Description

General description

Lysophosphatidic acid (LPA) is an essential metabolite for membrane biosynthesis. LPA interacts with the G protein-coupled receptors (GPCRs), called the LPA receptor and mediates signaling. Oleoyl-L-α-lysophosphatidic acid activates the receptor LPA4. In keratinocytes, oleoyl-L-α-lysophosphatidic acid promotes growth to some extent.

Application

Oleoyl-L-α-lysophosphatidic acid sodium salt has been used:

• for the activation of Ras homolog gene family, member A (RhoA) and expression of claudin-1 in human breast cancer epithelial cell line
• in RH7777 cells for cyclic adenosine monophosphate (cAMP) accumulation assay and calcium mobilisation assay
• in vitro luciferase assay and live-cell imaging

Biochem/physiol Actions

Endogenous agonist for LPA₁ and LPA₂ receptors. LPA does not induce angiogenesis, but has effects on endothelial cell physiology that are similar to those of sphingosine 1-phosphate. Induces cell migration of cancer and non-cancer cells.
