Abstract

The presence of glucocorticoid receptors (GR) in rat liver nuclei over a 24 h time period following hyperthermic stress at 41°C was immunocytologically studied using unfixed nuclear smears. Liver nuclei in unstressed animals were found to be immunonegative for GR. However, intense GR immunopositivity followed by a subsequent gradual decrease in receptor levels was observed in the nuclei of test animals during the first 2 h after stress. This stress-related increase in the receptor nuclear level was greater than the increase seen after dexamethasone administration. These results suggest that hyperthermic stress could potentiate the hormonal stimulation of receptor nuclear translocation.
