Strategies for Inducing and Validating Zinc Deficiency and Zinc Repletion

Area of Science:

• Nutritional Science and Metabolism
• Animal Physiology and Disease Models

Background:

• Growing evidence links zinc's role in disease onset and progression.
• A critical need exists for reliable methods to modulate zinc homeostasis.
• Current research requires robust models to study zinc's physiological impact.

Approach:

• Developed validated dietary strategies to manipulate whole-body zinc levels in mice.
• Utilized accessible and cost-effective methods applicable across species.
• Evaluated animal growth rates, plasma, and urine zinc levels for confirmation.

Key Points:

• Successfully altered zinc homeostasis through dietary interventions in a preclinical model.
• Established reliable biomarkers (growth, plasma/urine zinc) for assessing zinc status.
• Methodology ensures reproducibility and scientific rigor in zinc-related research.

Conclusions:

• Provided validated, cost-effective dietary strategies for modulating zinc levels in mice.
• Enhances the ability to investigate zinc deficiency and repletion effects on disease.
• Promotes standardization and reproducibility in zinc metabolism research.
