High impact information on Ctsg_predicted


Biological context of Ctsg_predicted


Anatomical context of Ctsg_predicted

  • Susceptibility of soluble and matrix fibronectins to degradation by tissue proteinases, mast cell chymase and cathepsin G [9].
  • Effective concentrations for the combined cathepsin G and elastase in the incubation mixture were similar to the concentrations of these enzymes in PMN-conditioned medium that produced cytotoxicity to hepatocytes [10].
  • Neutrophil derived cathepsin G induces potentially thrombogenic changes in human endothelial cells: a scanning electron microscopy study in static and dynamic conditions [2].
  • In the same stimulated macrophages there was little activity against type I collagen (associated with MMP-13 [collagenase-3] on the basis of Western blotting), no activity suggestive of stromelysin or matrilysin, and no measurable secretion of the serine proteinases, elastase and cathepsin G [11].
  • Rat leukocytes from inflammatory peritoneal exudates respond in vitro to a variety of chemotactic and phagocytic stimuli by releasing both elastase and cathepsin G neutral proteinase enzyme activities [12].

Associations of Ctsg_predicted with chemical compounds

  • Leucocyte proteinases, e.g. leucocyte elastase and cathepsin G, are inhibited by heparin [13].
  • By contrast, the serine protease inhibitors, aprotinin and 4-(2-aminoethyl)-benzene-sulfonyl fluoride, were less effective in inhibiting cathepsin G and elastase activities as well as cytotoxicity caused by the purified proteases or PMN-conditioned medium [10].
  • The six half-cystine residues in the mouse mast cell protease are located in the same positions as in the rat mast cell proteases, cathepsin G, and the lymphocyte proteases, suggesting that they all have identical disulfide bond arrangements [14].
  • Previous studies showed a higher percentage of neutrophils from vitamin A deficient rats are hypersegmented and contain lower levels of cathepsin G than the neutrophils from control rats [15].
  • Collagenases and the serine proteinases elastase and cathepsin G in steroid-induced Pneumocystis carinii pneumonia [16].

Other interactions of Ctsg_predicted

  • The effect of THR, but not that of PAR1-AP, was significantly inhibited by hirulog(TM) (60 microg/mL), a specific and stochiometric THR inhibitor or by cathepsin-G (40 mU/mL), an inhibitor of PAR-1 [17].
  • Cytotoxicity of either purified enzyme or of conditioned medium could be prevented by plasma alpha-1-antitrypsin or soybean trypsin-chymotrypsin inhibitor, which were also potent inhibitors of enzymic activity of both cathepsin G and elastase [10].
  • Levels of myeloperoxidase, lysozyme, cathepsin G, alkaline phosphatase, gamma-glutamyltranspeptidase and N-acetyl-beta-glucosaminidase showed no sex-based differences [18].
