Liver iron genes expression in Tfr2-deficient mice. Relative hepatic iron gene expression in (A) 10-week-old and (B) 14-day-old KI, KO, and LCKO-KI mice compared with age-matched WT sib pairs. Gene expression analysis was performed on 18 animals for Hepc transcripts and on at least 5 animals for strain for the other genes. *P < .05, **P < .01, and ***P < .001 versus WT. Bars represent SD in the analyzed animals group.
