In female rats, the incorporation of sodium C14-formate into mammary gland RNA decreases immediately after a singlefeeding of 20 milligrams of 7,12-dimethylbenz[a] anthracene. In males, there is a gradual increase in the incorporation. In castrated rats, the decrease or increase of C14-formate incorporation is dependent on the presence of estrogen or androgen, respectively.
