1-O-9Z-Octadecenoyl-sn-glyceryl-3-phosphoricacidsodiumsalt

Description

Lysophosphatidic acid (325465-93-8) is a multifunctional intercellular bioactive phospholipid.1?Stimulates the growth of a variety of cells including fibroblasts, vascular smooth muscle cells, endothelial cells and keratinocytes among others.1?Acts as a proliferative and anti-apoptotic factor.2?Lysophophatidic acid is an agonist at LPA1?(EDG-2), LPA2?(EDG-4) and LPA3?(EDG-7) receptors.3?LPA-primed astrocytes induce axonal outgrowth of cortical progenitors.4

The Uses of 1-O-9Z-Octadecenoyl-sn-glyceryl-3-phosphoricacidsodiumsalt

It is an 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. LPA has also been described to potentiate acetylchloine receptor currents by G-protein-mediated activation of Ca2+-dependent/independent protein kinase C.

What are the applications of Application

Lysophosphatidic Acid is a endogenous glycerophospholipid signaling ligand molecule and ligand activator for EDG-2, EDG-4, and EDG-7

in vitro

lpa could mediate signal transduction via edg/lpa receptor, inducing the proliferation, migration, adhesion and antiapoptotic function of tumor cells. additionally, lpa was found to elicit upregulation of vegf, leading to an indirect influence on initiation and progression of malignancies. lpa could also stimulate matrix metalloproteinase secretion and tumor angiogenesis factor [1].

in vivo

lpa was tested for its vascular remodeling effect in a rat model of hypoxic pulmonary hypertension. serum from animals in the hypoxic group showed higher chemoattractant properties toward rat primary lung fibroblasts, and such cell migration increase was prevented by the lpa receptor 1 and 3 antagonists. lpa also found to increase adhesive properties of human pulmonary artery endothelial cells, via the activation of lpa receptor 1 or 3 [1].
