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.
