Action and Signaling of Lysophosphatidylethanolamine in MDA-MB-231 Breast Cancer Cells

Previously, we reported that lysophosphatidylethanolamine (LPE), a lyso-type metabolite of phosphatidylethanolamine, can increase intracellular Ca2+ ([Ca2+]i) via type 1 lysophosphatidic acid (LPA) receptor (LPA1) and CD97, an adhesion G-protein-coupled receptor (GPCR), in MDA-MB-231 breast cancer c...

Furthermore, LPE signaling was suggested as like LPA1/CD97-Gi/o proteins-phospholipase C-IP3-Ca2+ increase in these cells. In the present study, we further investigated actions of LPE not only in the [Ca2+]i increasing effect but also in cell proliferation and migration in MDA-MB-231 breast cancer cells. We utilized chemically different LPEs and a specific inhibitor of LPA1, AM-095 in comparison with responses in SK-OV3 ovarian cancer cells. It was found that LPE-induced Ca2+ response in MDA-MB-231 cells was evoked in a different manner to that in SK-OV3 cells in terms of structural requirements. AM-095 inhibited LPE-induced Ca2+ response and cell proliferation in MDA-MB-231 cells, but not in SK-OV3 cells, supporting LPA1 involvement only in MDA-MB-231 cells. LPA had significant effects on cell proliferation and migration in MDA-MB-231 cells, whereas LPE had less or no significant effect. However, LPE modulations of MAPKs (ERK1/2, JNK and p38 MAPK) was not different to those by LPA in the cells. These data support the involvement of LPA1 in LPE-induced Ca2+ response and cell proliferation in breast MDA-MB-231 cells but unknown GPCRs (not LPA1) in LPE-induced responses in SK-OV3 cells. Furthermore, although LPE and LPA utilized LPA1, LPA utilized more signaling cascades than LPE, resulting in stronger responses by LPA in proliferation and migration than LPE in MDA-MB-231 cells.
