As described earlier in Chapter 2, B[a]P is metabolized mainly to the 7R 7.8-transdihvdrodiol. However, both enantiomers are further epoxidized on the lower face of the molecule. Thus, while the 7R enantiomer forms mainly the anti-diol epoxide, the 7S enantiomer forms mainly svn-diol epoxide. In some systems, such as human colon (138) or hamster embryo cells (139), significant quantities of svn-diol epoxide adducts are found, including adducts... 

Aniline transformed the Balb/3T3 mouse cell line at doses of 0.8 to 100 /dose-response effect), but not the Syrian hamster embryo cells (Dunkel et al. 1981). Results were negative in DNA damage assays in Escherichia coli (Mamber et al. 1983) and Bacillus subtilis (McCarroll et al. 1981).

Water-soluble nickel salts enter the cells with relative ease but are less effective than crystalline particulates in the cell transformation assay, when using hamster cells [429, 430]. However, an enhancement of viral transformation of cells has been found [431, 432], In addition, a synergistic effect of cigarette smoke extracts, benzo[a]pyrene and nickel sulphate on the morphological transformation of hamster embryo cells has also been obtained [433], It was suggested that nickel salts are more potent as promoters than they are as initiators [434],...

The interest in bile acids as potential carcinogens was subject to investigation as early as 1940 when Cook et al. reported in Nature that repeated injection of deoxycholic acid into the flanks of mice could induce tumour formation in mice." Furthermore, Kelsey and Pienta showed that treatment of hamster embryo cells with lithocholic acid could cause cell transformation. ...

Acetamide was mutagenic in Escherichia coli and Salmonella typhimurium-, this effect was independent of dose. Acetamide produced morphological transformation in Syrian hamster embryo cells in the absence of metabolic activation. However, acetamide did not induce reversions in several Salmonella typhimurium strains. ...

In one of two studies, di(2-ethylhexyl) phthalate induced a small increase in sister chromatid exchange frequencies in Chinese hamster ovary cells cultured without but not with exogenous metabolic activation. In other studies conducted only without metabolic activation, it caused no increase in sister chromatid exchanges in either Chinese hamster Don cells or rat liver RL4 cells. Di(2-ethylhexyl) phthalate did not induce micronuclei in Chinese hamster ovary cells or in cultured rat hepatocytes, whereas the induction of micronuclei by di(2-ethylhexyl) phthalate in Syrian hamster embryo cells has been reported. 

Chromosomal aberrations were not induced by di(2-ethylhexyl) phthalate in any of eight studies in various types of cultured cells in the absence of metabolic activation. Only three of these studies for chromosomal aberrations included an exogenous metabolic activation system. Of these, one, using Syrian hamster embryo cells, found an increase in aberration frequency. Weak effects were detected for the induction of aneuploidy and mitotic division aberrations in Chinese hamster lung cells. 

RLV/Fischer rat assay without the addition of an exogenous metabolic activation system. In a single study, mouse JB6 epidermal cells were transformed by di(2-ethyl-hexyl) phthalate without activation and in one of two studies a weak response was reported in the CSHIOT A cell transformation assay with di(2-ethylhexyl) phthalate in either the absence or presence of exogenous metabolic activation. BALB/c-3T3 cells were not transformed by di(2-ethylhexyl) phthalate with or without metabolic activation. Di(2-ethylhexyl) phthalate inhibited gap-junctional intercellular communication in Chinese hamster V79 cells in six of seven studies, but not in one study of liver cells of cynomolgus monkeys in vivo. Di(2-ethylhexyl) phthalate treatment of Syrian hamster embryo cells in a two-stage exposure with 12-O-tetradecanoylphorbol 13-acetate resulted in superinduction of ornithine decarboxylase, an early event in morphological transformation no effect was seen after a one-stage treatment with di(2-ethylhexyl) phthalate alone. 

Unscheduled DNA synthesis was not induced in either mouse or hirman primary hepatocyte cultures with mono(2-ethylhexyl) phthalate, and neither this metabolite nor 2-ethylhexanol induced mutations in mouse lymphoma cells in vitro. Mono(2-ethyl-hexyl) phthalate induced sister-chromatid exchange in Chinese hamster V79 cells and chromosomal aberrations in Syrian hamster embryo cells. It also induced transformation in Syrian hamster embryo cells, but not in mouse C3H10T /2 cells. Gap-junctional intercellular communication was inhibited by mono(2-ethylhexyl) phthalate in Syrian hamster embryo cells and in Chinese hamster V79 cells. As reported in an abstract (Baker et al., 1996), this function was also inhibited in rat and mouse hepatocytes, but not in Syrian hamster or human hepatocytes.
