Title: Estrogen- and progestin-receptor complexes and their interaction with rat liver cell nuclei during ontogenesis

Abstract

Steroid-receptor complexes (SRC) of estrogens and progestins have been isolated from the rat liver and purified 1500-2000-fold. Both in the state of the initial cytosol and purified 2000-fold, the SRC were characterized by gel filtration on Sephadex G-100 and by DEAE-cellulose chromatography. The purified SRC from the rat liver were used for binding to isolated liver cell nuclei from rats of different ages (1.5 months, 6 months, 12 months, 24 months). The maximum binding of SRC of progestins and estrogens from the rat liver is observed with homologous nuclei of 1.5-month-old rats. With age the binding of SRC by the nuclei decreases progressively and reaches a minimum by 24 months. The detected differences in the binding of SRC by the nuclei of cells of animals of different ages, in their opinion, may lie at the basis of changes in the functioning of the organism under the influence of hormones at different stages of ontogenesis.
