It is generally believed that gene-environment interaction may contribute to neurodegeneration. Of particular note is that iron overload may be one of the risk factors for neurodegeneration. However, the mechanisms underlying iron-associated neurotoxicity are not fully understood. Here we explored the effects of mechanistic target of rapamycin (mTOR) inhibition in iron-stressed human neuroblastoma...
Both monoamine oxidase B (MAO-B) and iron accumulation are associated with neurologic diseases including Parkinson’s disease. However, the association of iron with MAO-B activity was poorly understood. Here we took advantage of highly sensitive and specific fluorescence probes to examine the change in MAO-B activity in human dopaminergic neuroblastoma (SH-SY5Y) cells upon iron exposure. Both ferric...
Deregulated iron homeostasis is generally believed to be implicated in neurodegenerative diseases, including Parkinson’s disease. Nevertheless, it is not fully understood how iron overload can elicit neuronal cell damage. Here we examined mitochondrial reactive oxygen species (ROS) levels in human dopaminergic neuroblastoma SH-SY5Y cells upon iron exposure. A relatively high concentration of iron...
