N normal phenotype
muscle
N
• no obvious pathology in younger mice
• occasional muscle fiber splitting
• occasional angulated atrophic fibers
• occasional diffusely basophilic sarcoplasm
• occasional regenerating muscle fibers in exercising mice
• variation in muscle fiber size in older mice
• frequent internalized nuclei

nervous system
• giant axons found in sciatic nerve and anterior column of spinal cord
• number of giant axons increases in older mice
• giant axons filled with irregularly bundled neurofilaments
• clusters of microtubules, dense lamellar bodies, and membranous structures
• myelin sheaths irregular over internodes of giant axons with extended gaps
• myelin sheaths of giant axons thinner than expected
• some small nerve fibers with thicker myelin sheaths than expected
