Research Abstract

Lysophosphatdic acid (LPA) has recently been implicated in various fibrotic disease, including pulmonary fibrosis, renal fibrosis and peritoneal fibrosis. It is, however, not clear in which way LPA is produced and how LPA production is regulated in these fibrotic diseases. In this study, by studying expression of LPA-producing enzyme, autotaxin (ATX), and quantifying substrate of ATX using LC/MS, we found that LPA infibrotic diseases is regulated by up-regulation of both ATX and its substrate, lysophosphatidylcholine (LPC).
