摘要: Lysophosphatidic acid (LPA) is a ubiquitously present signalling molecule involved in diverse cellular processes such as cell migration, proliferation and differentiation. LPA acts an autocrine and/or paracrine via different G-protein-coupled receptors (LPARs) that trigger broad range of intracellular cascades, especially the RHOA pathway. Mounting evidence suggests crucial role LPA/LPAR-axis cancer metastasis promising studies are underway to investigate therapeutic potential LPAR-antagonists. This review summarises current knowledge on how promotes cytoskeletal remodelling enhance migratory invasive properties cells, which may ultimately contribute metastasis. Furthermore, we provide comprehensive transcriptome analyses published microarrays more than 350 normal tissues 1700 malignant define expression signatures LPARs LPA-generating enzymes autotaxin (ATX) lipase member 1 (LIPI). These demonstrate ATX highly expressed variety carcinomas sarcomas, whereas LIPI almost exclusively overexpressed aggressive Ewing's underscores contribution metastatic disease. In addition, these show entities display distinct distinguish them from one another. Finally, discuss approaches specifically target LPA/LPAR circuits experimental therapy.
