Abstract Background Serum ferritin and hepatic iron concentrations are frequently elevated in patients who are chronically infected with the hepatitis C virus HCV and hepatic iron concentration has been used to predict response to interferon therapy but these correlations are not well understood. The HCV genome contains an RNA structure resembling an iron responsive element IRE in its internal ribosome entry site IRES structural domain IV dIV . An IRE is a stem loop structure used to control the expression of eukaryotic proteins involved in iron homeostasis by either inhibiting ribosomal binding or protecting the mRNA from nuclease degradation. The HCV structure located within the binding site of the 40S ribosomal subunit might function as an .
