Elevated protease activities in human amnion and chorion correlate with preterm premature rupture of membranes.
Ainult registreeritud kasutajad saavad artikleid tõlkida

OBJECTIVE
The mechanism(s) of preterm premature rupture of fetal membranes resulting in preterm birth remains unknown. Studies suggest that fetal membranes are susceptible to weakening by protease attack and that collagenases may be active at the site of rupture. In this study fetal membranes from
Effect of NCO-700, an inhibitor of protease, on lysosomal rupture in the ischemic myocardium.

Logi sisse
The effect of NCO-700 (1), a protease inhibitor, on subcellular distribution of lysosomal enzymes was studied in the ischemic perfused rat heart. Ischemia was induced by lowering the afterload pressure of the working heart preparation. The subcellular distribution of lysosomal enzymes was estimated
Lysosomal rupture, necroapoptotic interactions and potential crosstalk between cysteine proteases in neurons shortly after focal ischemia.

Ischemic cell death is a complex process and the initial distinction between apoptosis and necrosis appears to be an oversimplification. We previously reported that in ischemic neurons with disrupted plasmalemma, apoptotic mechanisms were also active. In the present study, we investigated cellular
Systematic analysis of protease gene expression in the rhesus macaque ovulatory follicle: metalloproteinase involvement in follicle rupture.

Protease genes were identified that exhibited increased mRNA levels before and immediately after rupture of the naturally selected, dominant follicle of rhesus macaques at specific intervals after an ovulatory stimulus. Quantitative real-time PCR validation revealed increased mRNA levels for matrix
Loss of Protease-Activated Receptor 4 Prevents Inflammation Resolution and Predisposes the Heart to Cardiac Rupture after Myocardial Infarction

Background: Cardiac rupture is a major lethal complication of acute myocardial infarction (MI). Despite significant advances in reperfusion strategies, mortality from cardiac rupture remains high. Studies suggest that cardiac rupture can be accelerated by thrombolytic therapy, but the
Protease inhibitor 15, a candidate gene for abdominal aortic internal elastic lamina ruptures in the rat.

The inbred Brown Norway (BN) rat develops spontaneous ruptures of the internal elastic lamina (RIEL) of the abdominal aorta (AA) and iliac arteries. Prior studies with crosses of the BN/Orl RJ (susceptible) and LOU/M (resistant) showed the presence of a significant QTL on chromosome 5 and the
Neutrophil elastase and secretory leukocyte protease inhibitor in prelabor rupture of membranes, parturition and intra-amniotic infection.

OBJECTIVE
Neutrophil elastase (NE), a multifunctional serine protease stored in azurophilic granules of mature neutrophils, is capable of intracellular degradation of proteins during phagocytosis and extracellular degradation of connective tissue during an inflammatory process. Secretory leukocyte
Identification of proteases that regulate erythrocyte rupture by the malaria parasite Plasmodium falciparum.
Ainult registreeritud kasutajad saavad artikleid tõlkida
Logi sisse
Newly replicated Plasmodium falciparum parasites escape from host erythrocytes through a tightly regulated process that is mediated by multiple classes of proteolytic enzymes. However, the identification of specific proteases has been challenging. We describe here a forward chemical genetic screen
Collagenolytic protease expression in cranial cruciate ligament and stifle synovial fluid in dogs with cranial cruciate ligament rupture.

OBJECTIVE
To determine expression of collagenolytic genes and collagen degradation in stifle tissues of dogs with ruptured cranial cruciate ligament (CCL).
METHODS
Six dogs with CCL rupture and 11 dogs with intact CCL.
METHODS
Gene expression in CCL tissue and synovial fluid cells was studied using
Thermal stability and catalytic properties of protease from Bacillus sp. P45 active in organic solvents and ionic liquid.

The parameters half-life, z value, enthalpy, entropy, and free energy were evaluated in the temperature range of 40 to 55°C for a Bacillus sp. P45 protease present in a medium composed of ionic liquid (IL) and organic solvent. The protease was previously treated in IL [Emim][Tf2 N] and increased
Ultrastructural changes to the midgut of the black field cricket (Teleogryllus commodus) following ingestion of potato protease inhibitor II.

Ultrastructural changes to the midgut epithelium of nymphs of the black field cricket (Teleogryllus commodus) after ingestion of potato protease inhibitor II (PPI-II) (0.6% (w/v) in artificial diet) were determined by light and electron microscopy. Crickets fed diet containing PPI-II grew more

Senescence is a tightly regulated process and both compartmentalisation and regulated activation of degradative enzymes is critical to avoid premature cellular destruction. Proteolysis is a key process in senescent tissues, linked to disassembly of cellular contents and nutrient remobilisation.
Regulation of smooth muscle cell growth, function and death in vitro by activated mast cells--a potential mechanism for the weakening and rupture of atherosclerotic plaques.

The fibrous cap of a lipid-containing atherosclerotic plaque consists of collagen produced by arterial smooth muscle cells (SMCs) of synthetic phenotype. A thick cap protects the lipid-rich core, whereas a thin cap predisposes it to rupture, with ensuing acute clinical complications, such as
Ureaplasma infection-mediated release of matrix metalloproteinase-9 and PGP: a novel mechanism of preterm rupture of membranes and chorioamnionitis.

Premature rupture of membranes and preterm delivery are associated with Ureaplasma infection. We hypothesized that Ureaplasma induced extracellular collagen fragmentation results in production of the tripeptide PGP (proline-glycine-proline), a neutrophil chemoattractant. PGP release from collagen
Blocking effect of a biotinylated protease inhibitor on the egress of Plasmodium falciparum merozoites from infected red blood cells.

The malaria parasite Plasmodium falciparum invades human red blood cells. Before infecting new erythrocytes, the merozoites have to exit their host cell to get into the blood plasma. Knowledge about the mechanism of egress is scarce, but it is thought that proteases are basically involved in this
