LPA and S1P are present in biological fluids and activate cells through stimulation of their respective G-protein-coupled receptors, LPA(1-3) and S1P(1-5). LPA stimulates fibroblast division and is important in wound repair. It is also active in maintaining the growth of ovarian cancers. S1P stimulates chemotaxis, proliferation and differentiation of vascular endothelial and smooth muscle cells and is an important participant in the angiogenic response and neovessel maturation. PA and C1P are believed to act primarily inside the cell where they facilitate vesicle transport. The lipid phosphates are substrates for a family of lipid phosphate phosphatases (LPPs) that dramatically alter the signaling balance between the phosphate esters and their dephosphorylated products. In the case of PA, S1P and C1P, the products are diacylglycerol (DAG), sphingosine and ceramide, respectively. These latter lipids are also bioactive and, thus, the LPPs change signals that the cell receives. The LPPs are integral membrane proteins that act both inside and outside the cell. The "ecto-activity" of the LPPs regulates the circulating and locally effective concentrations of LPA and S1P. Conversely, the internal activity controls the relative accumulation of PA or C1P in response to stimulation by various agonists thereby affecting cell signaling downstream of EDG and other receptors. This article will review the various LPPs and discuss how these enzymes could regulate signal transduction by lipid mediators."xsd:string |
