In Vivo 1H NMR spectroscopy and qPCR method were used to investigate long-term effect of two different iron repletion therapy protocols on neurochemical profiles and gene expression in prefrontal cortex and hippocampus of neonatally iron deficient rats at adulthood. Region specific differences in NAA, NAAG, PE and GPC+PC were in agreement with observed gene expression. Observed dose-dependent effects of iron repletion protocol potentially may be helpful in optimizing therapy for neonatal iron deficiency.
