[Estrogen- and progestin-receptor complexes and their interactions with rat liver cell nuclei in ontogenesis].
Steroid-receptor complexes (SRC) of estrogen and progestin were isolated from rat liver and purified 1500-2000-fold. The SRC within the composition of cytosol and purified 2000-fold were characterized by gel filtration of Sephadex G-100 and by DEAE-cellulose chromatography. The purified SRC from rat liver were bound to isolated liver cell nuclei of rats of various age (1.5, 6, 12 and 24 month-old). The maximal binding of progestin and estrogen SRC from rat liver was observed in homologous nuclei of 1.5-month-old animals. The binding of SRC by the nuclei decreased progressively with age, reaching its minimum in 24-month-old rats. The observed differences in the SRC binding by cell nuclei of experimental animals may be the cause of functional changes at various stages of ontogenesis.
