• a small number of tubules were distended with colloid casts at 10 to 14 weeks of age
• in the fully developed case in 4 to 6 months old mice, many of the tubules were dilated and atrophied in some places
|
renal cast
(
J:5232
)
• a small number of tubules were distended with colloid casts at 10 to 14 weeks of age
|
• at necropsy
|
pale kidney
(
J:5232
)
• at necropsy
|
behavior/neurological
polydipsia
(
J:5232
)

|
• mice become hunched at a few months of age
|
growth/size/body
weight loss
(
J:5232
)
• at the age of 4-6 months
• progressively worse until death
|
• cysts were seen only in kidneys with very advanced lesions
(J:5232)
• microcystic formations
(J:197578)
|
homeostasis/metabolism
• 1 month old mutants show CoQ9 levels that are 20% of controls in the brain, 28% in the kidney, 62% in the liver and 35% in the muscle
• 4 month old mutants show even further reduced levels of CoQ9, levels that are 16% of controls in the brain, 21% in the kidney, 25% in the muscle
• 6 month old mutants show CoQ9 levels that are 28% of controls in the brain, 14% in the kidney, 68% in the liver, and 20% in the muscle
• liver of 4 month old mutants has increased CoQ9; 157% of controls
|
• urine became colorless as the animal aged
|
albuminuria
(
J:5232
)
• increase in urinary protein at about 10 weeks of age
|
cellular
• levels of mitochondrial DNA are decreased in the kidney (19%) at 4 months of age
• levels of mitochondrial DNA are decreased in the kidney (26%) and liver (71%) at 6 months of age
|
• levels of mitochondrial DNA are increased in the brain (128%), and liver (120%) at 4 months of age
|
• coenzyme Q (CoQ)-dependent complex I + III activity, normalized to citrate synthase activity, is reduced in the kidney at 4 and 6 months of age, and in the muscle at 6 months of age
• CoQ-dependent complex I + III activity, normalized to CS activity, is increased in the liver at 4 months of age, but not at 6 months
• CoQ-depended complex II + III activity, normalized to CS activity, is reduced in the kidney, brain, and liver, and slightly increased in the muscle of 1 month old mutants
• CoQ-depended complex II + III activity, normalized to CS activity, is reduced in the muscle at 6 months of age
• cytochrome c oxidase and citrate synthase activities are increased in the liver a 4 months of age
• citrate synthase activity is decreased in the kidney at 6 months of age
|
• ATP concentration and ATP/ADP ratio are decreased in the kidney, slightly decreased in muscle, and slightly increased in the brain and liver at 4 months of age
• ATP levels and ATP/ADP ratio are decreased in the kidney and brain but are increased in the liver and muscle at 6 months of age
|
• mutants show elevated reactive oxygen species (ROS) production in the kidney (at 1 and 4 months of age) and muscle (at 4 months of age, but not 6 months of age) following dihydroethidine injection compared to wild-type controls
• markers of oxidative stress are increased in sclerotic glomeruli, dilated tubuli, microcystic formations, and in some of the normal proximal and distal tubuli adjacent to affected areas at 6 months of age
|
immune system
