Melanoma cells break down LPA to establish local gradients that drive chemotactic dispersal. [PDF]
, 2014 The high mortality of melanoma is caused by rapid spread of cancer cells, which occurs unusually early in tumour evolution. Unlike most solid tumours, thickness rather than cytological markers or differentiation is the best guide to metastatic potential.

Lysophosphatidic acid receptors in cancer pathobiology.
Histology and histopathology, 2014 Lysophosphatidic acid (LPA) receptors (LPA₁ to LPA₆) are G protein-coupled transmembrane and mediate a variety of biological responses through the binding of LPA, such as cell proliferation, migration, morphogenesis and differentiation. Previously, high secretion levels of LPA were found in blood and ascites from patients with aggressive ovarian cancer.

The PDZ protein GIPC regulates trafficking of the LPA1 receptor from APPL signaling endosomes and attenuates the cell's response to LPA. [PDF]
PLoS ONE, 2012 Lysophosphatidic acid (LPA) mediates diverse cellular responses through the activation of at least six LPA receptors--LPA(1-6,) but the interacting proteins and signaling pathways that mediate the specificity of these receptors are largely unknown.

LPP3 mediates self-generation of chemotactic LPA gradients by melanoma cells [PDF]
, 2017 Melanoma cells steer out of tumours using self-generated lysophosphatidic acid (LPA) gradients. The cells break down LPA, which is present at high levels around the tumours, creating a dynamic gradient that is low in the tumour and high outside.

Lysophosphatidic acid receptor agonists and antagonists (WO2010051053) [PDF]
Expert Opinion on Therapeutic Patents, 2011 Lysophosphatidic acid (LPA) is a bioactive lipid involved in signaling pathways that result in cell survival, proliferation, migration and invasion. These cellular responses are a critical element of both normal development as well as pathophysiology.

Control of Intestinal Epithelial Permeability by Lysophosphatidic Acid Receptor 5 [PDF]
Cellular and Molecular Gastroenterology and Hepatology, 2021 Epithelial cells form a monolayer at mucosal surface that functions as a highly selective barrier. Lysophosphatidic acid (LPA) is a bioactive lipid that elicits a broad range of biological effects via cognate G protein-coupled receptors. LPA receptor 5 (LPA5) is highly expressed in intestinal epithelial cells, but its role in the intestine is not well ...

Endogenous lysophosphatidic acid (LPA1) receptor agonists demonstrate ligand bias between calcium and ERK signalling pathways in human lung fibroblasts [PDF]
, 2016 Background and Purpose Human lung fibroblasts (HLF) express high levels of the LPA1 receptor, a GPCR that responds to the endogenous lipid mediator, lysophosphatidic acid (LPA).

TRIP6 Enhances Lysophosphatidic Acid-induced Cell Migration by Interacting with the Lysophosphatidic Acid 2 Receptor [PDF]
Journal of Biological Chemistry, 2004 Lysophosphatidic acid (LPA) induces actin rearrangement, focal adhesion assembly, and cell migration through the activation of small G protein Rho and its downstream effectors. These diverse cellular responses are mediated by its associated G protein-coupled receptors.
