The role of partial hepatectomy and of promoters in the formation of tumors in non-target tissues of trans-4-acetylaminostilbene in rats.
    Carcinogenesis, 1983, Volume: 4, Issue:12

    After repeated administration of trans-4-acetylaminostilbene to rats, DNA-bound metabolites accumulate to the greatest extent in liver and kidney, which are considered to be nontarget tissues for this carcinogen. To test whether the persistent DNA adducts represent procarcinogenic lesions, an initiation-promotion experiment was carried out using trans-4-acetylaminostilbene as an initiator and phenobarbital, DDT and diethylstilbestrol as promoters. In addition, partial hepatectomy was performed in some groups. Partial hepatectomy alone or in combination with promoters led to the formation of preneoplastic enzyme deficient foci, hyperplastic nodules and hepatoma in great yields. In addition, mammary tumors were observed with diethylstilbestrol promotion. The results support our proposal that aminostilbene derivatives produce procarcinogenic DNA-lesions in many, if not all, tissues and that secondary factors determine when and where tumors arise.
