N	normal phenotype

endocrine/exocrine glands

decreased prostate gland tumor incidence ( J:67125 )

• rate of prostatic intra-epithelial neoplasia formation is similar to controls

• significantly fewer foci of invasive carcinomas at both 25 and 35 weeks

• tumors smaller than in controls

mortality/aging

premature death ( J:67125 )

• mortality due to prostate cancer

• survival time about 46.5 weeks as compared to 35-36 weeks for controls

neoplasm

decreased tumor incidence ( J:67125 )

• 70% are free of tumors at 35 weeks of age

decreased prostate gland tumor incidence ( J:67125 )

• rate of prostatic intra-epithelial neoplasia formation is similar to controls

• significantly fewer foci of invasive carcinomas at both 25 and 35 weeks

• tumors smaller than in controls

cardiovascular system

decreased angiogenesis ( J:67125 )

• less angiogenesis at 25 weeks of age

• lower microvascular density

cellular

cellular phenotype ( J:67125 )

N	• cellular proliferation rate equivalent to controls

♀	phenotype observed in females
♂	phenotype observed in males
N	normal phenotype

digestive/alimentary system

abnormal small intestine crypts of Lieberkuhn morphology ( J:43025 )

• 2- to 3-fold increase in the number of goblet cells in duodenal, jejunal, and ileal sections

• in distal jejunal sections the numbers of intermediate and granule goblet cells are increased

• however, mice do not develop intestinal tumors

decreased Paneth cell number ( J:43025 )

• 90 - 95% reduction in the number of Paneth cells at P28 and the area normally occupied by mature Paneth cells is partially filled with crypt base columnar cells as well as intermediate cells
