General description

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.
Lysophosphatidic acid (1- or 2-acyl-lysophosphatidic acid/LPA), a bioactive phospholipid is seen at a low level in plasma (~100 nM). It is usually formed during the synthesis of phospholipid of cell membranes. It is produced by various cells like, activated platelets, epithelial cells, leukocytes, neuronal cells and tumor cells.


18:1 Lyso PA is suitable:
  • for liposome preparations
  • to study its apoptotic effect in HeLa cells
  • to determine the extraction recovery of LPA at neutral pH and acidic pH by chromatography
  • to use as a LPA agonist supplement in oocytes maturation medium to study its effects during in vitro maturation of bovine cumulus–oocyte complexes

Biochem/physiol Actions

Lysophosphatidic acid (1- or 2-acyl-lysophosphatidic acid/LPA) modulates cell motility, proliferation, invasion, survival and production of growth factors via G protein-coupled receptor (GPCR). 1-oleoyl-lysophosphatidic acid (LPA) has the ability to stimulate tyrosine phosphorylation of numerous substrates in Swiss 3T3 cells. It also helps to release calcium from the platelet subcellular fraction.

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.
