We measured the expression of mRNA levels of 21 TAAs, namely BIRC5, CA125, CEA, DDX43, EPCAM, FOLR1, Her-2/neu, MAGE-A1, MAGE-A2, MAGE-A3, MAGE-A4, MAGE-A6, MAGE-A10, MAGE-A12, MUC-1, NY-ESO-1, PRAME, p53, TPBG, TRT and WT1, on isolated serous epithelial ovarian cancer cells and compared the obtained data to the expression profiles of 4 estabilished ovarian cancer cell lines, OV-90, SKOV-3 OVCAR-3 and CAOV-3. The gene discussed is MAGEA3; the disease is ovarian carcinoma.
