General description

Lysophosphatidic acid (LPA) belongs to a class of phospholipids, which has a glycerol backbone attached through a phosphate group, an aliphatic chain and a hydroxyl group. The phosphate group is linked to the sn-3 position and the aliphatic chain is linked to either sn-1 or sn-2 position. The hydroxyl group is connected to the remaining sn-1 or sn-2 position.


18:1 Lyso PA or 1-oleoyl-2-hydroxy-sn-glycero-3-phosphate has been used: to study its effects on intracellular calcium concentration [Ca2+]i transient in pheochromocytoma cell 12 (PC12) cells and primary astrocytes. It has also been used to study its effects on blood glucose level and physical endurance in fasted mice.

Biochem/physiol Actions

Biological responses to LPA: Cell Proliferation, Inhibition of differentiation (neuroblastoma cells, myoblasts), Platelet aggregation, Smooth muscle contraction, Neurotransmitter release, Stress fibre formation/cell rounding/neurite retraction, Cell-surface-fibronectin binding, Tumor cell invasion, Chemotaxis (dictyostelium amoebae), Cl--mediated membrane depolarization (fibroblasts), Inhibition of connexin 43 based cell-cell communication, Increased tight junction permeability (brain endothelial cells). Note: The bioactivity of LPA appears to require long (i.e., C16 to C18) acyl carbon chains of the type usually found associated with membrane lipids although optimum requirements for a single type of acyl carbon chain are not universal. The bioactivity decreases with shorter chain length. In serum, oleoyl and palmitoyl fatty acid containing LPA are the predominant species.

The small molecule NSC676914A was previously identified as an NF-κB inhibitor in TPA-stimulated HEK293 cells (Mol Can Ther 8:571-581, 2009). We hypothesized that this effect would also be seen in ovarian cancer cells, and serve as its mechanism of cytotoxicity.

The glycerol phosphate pathway produces more than 90% of the liver triacylglycerol (TAG). LysoPA, an intermediate in this pathway, is produced by glycerol-3-phosphate acyltransferase. Glycerophosphodiester phosphodiesterase domain containing 3 (GDPD3), whose gene was recently cloned, contains lysophospholipase D activity, which
