In the last decade, new evidence has challenged the dogma that the ovary is the main source of this cancer. The fallopian tube has been proposed instead as the primary origin of high-grade serous ovarian cancer, the subtype causing 70% of ovarian cancer deaths. By conditionally deleting\n                    <jats:italic>Dicer<\/jats:italic>\n                    , an essential gene for microRNA synthesis, and\n                    <jats:italic>Pten<\/jats:italic>\n                    , a key negative regulator of the PI3K pathway, we show that high-grade serous carcinomas arise from the fallopian tube in mice. In these\n                    <jats:italic>Dicer<\/jats:italic>\n                    -\n                    <jats:italic>Pten<\/jats:italic>\n                    double-knockout mice, primary fallopian tube tumors spread to engulf the ovary and then aggressively metastasize throughout the abdominal cavity, causing ascites and killing 100% of the mice by 13 mo. Besides the clinical resemblance to human serous cancers, these fallopian tube cancers highly express genes that are known to be up-regulated in human serous ovarian cancers, also demonstrating molecular similarities. Although ovariectomized mice continue to develop high-grade serous cancers, removal of the fallopian tube at an early age prevents cancer formation\u2014confirming the fallopian tube origin of the cancer. Intriguingly, the primary carcinomas are first observed in the stroma of the fallopian tube, suggesting that these epithelial cancers have a mesenchymal origin. Thus, this mouse model demonstrates a paradigm for the origin and initiation of high-grade serous ovarian carcinomas, the most common and deadliest ovarian cancer.\n                  <\/jats:p>","DOI":"10.1073\/pnas.1117135109","type":"journal-article","created":{"date-parts":[[2012,2,14]],"date-time":"2012-02-14T00:11:40Z","timestamp":1329178300000},"page":"3921-3926","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":325,"title":["High-grade serous ovarian cancer arises from fallopian tube in a mouse model"],"prefix":"10.1073","volume":"109","author":[{"given":"Jaeyeon","family":"Kim","sequence":"first","affiliation":[{"name":"Departments of Pathology and Immunology,"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donna M.","family":"Coffey","sequence":"additional","affiliation":[{"name":"Department of Pathology and Laboratory Medicine, The Methodist Hospital and Weill Medical College of Cornell University, Houston, TX 77030"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chad J.","family":"Creighton","sequence":"additional","affiliation":[{"name":"Medicine,"},{"name":"Dan L.
