mortality/aging
• most mice die by P14 with severe weight loss and nearly all mice die by weaning
• however, postnatal lethality can be rescued by intraperitoneal injection of copper
|
homeostasis/metabolism
• copper levels are reduced in the heart, brain, kidney and spleen to 18%, 20%, less than 40% and 70%, respectively, of wild-type levels
• copper levels are over 8-fold higher in intestinal epithelial cells compared to wild-type
|
• serum copper levels are less than 40% of wild-type
|
• copper content in the liver reduced to 5% of wild-type
|
• iron content in the liver is increased 4-fold compared to in wild-type mice
|
cardiovascular system
• cardiac tissue exhibits large vacuoles and swollen mitochondria not present in wild-type cardiac tissue
• however, abnormal cardiac tissue morphology can be partially rescued by intraperitoneal injection of copper
|
• hearts are enlarged 20% compared to wild-type
• cardiac hypertrophy occurs at 2 weeks of age
|
growth/size/body
• hearts are enlarged 20% compared to wild-type
• cardiac hypertrophy occurs at 2 weeks of age
|
• at P14, mice weigh 4 g instead 9 g for wild-type mice
|
weight loss
(
J:129741
)
• mice die with severe weight loss
• however, postnatal weight lose can be rescued by intraperitoneal injection of copper
|
• mice exhibit poor growth beginning at day 10
|
behavior/neurological
hematopoietic system
• spleen weight adjusted for decreased body weight is less than in wild-type mice
|
pigmentation
liver/biliary system
• copper content in the liver reduced to 5% of wild-type
|
immune system
• spleen weight adjusted for decreased body weight is less than in wild-type mice
|
integument
• whiskers are kinked and brittle
|
loose skin
(

)
• skin laxity
