Disruption of 12/15-lipoxygenase expression in peritoneal macrophages. Enhanced utilization of the 5-lipoxygenase pathway and diminished oxidation of low density lipoprotein.
Previously, we isolated the murine "leukocyte-type" 12-lipoxygenase (L-12LO) cDNA from RNA of peritoneal-elicited cells that consisted predominantly of leukocytes (Chen, X.-S., Kurre, U., Jenkins, N. A., Copeland, N. G., and Funk, C. D. (1994) J. Biol. Chem. 269, 13979-13987). By in situ hybridization we show that the L-12LO gene is expressed abundantly in a subset of peritoneal macrophages but...
متن کاملEffect of Ganoderma Lucidum on Cytokine Release by Peritoneal Macrophages
Background: The water-soluble extract of Ganoderma lucidum (Reishi) has been used as an immunomodulator to stimulate spleen cells proliferation and cytokine expression. Objective: To investigate the effect of Ganoderma lucidum (G. lucidum) on cytokine production by mice peritoneal macrophages. Methods: Mice peritoneal macrophages were prepared by intra-peritoneal injection of 5 ml cold PBS. Per...
متن کاملEffect of Shark Liver Oil on Peritoneal Murine Macrophages in Responses to Killed-Candida albicans
Objective(s) Shark Liver Oil (SLO) is an immunomodulator. Macrophages play a key role in host defense against pathogens like fungi. Candida albicans have mechanisms to escape immune system. We determined the effect of killed-Candida on the in vitro viability of macrophages and the effect of SLO on augmentation of this potency. Materials and Methods Peritoneal macrophages were separated and c...
متن کاملRole of 12/15-lipoxygenase in the expression of MCP-1 in mouse macrophages.
Monocyte chemoattractant protein (MCP)-1 plays a key role in atherosclerosis and inflammation associated with visceral adiposity by inducing mononuclear cell migration. Evidence shows that mouse peritoneal macrophages (MPM) express a 12-lipoxygenase (12/15-LO) that has been clearly linked to accelerated atherosclerosis in mouse models and increased monocyte endothelial interactions in both rode...
متن کاملHypoxia increases LDL oxidation and expression of 15-lipoxygenase-2 in human macrophages.
OBJECTIVE Macrophage-mediated oxidation of low-density lipoprotein (LDL) by enzymes, such as the lipoxygenases, is considered of major importance for the formation of oxidized LDL during atherogenesis. Macrophages have been identified in hypoxic areas in atherosclerotic plaques. METHODS AND RESULTS To investigate the role of hypoxia in macrophage-mediated LDL oxidation, we incubated human mon...
