Dear Sir,
In a recent issue of the Journal, Yang and Duerksen-Hughes present a new in vitro approach for identifying genotoxic carcinogens. In this study they used p53 induction in vitro as an indicator of genotoxic damage. The authors suggest that this endpoint could be used as an effective tool for identifying environmental carcinogens.
In our opinion, p53 induction has clear weaknesses as an endpoint for in vitro genotoxicity testing. It is induced by many types
