  • Title: Formation of 7,12-dimethylbenz[alpha] anthracene-DNA adducts in 7,8-benzoflavone-treated hamster embryo cells.
    Author: Baird WM, Diamond L.
    Journal: Chem Biol Interact; 1978 Feb; 20(2):181-90. PubMed ID: 417810.
    Abstract:
    Pretreatment of secondary cultures of Syrian hamster embryo cells with 7,8-benzoflavone (7,8-BF) inhibited both the metabolism of 7,12-dimethylbenz[alpha] anthracene (DMBA) and the formation of DMBA-DNA adducts. The DMBA-deoxyribonucleoside adducts from 7,8-BF-treated cultures had the same elution profiles on Sephadex LH-20 columns as those from cultures exposed to DMBA alone, but 7,8-BF-treated cultures contained smaller amounts of DMBA-DNA adducts per mg DNA. As the concentration of 7,8-BF was increased, the decrease in the amount of DMBA-DNA adducts per mg DNA was logarithmic with respect to the decrease in the amount of DMBA metabolized. The results suggest that more than one metabolic step is required for the binding of DMBA to DNA in hamster embryo cells.
