neoplasm
• fallopian tube cancers subsequently spread to envelop the ovaries and then aggressively metastasize throughout the abdominal cavity, including the mesentery and pancreas, with prominent cancer lesions on the diaphragm and peritoneal membrane
• females develop early high-grade serous carcinomas in the fallopian tube
• tumors are characterized by complex papillae and glands forming slit-like spaces nad solid sheets of tumor cells with pleomorphic nuclei, prominent nucleoli, and high mitotic activity, resembling high-grade human serous ovarian cancer
• origin of the serous carcinomas, however is the fallopian tube

mortality/aging
• after developing ascites, 100% of females die from the metastatic cancers between 6.5 and 13 months of age

reproductive system
• tumors are characterized by complex papillae and glands forming slit-like spaces nad solid sheets of tumor cells with pleomorphic nuclei, prominent nucleoli, and high mitotic activity, resembling high-grade human serous ovarian cancer
• origin of the serous carcinomas, however is the fallopian tube
• abnormal proliferation begins in the stromal compartment, not in the epithelial layer, of the fallopian tube; tumor cells in the stroma express epithelial markers indicating that stromal cells in the fallopian tube undergo a transition to an epithelial cell type during carcinoma formation

homeostasis/metabolism

endocrine/exocrine glands
• tumors are characterized by complex papillae and glands forming slit-like spaces nad solid sheets of tumor cells with pleomorphic nuclei, prominent nucleoli, and high mitotic activity, resembling high-grade human serous ovarian cancer
• origin of the serous carcinomas, however is the fallopian tube
