title: [Induction of thymidine kinase synthesis by 5-androstene-3 beta,17 beta-diol in the uterus of the immature rat].
abstract: In uteri from immature female rats, thymidine kinase activity was largely increased by administration of 5-androstene-3 beta, 17 beta-diol. Kinetic studies showed that the enzyme activity reached its maximum level 30 h after hormone administration. That increase in thymidine kinase activity was dose-dependent and could be related to the synthesis of new molecules of enzyme. Moreover, it was exclusively observed in target-organs for estrogens. It was concluded that 5-androstene-3 beta, 17 beta-diol which results from the metabolism of dehydroepiandrosterone had estrogen-like properties with regard to the induction of thymidine kinase.
