title: [Association of [3H]-dexamethasone with cytoplasmic receptor proteins and their translocation into liver cell nuclei during aging].
abstract: Interaction of 3H-dexamethasone with cytoplasmic proteins was studied in male rat liver cells. With ageing of the animals concentration of high affinity and low affinity glucocorticoid receptors was decreased 2-fold as well as the corresponding reduction of nuclear uptake in the steroid-receptor complexes was found. A protein species was found in cytoplasm of aged rat hepatocytes, which bound 3H-dexamethasone with "extremely low" affinity and was not able to associate with the cell nuclei.
