1 We have tested the hypothesis that antidepressants affect the expression of the glucocorticoid receptor gene, by looking at glucocorticoid receptor gene promoter activity, glucocorticoid receptor mRNA levels, and glucocorticoid-binding activity after treatment of different cell lines with desipramine. Desipramine nuclear receptor subfamily 3, group C, member 1 Mus musculus
2 Treatment of LTK- cells or Neuro 2A cells with desipramine produced a 50-200% increase in chloramphenicol acetyltransferase activity transcribed from a 2.7-kilobase glucocorticoid receptor gene promoter region. Desipramine nuclear receptor subfamily 3, group C, member 1 Mus musculus
3 In cell lines derived from both neuronal and non-neuronal sources, glucocorticoid receptor mRNA concentration doubled after desipramine treatment, and this was associated with a 2-fold higher functional glucocorticoid binding capacity and increased glucocorticoid sensitivity, as measured with the reporter plasmid pMMTVCAT. Desipramine nuclear receptor subfamily 3, group C, member 1 Mus musculus
