To investigate the expressions of lysophosphatidic acid (LPA) receptors at both mRNA and protein levels and their biological significance in different human ovarian cancer cell lines.
Reverse transcription-polymerase chain reaction (RT-PCR), streptovidin peroxidase-conjugated (SP) immunohistochemical assay and Western blotting were employed to measure the expression levels of LPA(1), LPA(2) and LPA(3) mRNA and LPA(2) and LPA(3) protein in cultured human ovarian cancer cell lines 3AO.SKOV3, and OVCAR3.
All the ovarian cancer cell lines expressed LPA(1), LPA(2) and LPA(3) mRNAs and LPA(2) and LPA(3) proteins.
LPA(1), LPA(2) and LPA(3) expressions occur extensively in human epithelial ovarian cancer cell lines, and LPA(2) and LPA(3) may be involved in the development and progression of human ovarian cancer.
