title: Retinoic acid and butylated hydroxyanisole inhibit promoter-enhanced transformation in vitro.
abstract: The inhibitory effects of some antipromoters were studied using a two-stage transformation assay system in vitro with 3-methylcholanthrene (3-MC)-initiation and 12-O-tetradecanoylphorbol-13-acetate (TPA)-promotion in BALB 3T3 cells. Butylated hydroxyanisole (BHA), a phenolic antioxidant, inhibited TPA-enhanced transformation in a dose-dependent manner, but butylated hydroxytoluene (BHT) did not. Among the three antipromoters tested, retinoic acid (RA) was the most effective inhibitor.
