  Glutamate is an excitatory transmitter and can induce neurotoxicity, it can also increase the iron concentrations in the brain, but little is known about the detailed molecular regulation mechanism of iron metabolism by Glu. Based on our previous data, iron metabolism related proteins might be associated with the increase of brain iron contents induced by neurotransmitter. To investigate the issues, the iron contents, non-transferrin-bound iron (NTBI) uptake and the expression of iron uptake and iron release proteins were firstly examined in vivo and in vitro with iron histochemistry, inductively coupled plasma mass spectroscopy (ICP-MS), 55Fe radioactive liquid scintillation counting and western blot methods. Data showed that glutamate induced the increase of total iron contents, storage iron contents and NTBI uptake activity. Moreover, only divalent metal transporter 1, one of iron .. View More»
