Expression of hemojuvelin (HJV) in skeletal muscle (A), heart (B) and liver (C). Q-RT-PCR analysis of HJV mRNA levels in control versus iron overloaded mice of 3 strains (Balb/c, C57BL/6, DBA2). The result values are expressed as mean of triplicate runs +/- standard deviation. Statistical significant differences relative to control diet fed mice were determined. *p < 0,05; **p < 0,01; ***p < 0,001. F = female; M = male.
