Abstract

Lysophosphatidic acid (LPA) signaling via G protein-coupled transmembrane LPA receptors (LPA1 to LPA6) mediates a variety of cellular functions, including cell proliferation, migration, morphogenesis, and differentiation. Recently, we demonstrated that the different induction of LPA receptors by estrogens regulates cell motile activity of rat liver epithelial WB-F344 cells. In the present study, to assess whether endocrine disruptors (EDs) are involved in cellular functions through LPA signaling, we measured cell motile activity and LPA receptor expressions in WB-F344 cells treated with bisphenol A (BPA) and 4-nonylphenol (4-NP). Using quantitative real time RT-PCR analysis, the Lpar1 expression was elevated in BPA-treated cells, whereas the Lpar3 expression was decreased. In contrast, 4-NP increased the Lpar3 expression, but not the Lpar1 and Lpar2. For cell motility assay with a Cell Culture Insert, cell motile activity of BPA-treated cells was significantly lower than that of untreated cells. In contrast, 4-NP markedly enhanced cell motile activity. The effects of BPA and 4-NP on cell motility were inhibited by the Lpar1 or Lpar3 knockdown. These results suggest that BPA and 4-NP may regulate cell motile activity through the different induction of LPA receptors in WB-F344 cells.
