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 .
 GENE: MR; GENE: GR; GENE: 5 - HT1A receptors; GENE: rat 5 - HT1A
