Arachidonic acid (AA) metabolizing enzymes and peroxisome proliferator-activated receptors (PPARs) have been shown to regulate the growth of epithelial cells. We have previously reported that exposure to the 5-lipoxygenase activating protein-directed inhibitor MK886 but not the cyclooxygenase inhibitor, indomethacin, reduced

We have investigated the effects of five peroxisome proliferators (PPs : clofibric acid, DEHP, WY14,643, nafenopin, and LY171883) on the abundances of a large number of proteins in the livers of treated mice at 5- and 35-day time points. LY171883

Intraperitoneal administration of zymosan to mice resulted in marked biosynthesis of eicosanoids and influx of neutrophils with distinct time course profiles. 6-Keto-prostaglandin-F1 alpha (6-KPA) increased between 30 and 60 min and rapidly decreased thereafter. Leukotriene (LT)C4 levels showed similar patterns
