Research Laboratories, Schering Aktiengesellschaft, 13342 Berlin, Germany 1 We are reporting investigations into the potential of the steroid hormones chlormadinone acetate (CMA), cyproterone acetate (CPA), ethinylestradiol (EE2) gestodene (GEST), megestrol acetate (MGA), norethis terone acetate (NET-Ac), estradiol (E 2), and progester one (P) to form DNA-adducts in rat liver in vivo. 2 Compound-related DNA-adduct spots were detected in male and female rat liver following CMA, CPA, and MGA using the 32P-postlabeling-technique. Substance- specific DNA-adducts were also observed in male rats after administration of E2. The other compounds showed no DNA-adduct formation. After treatment with CMA, CPA or MGA, the relative adduct labeling (RAL) differed sex- and substance-specifically.
Key Words: sex steroid hormones DNA-adduct 32P-postlabeling assay
