TFRC and hemochromatosis type 1: Our gene expression data revealed several genes (Hfe [Del-Castillo-Rueda et al., 2012], Slc40a1 [Del-Castillo-Rueda et al., 2012], Hmox1 [Song et al., 2012], Tfrc [Del-Castillo-Rueda et al., 2012] and Gdf15 [Cui et al., 2014]) directly involved in hemochromatosis and iron overload to be upregulated in our FRDAkd mice, all of which were rescued to normal levels by frataxin restoration.
