reproductive system
N
• adult males are fertile, have many normal sperm present in the epididymis, and show normal distribution of vimentin filaments in Sertoli cells (SCs) at 2 months of age, suggesting normal SC cytoskeletal organization
• 70% reduction in sperm count at 2 months of age
• adult mice display only mild morphological alterations in the seminiferous tubules
• 60% reduction in testis weight at 2 months of age
• 54% reduction in epididymis weight at 2 months of age

mortality/aging
• most die at 5-6 weeks of age

nervous system
• increase in the number of oligodendrocyte precursors in the cortex and hippocampus at 3 weeks of age
• a decrease in brain weight is detected at P5-P9 but not at P1
• by 2-3 weeks of age brain weight is about 50% that of controls
• at 4 weeks of age cortical thickness is about 65% that of controls
• however, no reduction in neuronal counts is detected at P1, P5 or P28
• the number of mature oligodendrocytes is reduced by 60-70% in multiple regions of the brain, including the corpus callosum, cortex, and hippocampus
• the total number of oligodendrocytes (OLIG2+ cells) is reduced especially in the corpus callosum and to a lesser extent in the cortex and hippocampus
• widespread loss of fine myelin binding protein reactive fibers in all cortical layers and in neuropil regions of the hippocampus
• decrease in the number of meylinated axons in the corpus callosum
• prominent at 4 weeks of age
• reduced levels of myelin proteins are detected throughout the brain
• decrease in myelination in the dense white matter tracts
