amyloid beta deposits ( J:107132 )
• levels of insoluble amyloid beta42 are increased by 32% in the brains of mutants at 15 months of age compared to wild-type mice
• however, no changes in the levels of amyloid beta40 or amyloid beta42 is seen at 2-6 months of age
• these results indicate an age-dependent and selective increase in insoluble amyloid beta42 as observed in Alzheimer's patients

Reduced body weight and testicular atrophy in Pin1tm1Tuc/Pin1tm1Tuc mice

endocrine/exocrine glands
abnormal mammary gland growth during pregnancy ( J:74508 )
• failure to undergo lobuloalveolar development during pregnancy due to impaired development and proliferation of mammary epithelia cells
seminiferous tubule degeneration ( J:74508 )
• evident around 3.5 months of age
• more pronounced at 18 months of age, at which point mature sperm was undetected
decreased testis weight ( J:74508 )
• 44% reduction in testicular weight relative to wild-type by 3 to 5 months of age

growth/size/body
decreased body weight ( J:74508 )
• body weight was similar to that of wild-type until 3 months of age
• 29% reduction in body weight at 7 months of age relative to wild-type

reproductive system
azoospermia ( J:74508 )
• mature spermatocytes undetected in the seminiferous tubules at 18 months of age
abnormal mammary gland growth during pregnancy ( J:74508 )
• failure to undergo lobuloalveolar development during pregnancy due to impaired development and proliferation of mammary epithelia cells

vision/eye
increased susceptibility to age-related retinal degeneration ( J:74508 )
• approximately 50% of mice exhibited retinal degeneration at 4 to 6 months of age, with progression and increased penetrance at 16 months of age

integument
abnormal mammary gland growth during pregnancy ( J:74508 )
• failure to undergo lobuloalveolar development during pregnancy due to impaired development and proliferation of mammary epithelia cells

amyloid beta deposits ( J:107132 )
• levels of insoluble amyloid beta, especially amyloid beta42, are increased by 46% at 6 months of age compared to single Tg(APPSWE)2576Kha hemizygous controls
• however, levels of soluble amyloid beta40 and amyloid beta42 are not affected
• amyloid beta42 predominately accumulates in multivesicular bodies of neurons
• levels of total APPs and beta-APPs are increased by about 3-fold, but levels of alpha-APPs are reduced by about 50% compared to single Tg(APPSWE)2576Kha hemizygous controls, indicating an increase in amyloidogenic versus non-amyloidogenic APP processing and thus elevation of the amyloid beta42
