title: Effect of antioxidants on mutagenesis induced by DMBA in human cells.
abstract: The effect of vitamin A palmitate (VAP), vitamin A acetate (VAA), 2,3-tert-butyl-4-hydroxyanisole, and 2,6-di-tert-butyl-p-cresol (BHT) on mutagenesis induced by 7,12-dime-thylbenz[a]anthracene (DMBA) was examined in a human epithelial-like cell line. Cultures were exposed to DMBA with or without the antioxidant compound, and mutation frequencies were determined by selection against diphtheria toxin. A clear inhibition of mutagenesis was observed particularly with VAA and BHT.
