Iron 25-29 aconitase 1 Mus musculus 33-58 11341946-2 2001 In this paper, we have investigated the effect of hyperoxia and iron on the binding activity of IRP-1 and the ferritin synthesis in mouse peritoneal macrophages. Iron 64-68 aconitase 1 Mus musculus 96-101 11341946-4 2001 Iron diminished the IRP-1-binding activity and the enhanced synthesis of ferritin. Iron 0-4 aconitase 1 Mus musculus 20-25 11341946-6 2001 Consistently, hypoxia-induced loss of binding activity of IRP-1 and the enhanced synthesis of ferritin were blocked in the presence of an iron chelator deferoxamine. Iron 138-142 aconitase 1 Mus musculus 58-63 11341946-7 2001 These alterations of the binding activity of IRP-1 in response to oxygen and iron were not reproduced in the cell-free extract. Iron 77-81 aconitase 1 Mus musculus 45-50 11341946-8 2001 The data suggest that in the macrophages oxygen and iron inversely act on the binding activity of IRP-1 and the ferritin synthesis, and that intracellular mechanism(s) to sense iron and/or oxygen is required for these actions. Iron 52-56 aconitase 1 Mus musculus 98-103 11341946-8 2001 The data suggest that in the macrophages oxygen and iron inversely act on the binding activity of IRP-1 and the ferritin synthesis, and that intracellular mechanism(s) to sense iron and/or oxygen is required for these actions. Iron 177-181 aconitase 1 Mus musculus 98-103
