Subcellular localizations of CoA-independent transacylase and phospholipase D enzymes have been investigated in human neutrophils performing a two-step gradient system to separate plasma membranes from internal membranes and from the bulk of granules

In the human neutrophil, the fMLP-activated phospholipase D (PLD) was entirely calcium and tyrosine kinase dependent, but protein kinase C independent. An opposite regulation was observed with phorbol ester PMA, since the phospholipase D activity was

Phosphatidylcholine synthesis and degradation are tightly regulated to assure a constant amount of the phospholipid in cellular membranes. The chemotactic peptide fMLP and the phorbol ester, phorbol 12-myristate 13-acetate, are known to stimulate pho

Addition of oleic acid to Krebs-II cells stimulated by 9-fold [3H]choline incorporation into choline glycerophospholipids without affecting the selective incorporation of the precursor into diacyl subclass (90% of total [3H]choline glycerophospholipi

Short time effect of oleate and 1-O-alkyl-2-O-methyl-rac-glycero-3-phosphocholine (AMGPC) on choline incorporation into phosphatidylcholines were studied in HL-60 cells. The non lytic concentration of 50 microM oleate induced a three-fold increase in

Platelet-activating factor is a proinflammatory lipid active at subnanomolar concentrations. The intermembrane transfer of a biologically active PAF analog has been previously demonstrated in macrophages. Here we demonstrate that the specific activit

By searching into Expressed Sequence Tags databases (dbEST) using Blast X algorithm software and a plant phospholipase D as template, we have identified a cDNA from human brain (Z45777) which encodes for a protein similar to the amino acid region 743

The fMLP-activated phospholipase D (fMLP-PLD) was distinguished from the PMA-PLD on their relative sensitivity to calcium chelation and tyrosine kinase inhibitor. The receptor-mediated activity was abolished by calcium deprivation and genistein treat

Addition of oleic acid to Krebs II cells induced a rapid incorporation of [3H]choline into phosphatidylcholine, since 500 microM of the fatty acid stimulated choline incorporation by 5-fold over the control after 5 min of incubation. In fact, a notic

Plasma membranes have been isolated from the human epidermoid carcinoma cell line A431 by a rapid fractionation of lysate on Percoll density gradient at pH 9.6. Endoplasmic reticulum, lysosomes and mitochondria sedimented at the bottom of gradient wh
