cellular
|
• swollen mitochondria and broken mitochondrial double membranes are observed
• hearts have increased mitochondrial mass, as well as greater area and number
|
|
• respiratory control ratio (RCR) and state 3 respiration are significantly impaired in mitochondria
|
cardiovascular system
|
• hearts have many focal areas of damage with swollen mitochondria, mottled matrix and broken mitochondrial double membranes
|
|
• progressive increase in renal vascular resistance beginning at 3 months of age
|
|
• diastolic blood pressure is elevated in conscious mutants at 3 months of age when measured using a tail-cuff monitor
• by 8 months of age, both diastolic and systolic blood pressure is increased in conscious mutants
• under anesthesia, when measured by intravascular connulation, mutants exhibit a similar blood pressure to anesthetized controls, however this is reduced compared to conscious mutants
|
homeostasis/metabolism
adipose tissue
|
• loss of fat tissue by 5 months of age
|
growth/size/body
N |
• mutants exhibit normal weight gain and body weight
|
|
• loss of fat tissue by 5 months of age
|
|
• 2-fold increase in kidney weight between 2 and 5 months of age
|
liver/biliary system
renal/urinary system
|
• progressive increase in renal vascular resistance beginning at 3 months of age
|
|
• albumin excretion rate increases progressively with age and exceeds 15,000 ug/24 hr at 9 months of age
|
|
• kidney shows dilation of the ducts, atrophy of tubular cells, protein casts in the duct lumen, and prominent infiltration of mononuclear cells
|
|
• 2-fold increase in kidney weight between 2 and 5 months of age
|
|
• glomeruli exhibit a thickened and irregular basement membrane
|
|
• expanded mesangium showing enlarged mesangial fraction and mesangial volume, with the greatest rate increase during 2.5-6 months of age
|
|
• diffuse and nodular expansion of mesangial matrix in mutants over 2 months of age
|
|
• diffuse and nodular glomerulosclerotic lesions
• nodules are acellular and are similar to Kimmelsteil-Wilson lesions in size
|
|
• glomerular volume is enlarged, with the greatest rate increase during 2.5-6 months of age
|
|
• seen in many mutants over 5 months of age
|
|
• expansion of kidney tubules; average cortical tubule cross-sectional area (minus the lumen) is 34% greater in 9 month old mutants than controls
|
|
• significant fibrosis in the kidney by 5 months of age
|
|
• tubulointerstitial fibrosis
|
|
• many mutants over 5 months of age exhibit bladder stasis
|
|
• distended bladders are seen in many mutants over 5 months of age
|
|
• glomerular filtration rate increases significantly from 2 to 3 months of age but then decreases significantly from 5 to 9 months of age
• decline in glomerular filtration rate coincides with an increase in renal vascular resistance
