Increased hepcidin in transferrin-treated thalassemic mice correlates with increased liver BMP2 expression and decreased hepatocyte ERK activation.
Iron overload results in significant morbidity and mortality in β-thalassemic patients. Insufficient hepcidin is implicated in parenchymal iron overload in β-thalassemia and approaches to increase hepcidin have therapeutic potential. We have previously shown that exogenous apo-transferrin markedly ameliorates ineffective erythropoiesis and increases hepcidin expression in Hbb(th1/th1) (thalasse...
متن کاملHepcidin as a therapeutic tool to limit iron overload and improve anemia in β-thalassemic mice.
Excessive iron absorption is one of the main features of β-thalassemia and can lead to severe morbidity and mortality. Serial analyses of β-thalassemic mice indicate that while hemoglobin levels decrease over time, the concentration of iron in the liver, spleen, and kidneys markedly increases. Iron overload is associated with low levels of hepcidin, a peptide that regulates iron metabolism by t...
متن کاملRNA repair restores hemoglobin expression in IVS2-654 thalassemic mice.
Repair of beta-globin pre-mRNA rendered defective by a thalassemia-causing splicing mutation, IVS2-654, in intron 2 of the human beta-globin gene was accomplished in vivo in a mouse model of IVS2-654 thalassemia. This was effected by a systemically delivered splice-switching oligonucleotide (SSO), a morpholino oligomer conjugated to an arginine-rich peptide. The SSO blocked the aberrant splice ...
متن کاملHepcidin is decreased in TFR2 hemochromatosis.
The hepatic peptide hepcidin is the key regulator of iron metabolism in mammals. Recent evidence indicates that certain forms of hereditary hemochromatosis are caused by hepcidin deficiency. Juvenile hemochromatosis is associated with hepcidin or hemojuvelin mutations, and these patients have low or absent urinary hepcidin. Patients with C282Y HFE hemochromatosis also have inappropriately low h...
متن کاملDecreased renal mRNA expression of TRPM6 is associated with hypomagnesemia in C57BL/6 asthmatic mice.
BACKGROUND AND OBJECTIVES Hypomagnesemia has been reported up to 40% in asthma patients, and a relationship between hypomagnesemia and asthma severity has been previously characterized. However, the mechanism for hypomagnesemia in asthma patients is not clear. Transient receptor potential melastatin 6 (TRPM6) is a newly identified channel that is involved in active epithelial magnesium transpor...
