| Research Abstract |
This study investigated the effects of high phosphorus diet or iron deficient diet on bone metabolism by molecular nutritional procedure. High phosphorus diet increased mRNA expression of receptor activator of nuclear factor-kappaB ligand and decreased mRNA expressions of intestinal calcium absorption-related factors. Dietary iron deficiency decreased mRNA expressions of osteoblast-related factors and intestinal calcium absorption-related factors.
