cardiovascular system
• 6- to 12-month-old mice, to a larger extent in older mice
|
• severe mitochondrial structural defects including inter-mitochondrial vacuoles, cristae disorganization and blebbing, and extensive cristolysis that are more pronounced in the left ventricle
• some abnormal nuclei shape and positioning (unusually attached to the mitochondrial
• however, sarcomeres are well-aligned and organized
|
• discontinuous, fragmented, and disorganized
|
• 9- to 12-month-old mice
|
• 6- to 12-month-old mice, to a larger extent in older mice
|
• female mice are more affected than male mice
|
behavior/neurological
N |
• male mice exhibit normal recognition and spatial memory and performance in an elevated plus maze
|
• in male mice with decreased exploration in an open field
|
• in male mice
|
• lack of preference for the conspecific in male mice
• however, social novelty preference is normal
|
nervous system
• 3-month-old mice exhibit less compact neuropil with ultrastructural abnormalities, fewer presynaptic vesicles, fewer neurofilaments, and fragmented mitochondrial at synaptic junctions, and abnormal accumulation of membranous interconnected tubules compared with wild-type mice
|
• swollen with fragmented and degenerating mitochondrial and disorganized neurofilaments in the molecular layer of 3-month-old mice
|
• subtle in male mice
|
homeostasis/metabolism
• decreased dopamine turnover in the striatum
• increased dopamine turnover in the prefrontal cortex
|
• in the striatum and prefrontal cortex
|
muscle
• severe mitochondrial structural defects including inter-mitochondrial vacuoles, cristae disorganization and blebbing, and extensive cristolysis that are more pronounced in the left ventricle
• some abnormal nuclei shape and positioning (unusually attached to the mitochondrial
• however, sarcomeres are well-aligned and organized
|
• discontinuous, fragmented, and disorganized
|
• female mice are more affected than male mice
|
• severe mitochondrial defects
|
• severe mitochondrial defects, especially in the soleus
|
• dilated with loss of SR-mitochondrial contact sites
|
pigmentation
• in the cerebellum of 3-month-old mice
|
limbs/digits/tail
• severe mitochondrial defects
|
• severe mitochondrial defects, especially in the soleus
|
cellular
• 6- to 12-month-old mice, to a larger extent in older mice
