Abstract

Benzo[a]pyrene diolepoxide (BPDE) is thougth to be the major mutagenic and carcinogenic intermediate in benzo[a]pyrene metabolism in mammalian cells. In order to test the mutagenic specificity of this compound in mammalian cells, we have used the PZ189 shuttle vector system to identify and analyze point mutations induced when DNA treated in vitro with BPDE is replicated in monkey cells. We find that point mutations occur almost exclusively at G·C base pairs; G·C→T·A and G·C→C·G transversions and single base pair deletions occur most frequently. This pattern is consistent with the known preferential covalent binding of BPDE to redisue.
