N normal phenotype
endocrine/exocrine glands
• vacuolization of the cortical cell cytoplasm is seen in 4 month old adrenal glands, with vacuolization more apparent in females than males at this time
• cells of the cortex are vacuolated to varying degrees in the adrenals of 13-16 month old mice
• cortex thickness of the adrenal gland of 13-16 month old mice is reduced
• mean weight of adrenal glands increases with age and is statistically significant at 9 and 12 months of age
• 1 of 3 females show minimal apparent medullary hyperplasia in the adrenal glands at 4 months of age
• adrenals of 13-16 month old mice show nodular hyperplasia of the medulla
• size of adrenal gland is increased in 13-16 month old mice
• neoplastic changes in pituitary are seen after 9 months of age and mice develop pituitary tumors with complete penetrance and a long latency with lifespan of about 14 months
• tumors resemble adenoma (groups and cords of tumor cells nestled around centrally located blood vessels)

growth/size/body
• weight loss after 9 months of age for males and 12 months for females
• mice weigh more than controls at 9 months of age, but begin wasting at about 1 year of age

neoplasm
• neoplastic changes in pituitary are seen after 9 months of age and mice develop pituitary tumors with complete penetrance and a long latency with lifespan of about 14 months
• tumors resemble adenoma (groups and cords of tumor cells nestled around centrally located blood vessels)

mortality/aging
• lifespan of about 14 months, with mean age of autopsy of 15.5 months for males and 13.1 months for females

behavior/neurological
• mice develop an unsteady gait when they become clinically ill

homeostasis/metabolism
• mice show increased ACTH plasma levels

integument
• clinically ill mice show loss of hair

nervous system
• neoplastic changes in pituitary are seen after 9 months of age and mice develop pituitary tumors with complete penetrance and a long latency with lifespan of about 14 months
• tumors resemble adenoma (groups and cords of tumor cells nestled around centrally located blood vessels)

renal/urinary system
• enlarged penis

reproductive system
• enlarged penis
• enlarged scrotal pads

skeleton
• mice develop a spinal hump in the thoracic region when they become clinically ill
