homeostasis/metabolism
• the transferrin-mediated iron uptake rate of reticulocyte-rich RBCs from 8 week old homozygous mutant mice is only about 30% that of such cells from wild-type mice
• upon reincubation with medium containing excess apo-transferrin, iron-laden erythrocytes from 8 week old homozygous mutant mice lose a significant proportion (17.8 +/- 3.3%) of the iron previously taken up by the cells
• at 8 weeks of age, the erythrocyte zinc-to-iron protoporphoryn IX ratio of homozygous mutant mice is approximately 3.5-fold that of wild-type mice
|
• the liver iron content of homozygous mutant mice is approximately 3-fold higher than that of wild-type mice
|
hematopoietic system
• the hematocrit of 8 week old mice homozygous for the targeted mutation is about 75% that of wild-type mice
|
• blood of 8 week old mice homozygous for the targeted mutation has a hemoglobin (g/dl) content about 64% that of blood from wild-type mice
|
• red blood cells of 8 week old homozygous mutant mice contain only about 39% as much hemoglobin (pg) as RBCs of wild-type mice
|
• the hemoglobin concentration in red blood cells from 8 week old homozygous mutant mice is about 82% that of wild-type mice
|
• 8 week old homozygous mutant mice have a mean RBC volume less than half that of wild-type mice
|
• red blood cells of homozygous mutants vary in shape and size
|
• the platelet count of 8 week old homozygous mutant mice is 4 times that of wild-type mice
|
• reticulocytes of 8 week old homozygous mutant mice contain only half the cellular hemoglobin of those from wild-type mice
|
• in blood of 8 week old homozygous mutant mice, both the absolute number and the proportion of reticulocytes are significantly elevated over those in blood of mice with at least one wild-type allele
|
liver/biliary system
• the liver iron content of homozygous mutant mice is approximately 3-fold higher than that of wild-type mice
