The RNA polymerase activity of the purified nuclei from the prostate of castrated rats was measured shortly after the subcutaneous injection of testosterone propionate to the animals. A significant enhancement of RNA polymerase activity was demonstrable within a few hours after the single injection of the androgen if the enzyme activity was measured in a reaction mixture of a relatively low ionic strength. Under the same conditions, RNA polymerase activity of thymus or liver nuclei of orchiectomized rats was not increased by the administration of testosterone to the animals. (Endocrinology77: 763, 1965)
