Abstract
The synthesis of total cellular as well as acid-soluble nuclear proteins and estrogen receptor is high in the uteri of young (22 weeks) and decreases to half in old (104 weeks) rats. Administration of estrogen induces the synthesis of these proteins significantly in young but shows no remarkable effect in old rats. Interestingly, a specific cytosolic protein of 45 kDa is stimulated about two-fold after estrogen injection in young but not in old rats. These findings further establish the reduced responsiveness of uterus to estrogen in old age.
