homeostasis/metabolism
• significantly increased serum ferritin levels at 10 weeks of age
• significantly elevated transferrin saturation at 10 weeks of age
• 13.1-fold decrease in hepcidin mRNA expression in liver
• 2.4-fold increase in hepatic BMP6 mRNA levels
• marked up-regulation of ferroportin in the duodenum
• however, duodenal BMP6 mRNA expression is largely normal
• 2.4-fold reduction of nonheme iron levels in spleen at 10 weeks of age
• splenic macrophages are iron-deficient
• significantly increased serum iron levels at 10 weeks of age
• 12.9-fold increase of nonheme iron levels in liver at 10 weeks of age, as determined by ferrozine assay
• deposits of nonheme iron in parenchymal cells of the liver, pancreas, and heart at 10 weeks of age

hematopoietic system
• splenic macrophages are iron-deficient
• 2.4-fold reduction of nonheme iron levels in spleen at 10 weeks of age
• splenic macrophages are iron-deficient

liver/biliary system
• 12.9-fold increase of nonheme iron levels in liver at 10 weeks of age, as determined by ferrozine assay

immune system
• splenic macrophages are iron-deficient
