To observe the changes of neutrophil gelatinase associated apolipoprotein (neutrophil lipocalin), lipoprotein phospholipase A2 and inflammatory cytokine hypersensitive C-reactive protein in patients with coronary heart disease to explore correlation between serum lipoproteinassociated A2, lipocalin, degree artery disease. 200 inpatients cardiovascular department our hospital were divided into g...

The objective of this research was to determine the presence virulence genes (asa1, gelE, cylA, ace, esp, hyl and efaA), vancomycin resistance (vanA, vanB, vanC2/C3) some antibiotics Enterococcus spp. isolates previously identified from different stages ripened white cheese production. In addition, gelatinase, β-hemolytic DNase activity, biofilm formations were examined phenotypically. study, e...

Analysis of inflammatory exudate collected from sites of experimental periodontitis in cynomolgus monkeys has revealed the presence of collagenase and a 92-kDa gelatinase that comigrated after electrophoresis with the 92-kDa gelatinase released from polymorphonuclear leukocytes. Since neutralizing antibodies to fibroblast collagenase had no effect on the collagenase activity and bacterial colla...

In this study, we investigated the expression of activated gelatinase A and membrane-type metalloproteinase (MT-MMP) induced by concanavalin A (ConA) in four highly invasive glioma cell lines (UWR2, UWR3, U251MG, and SNB-19). We also examined gelatinase A and MT-MMP expression in human brain tumor tissues in vivo. Gelatin zymography showed that all four cell lines expressed latent progelatinase...

Arginase 1 (ARG1) metabolizes arginine, thus reducing the availability of arginine as a substrate for nitric oxide synthase (NOS). The decreased production of nitric oxide (NO) by NOS and the production of ornithine by ARG1 affect immune responses and tissue regeneration at sites of infection, respectively. We here demonstrate that ARG1 is synthesized in myelocytes/metamyelocytes and is stored ...

Activated gelatinase A is reportedly associated with tumor spread. We identified novel matrix metalloproteinases that localize on the cell surface and mediate the activation of progelatinase A. Thus, these progelatinase A activators were named membrane-type matrix metalloproteinase-1 and -2 (MT-MMP-1 and -2, respectively). MT-MMP-1 is overexpressed in malignant tumor tissues, including lung and...
