Serum stimulates the production of prostaglandins by transformed mouse fibroblasts. Hydrocortisone (cortisol) inhibits this stimulation. The half-maximal inhibition occurs at 6x10-9 M. Studies with cells labeled with [3H]arachidonic acid in their lipids show that the stimulation by serum results in the release of arachidonic acid from the cellular lipids, mostly phospholipids. Hydrocrotisone in...
Lipid and lipid metabolite profiling are important parameters in understanding the pathogenesis of many diseases. Alkynylated polyunsaturated fatty acids are potentially useful probes for tracking the fate of fatty acid metabolites. The nonenzymatic and enzymatic oxidations of ω-alkynyl linoleic acid and ω-alkynyl arachidonic acid were compared to that of linoleic and arachidonic acid. There wa...

The 85-kDa cytosolic PLA2 (cPLA2) mediates agonist-induced arachidonic acid release in many cell models, including mouse peritoneal macrophages. cPLA2 is regulated by an increase in intracellular calcium, which binds to an amino-terminal C2 domain and induces its translocation to the nuclear envelope and endoplasmic reticulum. Phosphorylation of cPLA2 on S505 by mitogen-activated protein kinase...
