrophy. However, the
The degree of interstitial fibrosis and tubular atrophy (IFTA) is one of the strongest prognostic factors in glomerulonephritis (GN). In experimental models, high serum uric acid (UA) could contribute to IFTA through direct effects on the renal tubules, but the significance of this process has not
METHODS
In vitro-formed bovine nucleus pulposus (NP) tissues were used as a model for tumor necrosis factor-alpha (TNF-alpha) induced NP degeneration.
OBJECTIVE
To elucidate the signal transduction mechanisms regulating TNF-alpha induced matrix metalloproteinase (MMP) activity.
BACKGROUND
TNF-alpha
BACKGROUND
The role of urinary biomarkers of kidney injury in the prediction of adverse clinical outcomes in drug-induced chronic tubulointerstitial nephritis (D-CTIN) has not been well described.
METHODS
A total of 36 patients with D-CTIN were enrolled in the study. The baseline urinary excretion
Drusen are abnormal extracellular matrix deposits characteristic of age-related macular degeneration (AMD), a leading cause of blindness in the aging human population. The mechanisms underlying drusen formation are not well characterized. The purpose of this study was to examine the expression of
Serum neutrophil gelatinase-associated lipocalin (NGAL) is a low molecular weight protein released from activated neutrophils and intestine epithelium whose mRNA expression is increased in inflamed intestinal tissue. The purpose of this study was to explore the relationship between serum NGAL level
OBJECTIVE
Synovial fluid basic calcium phosphate (BCP) crystals are associated with severe joint degeneration accompanied by synovial hypertrophy. The metalloprotease 92 kDa gelatinase (MMP-9) has been implicated in the degradation of extracellular matrix in osteoarthritis, but the ability of BCP
Chicken embryo fibroblasts secrete a 72 kDa progelatinase that displays all of the characteristics of a matrix metalloproteinase. Employing reverse-transcription PCR and degenerate oligonucleotide primers that are specific for two highly conserved sequences found in all matrix metalloproteinases, a
Chronic constriction injury (CCI) to peripheral nerve causes a painful neuropathy in association with a process of axonal degeneration and endoneural remodeling that involves macrophage recruitment and local increase in extracellular proteases and tumor necrosis factor alpha (TNF-alpha). Cell
The matrix metalloproteinases (MMPs) are a family of proteases capable of degrading various components of the extracellular matrix (ECM). Among them, the membrane type MMP-1 (MT1-MMP) has been shown to participate in the activation of MMP gelatinase A (GelA), suggesting that they may function
Traditional kidney biomarkers are insensitive indicators of acute kidney injury, with meaningful changes occurring late in the course of injury. The aim of this work was to demonstrate the diagnostic potential of urinary osteopontin (OPN) and neutrophil gelatinase-associated lipocalin (NGAL) for
OBJECTIVE
Neutrophil gelatinase-associated lipocalin (NGAL) is a novel marker for early detection of renotubular deterioration. Despite the limited data concerning the NGAL in heart failure (HF), significance of NGAL in right-sided HF remains unknown. We assessed serum and urinary NGAL in left and
BACKGROUND
Patients with pre-existing impaired renal function are prone to develop acute contrast media induced nephropathy (CIN). Neutrophil gelatinase-associated lipocalin (NGAL), a new biomarker predictive for acute kidney injury (AKI), has been shown to be useful for earlier diagnosis of CIN;
