22. findings show that HFE is present in substoichiometric concentrations with respect to both TfR1 and TfR2 in liver tissue; finding supports a model, in which availability of HFE is limiting for formation of complexes with TfR1 or TfR2 PMID: 19819738
23. Hepcidin mRNA expression in vitro is highly sensitive to the presence of serum factors and PI3 kinase inhibition and parallels TfR2 expression PMID: 19924283
