Genetic effects from exposure to hazardous agents.

Environ. Health Perspect. 101, 263-267 (1993)
Mammalian germ cell stages exhibit differences in DNA synthesis activity, capability to repair DNA damage, and chromosome-associated proteins. The sensitivity to mutation induction may be influenced by such factors as the accessibility of DNA to chemical mutagens, the interval between DNA damage induction and the next round of DNA replication, and the repair of DNA damage. Such qualitative and quantitative differences indicate the complexities of mutation induction in vivo and emphasize that no single in vitro test system can adequately represent the in vivo situation. Therefore, germ-cell mutagenesis in humans can most adequately be represented by an vivo mammalian germ-cell test system. Information regarding the mechanisms of mutation induction in germ cells of the mouse, appropriate mutation test systems available in the mouse, as well as principles of chemical mutagenesis in the mouse and their implications for an adequate human genetic risk estimation will be discussed.
