N normal phenotype
neoplasm
• mice show widespread peritoneal metastases, including omentum and diaphragm
• the overall metastatic tumor burden in fallopian tube-removed mice is less extensive than that of intact mice
• mice develop massive high-grade serous carcinomas that always arise from the fallopian tube
• however when fallopian tubes are removed, mice develop high-grade serous carcinomas originating from the ovary, indicating that the ovary can be a source of carcinomas but is less dominant in tumorigenesis than the fallopian tube
• ovary has on overgrowth of tumors composed of cells showing nuclear pleiomprhism, irregular chromatin distribution, macronucleoli, increased mitotic activity and widespread apoptosis resembling high-grade human serous ovarian cancer

mortality/aging
• premature death starting around 6 months of age with all mice dying by around 8 months of age
• fallopian tube-removed mice die at around 8-14 months of age after inducing ascites

homeostasis/metabolism

endocrine/exocrine glands
• ovary has on overgrowth of tumors composed of cells showing nuclear pleiomprhism, irregular chromatin distribution, macronucleoli, increased mitotic activity and widespread apoptosis resembling high-grade human serous ovarian cancer

reproductive system
• ovary has on overgrowth of tumors composed of cells showing nuclear pleiomprhism, irregular chromatin distribution, macronucleoli, increased mitotic activity and widespread apoptosis resembling high-grade human serous ovarian cancer
