tokens: In SN-48 neuronal cells that express MR , GR , and 5-HT1A receptors , deletion or inactivation of the nGRE ( negative GRE ) eliminated negative regulation of the rat 5-HT1A or heterologous promoters by corticosteroids , whereas its inclusion conferred corticosteroid induced inhibition to a heterologous promoter .
