Previously, we have found glucocorticoids up-regulate norepinephrine (NE) transporter (NET) expression in vitro. However, the underlying transcriptional mechanism is poorly understood. In this study, the role of glucocorticoids on the transcriptional regulation of NET was investigated. Exposure of neuroblastoma SK-N-BE(2)M17 cells to dexamethasone (Dex) significantly increased NET mRNA and protein levels in a time- and dose-dependent manner. This effect was attenuated by glucocorticoid receptor… CONTINUE READING
