reproductive system
• large, irregular cells, occasionally forming cryptic glandular structures
• prostate epithelial dysplasia
• focal areas of epithelial hyperplasia (J:86212)
• increased proliferation of epithelial cells (J:86212)
• mutant prostates contain a 20-fold increase in senescent epithelial cells compared to wild-type prostates (J:100683)
• massive enlargement of all prostatic lobes evident at 2 to 3 months of age, complete penetrance
• tumors were undifferentiated and often affected multiple lobes, suggesting multifocal origns (J:86212)
• complete penetrance of invasive and diffuse prostate cancer with disruption of basement membrane and signs of organ infiltration (J:86212)
• invasive prostatic cancer develops after a 4-6 month latency; however none of the mutants had died of prostatic cancer by 10 months of age (J:100683)
• tumors retain clearly defined urogenital organ boundaries (J:100683)
• high-grade prostatic intraepithelial neoplasia are seen in all 3 prostatic lobes in 9-week old mutants (J:100683)
(J:163589)
• that does not progress to grossly invasive disease (J:200002)
• mice develop diffuse, highly proliferative high-grade prostatic intraepithelial neoplasia without invasive cancer but with cystic enlargement of the anterior prostate (J:239660)
