(Submitter supplied) The cell of origin of serious ovarian cancer is unknown. To create a mouse model for this lethal cancer and identify early cancer biomarkers, we conditionally deleted both Dicer (essential for microRNA biosynthesis) and Pten (a negative regulator of the PI3K pathway) in the female reproductive tract. Beginning at ~3-5 months, these Dicer/Pten mutant mice develop high-grade serious carcinomas that initiate in the stroma of the fallopian tube through a mesenchymal-to-epithelial transition (MET), subsequently envelop the ovary, and then metastasize throughout the peritoneum, resulting in ascites and 100% lethality by 13 months. more...

(Submitter supplied) miR-34c inhibits Dicer/Pten double knockout mouse serous epithelial cancer cell proliferation by inducing cell cycle arrest and apoptosis. We found that miR-34c had a more dramatic effect on inhibiting tumor cell viability than let-7b. The action of miR-34c induced tumor cell cycle arrest in G1 phase and apoptosis and was accompanied with the regulation of key genes involved in cell proliferation and cell cycle G1/S transition. more...

(Submitter supplied) Our study presents the first genetic models of de novo high-grade serous carcinomas (HGSC) that originate in fallopian tube secretory epithelial cells and recapitulate the key genetic alterations and precursor lesions characteristic of human invasive ovarian cancer. Genomic copy number analysis, using array CGH, was performed on murine tumors in order to compare the overlap of copy number alterations between HGSC models and TCGA data.

(Submitter supplied) We engineered mice to have Ovgp1 promotor-driven expression of a tamoxifen-inducible Cre recombinase (iCre-ERT2), which inactivated the function of combinations of engineered floxed alleles of combinations of tumor suppressor genes in mouse oviducts (Fallopian tube) when mice were treated with tamoxifen. 21 samples were from oviductal tumors from mice with combinations of floxed alleles of Brca1, Trp53, Rb1, and/or Nf1 (BPRN mice), of which we analyzed 19. more...

(Submitter supplied) We treated 6-8 week old mice that had floxed alleles of both Apc and Pten (for both alleles in each case) that also carry an Ovgp1-iCre-ERT2 transgene, with one of two treatments; a third group received neither treatment. The Ovgp1-iCre-ERT2 expresses Cre recombinase fused to a tamoxifen-inducible fragment of the estrogen receptor, in tissues where the Ovgp1 gene (oviductal glycoprotein 1) is expressed, which is almost exclusively in mouse oviductal epithelium (equivalent to human fallopian tube epithelium = FTE). more...

(Submitter supplied) The inter-differentiation between cell states promotes cancer cell survival under stress and fosters non-genetic heterogeneity (NGH). NGH is, therefore, a surrogate of tumor resilience but its quantification is confounded by genetic heterogeneity. Here we show that NGH can be accurately measured when informed by the molecular signatures of the normal cells of origin. We surveyed the transcriptomes of ~ 4000 normal fallopian tube epithelial (FTE) cells, the cells of origin of serous ovarian cancer (SOC), and identified six FTE subtypes. more...

(Submitter supplied) Ovarian cancer is the fifth leading cause of cancer death among US women. Evidence supports the hypothesis that high-grade serous ovarian cancers (HGSC) may originate in the distal end of the fallopian tube. Although a heterogeneous disease, 96% of HGSC contain mutations in p53. In addition, the “p53 signature”, or overexpression of p53 protein (usually associated with mutation), is a potential precursor lesion of fallopian tube derived HGSC suggesting an essential role for p53 mutation in early serous tumorigenesis. more...

(Submitter supplied) In this study we generated a mouse model of high-grade serous ovarian carcinoma by targeting tumor suppressor genes Brca1, P53 and Pten using CRISPR/Cas9. The addition of Lkb1 to this combination reduced tumor latency and changed the origin of the tumor from the fallopain tube to the ovarian surface epithelium. Tumors originating the ovarian surface had distinct copy number alterations, highlighting the impact of the cell-of-origin on susceptibility and tumor development. more...

(Submitter supplied) Critical developmental “master transcription factors” (MTFs) can be subverted during tumorigenesis to control expression of oncogenic transcriptional programs. Current approaches to identify MTFs rely on chromatin immunoprecipitation-sequencing data, which is currently unavailable for many cancer types. We developed the CaCTS (Cancer Core Transcription factor Specificity) algorithm to prioritize candidate MTFs using pan-cancer RNA-sequencing data. more...

(Submitter supplied) Background: Fallopian tube secretory epithelial cells (FTSECs) have been implicated as a cell-of-origin for high-grade serous epithelial ovarian cancer. However, there are relatively few in vitro models of this tissue type available for use in studies of FTSEC biology and malignant transformation. In vitro three-dimensional (3D) cell culture models aim to recreate the architecture and geometry of tissues in vivo and restore the complex network of cell-cell/cell-matrix interactions that occur throughout the surface of the cell membrane. more...
