1. In vitro characterization of jellyfish venom fibrin(ogen)olytic enzymes from Nemopilema nomurai
Abstract Background: Because jellyfish are capable of provoking envenomation in humans, they are considered hazardous organisms. Although the effects of their toxins are a matter of concern, information on the venom components, biological activity and pathological mechanisms are still scarce. Therefore, the aim of the present study was to investigate a seri

2. Neutrophil elastase ameliorates matrix metalloproteinase-9 to promote lipopolysaccharide-induced acute lung injury in mice 1
ABSTRACT PURPOSE: To investigate the regulatory roles of neutrophil elastase (NE) and matrix metalloproteinase-9 (MMP-9) in lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. METHODS: To construct LPS-induced ALI mouse models, wild-type C57BL/6 mice were administered 5.0 mg/kg of LPS through endotracheal, and/or 1.0 mg/kg of ONO-5046, and/

3. Componentes da matriz extracelular e seus reguladores no músculo liso brônquico na asma / Extracellular matrix components and regulators in the airway smooth muscle in asthma
There is an intimate relationship between the extracellular matrix (ECM) and smooth muscle cells within the airways. Few studies have comprehensively assessed the composition of different ECM components and its regulators within the airway smooth muscle (ASM) in asthma. With the aid of image analysis, the fractional area of total collagen and elastic fibres

4. Propriedades bioquímicas e cinético-enzimáticas de cisteíno- proteases do intestino médio da lagarta da soja / Biochemistry and kinectics-enzymatics properties of cysteine-proteases of the velvetbean caterpillar midgut
Protease inhibitors that react with insect specific proteases are candidates to have their genetic code inserted in genetically modified plants. The first step to achieve this is the characterization of proteolytic enzymes of these insects intestines. Cysteine-protease of the soluble and insoluble fractions from the midgut of Anticarsia gemmatalis were chara

5. Characterization of extracellular proteases produced by Xylella fastidiosa from citrus and grapevines. / Caracterização de proteases extracelulares produzidas por Xylella fastidiosa de citros e videira.
Xylella fastidiosa is a pathogenic bacterium found in several plants. These bacteria secrete extracellular proteases into the culture broth as visualized in sodium-dodecyl-sulfate polyacrylamide activity gels containing gelatin as a co-polymerized substrate. Three major protein bands were produced by strain X0 (citrus) with molar masses (MM) of 122, 84 and 6

6. Structural studies of DM43: a snake venom metalloprotease inhibitor extracted from Didelphis marsupialis opossum serum. / Estudos estruturais de DM43: Um inibidor de metaloprotease de veneno de serpente extraído do soro do gambá Didelphis marsupialis.
The natural resistance of the opossum, Didelphis marsupialis, towards snake venom is due to antibothropic factors present in the blood serum, of which DM43 is one. It is responsible for the inhibition of the hemorrhagic activity of the venom. With a view to better understanding the mechanism of action of this protein against venom metalloproteases, one of th

7. Distinct Mechanisms of Receptor and Nonreceptor Tyrosine Kinase Activation by Reactive Oxygen Species in Vascular Smooth Muscle Cells: Role of Metalloprotease and Protein Kinase C-δ
Reactive oxygen species (ROS) are implicated in cardiovascular diseases. ROS, such as H2O2, act as second messengers to activate diverse signaling pathways. Although H2O2 activates several tyrosine kinases, including the epidermal growth factor (EGF) receptor, JAK2, and PYK2, in vascular smooth muscle cells (VSMCs), the intracellular mechanism by which ROS a

8. Tumor necrosis factor α-converting enzyme mediates MUC5AC mucin expression in cultured human airway epithelial cells
Ectodomain shedding of epidermal growth factor receptor (EGFR) ligands [e.g., transforming growth factor type α (TGF-α)] and EGFR phosphorylation are implicated in mucin production in airway epithelial cells. Tumor necrosis factor α-converting enzyme (TACE) is reported to cleave precursor of TGF-α, with release of soluble mature TGF-α in various epithel

9. Cloning of genes encoding extracellular metalloproteases from Erwinia chrysanthemi EC16.
A 14-kilobase BamHI-EcoRI DNA fragment cloned from Erwinia chrysanthemi EC16 contained a gene encoding a metalloprotease inhibitor as well as three tandem prt genes encoding metalloproteases. The prt genes were separated from the inhibitor gene by a ca. 4-kilobase region that was necessary for extracellular secretion of the proteases. When individually subcl

10. Phosphoramidon blocks the pressor activity of porcine big endothelin-1-(1-39) in vivo and conversion of big endothelin-1-(1-39) to endothelin-1-(1-21) in vitro.
In porcine aortic endothelial cells, the 21-amino acid peptide endothelin-1 (ET-1) is formed from a 39-amino acid intermediate called "big endothelin-1" (big ET-1) by a putative ET-converting enzyme (ECE) that cleaves the 39-mer at the bond between Trp-21 and Val-22. Since big ET-1 has only 1/100-1/150th the contractile activity of ET-1, inhibition of ECE sh

11. Reversal of experimental autoimmune encephalomyelitis with a hydroxamate inhibitor of matrix metalloproteases.
Gelatinases, belonging to the matrix metalloproteases, contribute to tissue destruction in inflammatory demyelinating disorders of the central nervous system such as multiple sclerosis. We used experimental autoimmune encephalomyelitis (EAE) as an animal model to evaluate the effect of a hydroxamate matrix metalloprotease inhibitor (GM 6001) on inflammatory

12. TACE cleavage of proamphiregulin regulates GPCR-induced proliferation and motility of cancer cells
Communication between G protein-coupled receptor (GPCR) and epidermal growth factor receptor (EGFR) signalling systems involves cell surface proteolysis of EGF-like precursors. The underlying mechanisms of EGFR signal transactivation pathways, however, are largely unknown. We demonstrate that in squamous cell carcinoma cells, stimulation with the GPCR agonis
