The expression of mRNA for GABAA receptor alpha 1-subunit in mouse cerebral cortical neurons in primary culture was examined using RNA blot analysis and ribonuclease protection assay following the treatment of neurons with muscimol, a selective agonist of GABAA receptor. The level of mRNA for GABAA receptor alpha 1-subunit showed a decrease in comparison with that in non-treated cells, whereas no changes in the level of beta-actin mRNA were noted under the same experimental conditions. This muscimol-induced reduction in GABAA receptor alpha 1-subunit mRNA was counteracted by the simultaneous exposure of neurons to both bicuculline, an antagonist of GABAA receptor, and muscimol. The expression of mRNA for GABAA receptor alpha 1-subunit also showed a decline by the treatment of cells with flunitrazepam alone, an agonist of benzodiazepine receptor, and this change was also abolished by the simultaneous exposure of cells to flunitrazepam and Ro15-1788, an antagonist for central benzodiazepine receptor. These results suggest that the continuous stimulation of cerebral GABAA receptor complex may induce the reduced expression of mRNA for the receptor complex.
