AB  - Glucocorticoid hormones inhibit uridine incorporation into ribonucleic acid of thymocytes. The relationship between this effect and the binding to glucocorticoid receptors in mouse thymocytes was studied in parallel. The 27 different steroids examined could be classified as either agonists (e.g., dexamethasone, hydrocortisone, corticosterone), which bind to thymocytes and have an inhibitory effect on uridine incorporation; antagonists (e.g., 6α, 16α-dimethylprogesterone, progesterone), which bind to receptors without significant effect on uridine incorporation and which inhibit the biochemical effect of agonists; or inactive steroids (e.g., estradiol, cortisone), which neither bind nor have any effect on uridine incorporation. Combined evaluation in mouse thymocytes thus appears to be a useful tool in screening of steroids for glucocorticoid activity. ACKNOWLEDGMENTS The authors thank Mlle E.
