Abstract

Lysophosphatidic acid (LPA) receptors including LPA1, LPA2, and LPA3 mediate lysophosphatidic acid signals. We analyzed the expression of LPA receptors, vascular endothelial growth factor (VEGF), and interleukin-8 in 97 patients from normal ovary to ovarian cancer, using reverse transcription polymerase chain reaction. LPA2, LPA3, and VEGF expression ratios significantly increased in cancer, compared to those in non-cancerous state (P < 0.05). A significant correlation in the expression ratios between LPA2 or LPA3 and VEGF was found (γ = 0.617, P < 0.0001; γ = 0.431, P < 0.001) in patients with cancer. These results suggested that LPA2 and LPA3 may be involved in VEGF expression mediated by LPA signals in human ovarian oncogenesis.
