title: Mutagenicity and carcinogenicity of 8-MOP/UVA in cell cultures.
abstract: HGPRT-deficient mutants of chinese hamster cells and human skin fibroblasts are selected with 6-thioguanine after treatment with the combination 8-MOP and UVA. Calculation based on this study indicate that 1.7 X 10(-5) mutants will be induced in the epidermis per session of PUVA therapy. Induction of cell-transformation was observed in C3H and 3T3 mouse cells.
