Increase in storage iron content in Cptm1Hrs/Cptm1Hrs liver and spleen

homeostasis/metabolism
• homozygotes showed elevated serum ferritin
• aceruloplasminemic mice showed normal copper gastrointestinal absorption, hepatic uptake, and biliary copper excretion
• the copper content of brain, heart, spleen, and kidney was normal, and homozygotes exhibited normal copper-zinc superoxide dismutase activity in these tissues
• notably, hepatic copper content was significantly elevated in aceruloplasminemic mice
• ferrokinetic studies showed normal rates of iron absorption, initial tissue iron distribution, and plasma iron turnover
• no differences were detected in cellular iron uptake; however, homozygotes displayed a significant impairment in hepatocyte iron efflux
• at 1 year of age, there was no evidence of diabetes, anemia, or neurological deficits despite iron accumulation in these sites
• progressive accumulation of parenchymal iron, reaching a 3- to 6-fold increase in the iron content of the spleen by 1 year of age
• the spleen displayed normal cellular architecture with abundant iron in reticuloendothelial cells
• progressive accumulation of parenchymal iron, reaching a 3- to 6-fold increase in the iron content of the liver by 1 year of age (J:57730)
• the liver displayed normal cellular architecture with abundant iron in reticuloendothelial cells (J:57730)
• hepatic iron displayed a 3.5-fold increase in aceruloplasminemic mice due to loss of ferroxidase function (J:71807)

hematopoietic system
N
• the hemoglobin concentration remained normal relative to wild-type (J:57730)
• progressive accumulation of parenchymal iron, reaching a 3- to 6-fold increase in the iron content of the spleen by 1 year of age
• the spleen displayed normal cellular architecture with abundant iron in reticuloendothelial cells

liver/biliary system
• aceruloplasminemic mice showed normal copper gastrointestinal absorption, hepatic uptake, and biliary copper excretion
• the copper content of brain, heart, spleen, and kidney was normal, and homozygotes exhibited normal copper-zinc superoxide dismutase activity in these tissues
• notably, hepatic copper content was significantly elevated in aceruloplasminemic mice
• progressive accumulation of parenchymal iron, reaching a 3- to 6-fold increase in the iron content of the liver by 1 year of age (J:57730)
• the liver displayed normal cellular architecture with abundant iron in reticuloendothelial cells (J:57730)
• hepatic iron displayed a 3.5-fold increase in aceruloplasminemic mice due to loss of ferroxidase function (J:71807)

immune system
• progressive accumulation of parenchymal iron, reaching a 3- to 6-fold increase in the iron content of the spleen by 1 year of age
• the spleen displayed normal cellular architecture with abundant iron in reticuloendothelial cells
