In a time-line experiment, we showed that heme loading of macrophages decreased the expression of heme–hemopexin complex receptor and transferrin receptor 1 (TfR1) (Fig. 4D), while ferritin levels remained largely unchanged except for an increase in ferritin levels at 16 h post-treatment (Fig. 4D).

Expectedly, and in line with previous report (13), treatment of macrophages with DFO abolished ferroportin and ferritin induction by heme, whereas TfR1 expression was lowered upon heme and combined treatment with heme and DFO (Fig. 7D). PubMed:29212341
Moreover, in CMs the heme-mediated induction of the iron exporter Ferroportin (Fpn) was abrogated by Hx treatment while the down-regulation of the iron importer Transferrin receptor 1 (TfR1) was significantly reduced by Hx (see Figure 3 in [37]) further indicating that Hx limits heme-iron accumulation within the cell.

Moreover, the mRNA levels of Fpn and Flvcr1a were increased in Hx-/- mice, whereas those of the iron importers Divalent Metal Transporter 1 (Dmt1) and Tfr1 were decreased (see Figure 4 in [37]). PubMed:28400318
However, the mRNA and protein expression of both TFR1 and DMT1 responsible for iron entry into renal cells were slightly decreased, although not reaching statistical significance (Online Supplementary Figure S4). PubMed:28143953
