Animal Models of Normal and Disturbed Iron and Copper Metabolism

Area of Science:

• Human physiology and pathophysiology
• Trace mineral metabolism
• Genetics and disease modeling

Background:

• Dysregulated iron and copper homeostasis cause common human diseases like anemia, iron overload, Menkes disease, and Wilson disease.
• Historically, rats were primary models, but mice are now prevalent due to genetic engineering.
• The shift to mouse models warrants critical evaluation of their suitability for human pathophysiology.

Purpose of the Study:

• To provide a guide for future research on human iron and copper-related disorders.
• To critically assess the utility of current animal models.
• To advocate for the development of complementary experimental models.

Main Methods:

• Literature review and synthesis of research trends in iron and copper metabolism.
• Analysis of historical and current animal models used in human disease research.
• Discussion of advancements in genetic engineering technologies for model generation.

Main Results:

• Mouse models are now dominant in iron and copper metabolism research due to genetic technologies.
• The appropriateness of mouse models for all human pathophysiology aspects requires careful consideration.
• New genetic technologies facilitate the creation of diverse mammalian models.

Conclusions:

• Future research should consider a broader range of animal models, including rats and swine, for studying human iron and copper disorders.
• Developing complementary models will accelerate the understanding of disease mechanisms.
• This approach will expedite the development of novel therapeutic strategies for these prevalent human conditions.
