To study the role of PON2 in ovarian cancer, ID8-cells were transfected with either a pcDNA 3.1 vector carrying a human PON2 cDNA (hPON2) or pcDNA 3.1 vector alone and stable cell lines (ID8hPON2 and ID8EV, respectively) were established and stable mouse ovarian cancer cell lines were generated using G418 as a selective marker. This evidence concerns the gene PON2 and ovarian carcinoma.
