Even for these known carcinogens there are sizable variations in species response; the most striking occurs with AAF where at least 15 species have been tested (2). With this compound the guinea pig, cotton rat,

Aflatoxin B1: Correlations of Patterns of Metabolism and DNA Modification with Biological Effects,latoxins and other chemical carcinogens are mediated by activation through metabolism by one or more of the mixed-function oxidases and subsequent covalent modification of cellular macromolecules (1). Experimental evidence indicates that AFB.-2,3-oxide is the ultimate reactive metabolite (2,3). It i

N-Nitroso compounds, on the other hand, are commonly carcinogenic in all species examined, but induce tumors of different cell types and in different organs from one species to the next. This variability is particularly true of nitrosamines, whose organ and species specificity are prob

Organ Specificity and Interspecies Differences in Carcinogenesis by Metabolism-Independent Alkylaticlude some of the most potent known mutagens and carcinogens. Their conversion to reactive intermediates requires no enzyme-mediated catalysis, and in this respect these compounds differ from the great majority of organic chemical carcinogens. Many of the direct-acting alkylating agents have been us

Chemical Carcinogenesis Studies in Nonhuman Primates, man, and the problem of risk assessment for humans remains largely unsolved. Extrapolation of rodent carcinogenesis data to man is particularly difficult because of known species differences in metabolic pathways (both activation and detoxification), involving potentially carcinogenic chemicals.

Tumor promoters cause or allow the expression of the latent tumor phenotype induced in some cells by limited doses of carcinogens. Both chemical and physical stimuli can act as tumor promoters.
