Gene expression profile analysis in cultured human neuronal cells after static magnetic stimulation

Abstract

Although the magnetic force has been used in various human environments and medicines, their influence on the nervous system has not been fully elucidated. In this study, we investigated mRNA expressions profiles of neuronal cells after the application of static magnetic fields. Two perpetual magnets were applied to the cultured SH-SY5Y human neuronal cell, and the gene expression profiles were evaluated by using human mRNA microarray targeting 30968 genes. Results showed that the expressions of 827-known genes were altered in response to the magnetic force. Among them, 112 genes showed significant changes (>2-fold changes); 44 genes were up-regulated and 68 genes were down-regulated. Among the upregulated genes, we further confirmed the increased expressions of synapsin III and chloride channel-2 by using RT-PCR and immunocytochemistry. These results suggest that static magnetic fields influence neuronal-and biological-related gene expression profiles in human neuronal cells.
