In ovarian cancer, there are several tumor-associated antigen molecules found on the surface or inside the cells that can potentially serve as targets for immune recognition and response; these are, e.g., CA125, p53 protein, FRα, HER2, and cancer–testis antigens, like MAGE-A4 and NY-ESO-1 [117]. The gene discussed is FOLR1; the disease is ovarian cancer.
