We have recently described a novel cyclic peptide inhibitor CTTHWGFTLC (CTT) for matrix metalloproteinases (MMP)-2 and MMP-9, also called type IV collagenases or gelatinases (E. Koivunen et al., NAT: BIOTECHNOL:, 17: 768-774, 1999). As indicated by its amino acid composition, CTT is hydrophobic, and its partitioning into phospholipid films could be verified by the monolayer technique. Augmented...
Nanoscale drug carriers have been extensively developed to improve drug therapeutic efficiency. However, delivery of chemotherapeutic agents to tumor tissues and cells has not been favorably managed. In this study, we developed a novel "intelligent" nanoparticle, consisting of a gelatinase-cleavage peptide with poly(ethylene glycol) (PEG) and poly(ɛ-caprolactone) (PCL)-based structure for tumor...
To analyze the expression of soluble urokinase-type plasminogen activator receptor (suPAR) in plasma, and to explore value plasma suPAR, urinary neutrophil gelatinase associated lipid carrier protein (NGAL) kidney injury molecule-1 (KIM-1) early diagnosis adult with cardiac surgery-associated acute (CSA-AKI).
background: delayed graft function is a main complication after deceased donor kidney transplantation that adversely affects graft outcome. difficulties in prediction and early detection of delayed graft function have hindered the ability to perform proper therapeutic interventions. we investigated whether measuring urinary interleukin 18 and neutrophil gelatinase-associated lipocalin as marker...
A Mr 92,000 metalloprotease, originally observed in neutrophils, has been found to be secreted by various normal and malignant cells of fibroblastic, hematopoietic, and epithelial origin. The responsiveness of the various cell types to the tumor promoter phorbol ester (phorbol myristate acetate) to secrete this enzyme and a corresponding Mr 72,000 gelatinase has been determined using gelatin zy...
Cashew nut shell liquid (CNSL) has been used in traditional medicine for the treatment of a wide variety of pathophysiological conditions. To further define the mechanism of CNSL action, we investigated the effect of cashew nut shell extract (CNSE) on two matrix metalloproteinases, MMP-2/gelatinase A and MMP-9/gelatinase B, which are known to have critical roles in several disease states. We ob...
BACKGROUND AND PURPOSE Subarachnoid hemorrhage from intracranial aneurysm rupture produces a severe form of stroke. Extracellular matrix remodeling is associated with cerebral aneurysms and may play a role in the formation or rupture of these lesions. We previously reported a 3-fold increase in a 72-kDa serum gelatinase in a subgroup of aneurysm patients. The purpose of the present study was to...
The matrix metalloproteinases play an important role in matrix degradation, but there is limited information about this family of enzymes in either normal or diseased human liver. In this study, we have examined the synthesis of a 72 kDa type IV collagenase/gelatinase by human hepatic lipocytes in primary culture. Hepatic lipocytes were isolated from wedges of normal human donor liver by Pronas...
We have investigated the role of proteinases in the developmental program of bone, cartilage, tongue muscle and epithelial differentiation and remodeling in the mandibular arch during murine embryogenesis. Expression of matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) was tissue-specific with little or no expression in the epithelium of tooth buds, tongue or oral cavity. Gel...
Matrix metalloproteinase (MMP)-2 and -9 (gelatinases) participate in extracellular protein remodeling. Moreover, they are involved in the development of hepatic fibrosis. The goal of this study was to evaluate liver gelatinase activities after erythropoietin (Epo) treatment (1U/dose, sc) in experimentally damaged livers of rats treated with D-galactosamine (Gal, 800 mg/kg/dose, ip). Sixty rats ...
