WebMay 21, 2010 · These homologous proteins are important for mitochondrial iron uptake in erythroid and nonerythroid cells, respectively (60, 61) (Fig. 1A). Mitoferrin-1 is localized on the inner mitochondrial membrane and functions as an essential importer of iron for mitochondrial heme and ISC in erythroblasts and is necessary for erythropoiesis ( 60 ). WebIron uptake by BEL-7402 cells was also significantly higher than that by HL7702 cells. Though the higher dose of FA-MNPs resulted in the higher intracellular iron uptake, the intracellular uptake of iron reached a peak when the dose of FA-MNPs was more than 1.0 mg/mL. This suggested that apoptosis may not be proportional to the FA-MNP doses but ...
