We also examined the epithelial phenotypes of the Dicer-Pten DKO fallopian tube tumor-derived cancer cell lines (FTdT172 and FTdT967) together with two mouse cancer cell lines originated from the ovarian surface epithelium, OVdT4306 and OVdT4088, which were derived from K-rasG12D/+Pten−/− and K-rasG12D/+TP53−/− mice, respectively, [9]. This evidence concerns the gene DICER1 and cancer.
