Transferrin saturation, plasma iron turnover, and transferrin uptake in normal humans.
The relationship between plasma iron, transferrin saturation, and plasma iron turnover was studied in 53 normal subjects whose transferrin saturation varied between 17% and 57%, in 25 normal subjects whose transferrin saturation was increased by iron infusion to between 67% and 100%, and in five subjects with early untreated idiopathic hemochromatosis whose transferrin saturation was continuall...
متن کاملIron Uptake from Rat Plasma Transferrin
iron release between fast and slow diferric transferrins and between fast and slow monoferric transferrins when incubated with reticulocytes or injected in vivo showed no significant difference in the behavior of the two isotransferrin species. Reticulocyte uptake of diferric transferrin resulted in the removal of both iron atoms from the transferrin molecule. A twofold greater iron uptake was ...
متن کاملThe plasma clearance and liver uptake of iron from transferrin of low and high iron saturation.
I. Serum labelled with radioactive iron was adjusted to different degrees of iron saturation and clearance of the tracer from the circulation of rats and its uptake by liver and intestine were followed. 2. The results showed that: (a) plasma iron clearance did not vary according to whether labelled iron was attached to transferrin at high or low iron saturation; (b) uptake of labelled iron by t...
متن کاملIron uptake from rat plasma transferrin by rat reticulocytes.
Fast and slow rat transferrins were isolated by isoelectric focusing and prepared in their di- and monoferric forms. A comparison of the rates of iron release between fast and slow monoferric transferrins when incubated with reticulocytes or injected in vivo showed no significant difference in the behavior of the two isotransferrin species. Reticulocyte uptake of diferric transferrin resulted i...
متن کاملTransferrin receptor 2 mediates uptake of transferrin-bound and non-transferrin-bound iron.
BACKGROUND/AIMS Transferrin receptor 2 appears to have dual roles in iron metabolism; one is signalling, the other is iron transport. It is sensitive to high levels of diferric transferrin, which is associated with disorders of iron overload. Also present in these disorders are increased levels of plasma non-transferrin-bound iron. This study sought to clarify the role of transferrin receptor 2...
