Lysophosphatidic acid (LPA) 18:1 transcriptional regulation of primary human gingival fibroblasts.

ABSTRACT: The pleiotropic, bioactive lipid lysophosphatidic acid [(LPA), 1-acyl-sn-glycerol-3-phosphate] exerts critical regulatory actions in physiology and pathophysiology in many systems. It is present in normal bodily fluids, and is elevated in pathology (1). In vivo, "LPA" exists as distinct molecular species, each having a single fatty acid of varying chain length and degree of unsaturation covalently attached to the glycerol backbone via an acyl, alkyl, or alkenyl link. These species differ in affinities for the individual LPA receptors [(LPARs), LPA1-6] and coupling to G proteins (2). However, LPA 18:1 has been and continues to be the most commonly utilized species in reported studies. The actions of "LPA" remain poorly defined in oral biology and pathophysiology.
