mortality/aging
• 11% of mice die between 2 and 14 months of age; some show signs of systemic infection, whereas others show necrotizing arteritis in multiple organs, severe glomerulonephrits, severe nephropathy, and anemia
• some animals develop tumors and die prematurely
|
cardiovascular system
• some mice show a vasculitis syndrome
|
• 20% of mice dying before or sacrificed at 2 years of age develop arteritis in single or multiple organs
• arteritis is found in large vessels and small arteries, veins and capillaries
• multiple organs like the heart, kidney, liver, lung pancreas, spleen, lymph nodes, thyroid, gall bladder, tongue, spinal cord muscles, and omentum show arteritis; some mice develop necrotizing arteritis in pancreas, liver, spleen, small intestine, ovary, uterus, urethra, and spinal cord
• some arteritic lesions show infiltration of entire vessel with fibrinoid necrosis
|
hematopoietic system
• 2 mice showing arteritis and/or glomerulonephritis had low red blood cell counts
|
immune system
• 20% of mice dying before or sacrificed at 2 years of age develop arteritis in single or multiple organs
• arteritis is found in large vessels and small arteries, veins and capillaries
• multiple organs like the heart, kidney, liver, lung pancreas, spleen, lymph nodes, thyroid, gall bladder, tongue, spinal cord muscles, and omentum show arteritis; some mice develop necrotizing arteritis in pancreas, liver, spleen, small intestine, ovary, uterus, urethra, and spinal cord
• some arteritic lesions show infiltration of entire vessel with fibrinoid necrosis
|
• some mice which died prematurely showed arteritis, severe kidney abnormalities and anemia which are hallmarks of autoimmune disorder whereas wild-type mice did not display any of these
|
• circulating autoreactive nuclear antibodies are detected
|
• severe glomerulonephritis sometimes associated with extensive tubular cast formation
|
renal/urinary system
• glomerular lesions often include membranoproliferative changes, wire-loop-like subendothelial deposits, and intracapillary thrombi that often obstruct the capillary lumen
|
• severe glomerulonephritis sometimes associated with extensive tubular cast formation
|
renal cast
(
J:119985
)
• severe glomerulonephritis sometimes associated with extensive tubular cast formation
|
neoplasm
• no distinct tumor pattern is observed in organs outside the hematopoietic system
|
• ~23% of mice develop mixed hemangioma/hemangiosarcoma or either independently compared to ~4% in wild-type
|
• one female presented an erythroleukemia
|
• 2 mice develop types of lymphomas at 8 and 12 months of age, respectively compared to 0 tumors in wild-type mice
|
homeostasis/metabolism
adipose tissue
• one mouse presenting with vasculitis syndrome developed fat necrosis
