The oestrogen-stimulated synthesis of heterogeneous nuclear ribonucleic acid in the uterus of immature rats.
An early response to the administration of oestradiol-17beta to immature rats is the synthesis of uterine RNA of very high-molecular-weight. This RNA is shown to be heterogeneous nuclear RNA. Increased precursor incorporation into the heterogeneous nRNA is not confined to entities of precise molecular weight but appears to involve much of the size range of the species. These findings are discussed with respect to the mode of action of oestradiol.
