英文摘要 | Neuronal iron homeostasis disruption and oxidative stress are closely related to the pathogenesis of parkinson's disease (pd). adult iron-regulatory protein 2 knockout (ireb2(-/-)) mice develop iron accumulation in white matter tracts and nuclei in different brain area and display severe neurodegeneration in purkinje cells of the cerebrum. mitochondrial ferritin (mtft), a newly discovered ferritin, specifically expresses in high energy-consuming cells, including neurons of brain and spinal cord. interestingly, the decreased expression of mtft in cerebrum, but not in striatum, matches the differential neurodegeneration pattern in these ireb2(-/-) mice. to explore its effect on neurodegeneration, the effects of mtft expression on 6-hydrodopamine (6-ohda)-induced neuronal damage was examined. the overexpression of mtft led to a cytosolic iron deficiency in the neuronal cells and significantly prevented the alteration of iron redistribution induced by 6-ohda. importantly, mtft strongly inhibited mitochondrial damage, decreased production of the reactive oxygen species and lipid peroxidation, and dramatically rescued apoptosis by regulating bcl-2, bax and caspase-3 pathways. in conclusion, this study demonstrates that mtft plays an important role in preventing neuronal damage in an 6-ohda-induced parkinsonian phenotype by maintaining iron homeostasis. regulation of mtft expression in neuronal cells may provide a new neuroprotective strategy for pd. antioxid. redox signal. 13, 783-796. |
