title: Chemical transformation of human revertant cells induced by murine sarcoma virus.
abstract: A human revertant cell line, derived from non-producer human osteosarcoma cells (NP/KHOS) induced by Kirsten murine sarcoma virus, was treated in vitro with various levels of polycyclic aromatic hydrocarbons (3-methylcholanthrene, 7,12-dimethylbenz(alpha)anthracene, and benzo(alpha)pyrene [BP] or dimethyl sulfoxide (control). Cells treated only with 3-methylcholanthrene and 7,12-dimethylbenz(alpha)anthracene underwent morphological alteration in vitro, and produced tumors when injected into NIH nude mice. These human revertant cells may be a useful in vitro tool in screening for the potential chemical carcinogens in human cell systems.
