Abstract:
Background
Every cell of the mammalian organism needs iron in numerous oxido-reductive processes as well as fo r transport and storage of oxygen. The versatility of ionic iron makes it a toxic entity which can catalyze the production of radicals that damage vital membranous and macromolecular assemblies in t he cell. The mammalian organism maintains therefore a complex regulatory network of iron uptake, ex cretion and intra-body distribution. Intracellular regulation in different cell types is intertwine d with a global hormonal signaling structure. Iron deficiency as well as excess of iron are frequen t and serious human disorders. They can affect every cell, but also the organism as a whole.
Results
Here, we present a kinematic model of the dynamic system of iron pools and fluxes. It is based on f errokinetic data and chemical measurements in C57BL6 wild-type mice maintained on iron-deficient, i ron-adequate, or iron-loaded diet. The tracer iron levels in major tissues and organs (16 compartme nt) were followed for 28 days. The evaluation resulted in a whole-body model of fractional clearanc e rates. The analysis permits calculation of absolute flux rates in the steady-state, of iron distr ibution into different organs, of tracer-accessible pool sizes and of residence times of iron in th e different compartments in response to three states of iron-repletion induced by the dietary regim e.
Conclusions
This mathematical model presents a comprehensive physiological picture of mice under three differen t diets with varying iron contents. The quantitative results reflect systemic properties of iron me tabolism: dynamic closedness, hierarchy of time scales, switch-over response and dynamics of iron s torage in parenchymal organs. Therefore, we could assess which parameters will change under dietary perturbations and study in quantitative terms when those changes take place.
