Research Abstract	Iron is an essential mineral for the body and its deficient is the problem in the world. In Japan, about 10% of women suffer from iron-deficient anemia, and 20-40% from non-anemic iron deficiency. Iron is also the risk factor of oxidative stress when accumulated in the organs excessively. In this study, by the global analysis of gene expression, a variety of metabolic processes tended to change in the liver of non-anemic iron deficient rats. Also, it was revealed that gene expression patterns in the liver and the blood cells, were changed in rats fed iron-excess diet.
