Randomized trial shows hepcidin overexpression causes severe iron deficiency anemia in transgenic mice, suggesting its role in iron regulation.

Investigate the impact of hepcidin overexpression on iron levels and related phenotypes in transgenic mice.
Generated transgenic mice expressing hepcidin via the transthyretin promoter.
Observed physical characteristics and blood parameters at birth.
Identified survivors and examined erythrocyte morphology.
Most transgenic mice exhibited pale skin and died within hours of birth.
Transgenic mice showed severe microcytic hypochromic anemia with decreased body iron levels.
Surviving mice displayed marked erythrocyte abnormalities including anisocytosis and hypochromia.

Nicolas et al. (2002) studied this question.
