Evaluating Carcinogenic Risks,ly related to the way many defend their articles of faith than to the way in which data are evaluated objectively. Nevertheless, in the selection of hazards for evaluation, public opinion will and should be influential.

Nongenotoxic Chemical Carcinogens: Evidence for Multiple Mechanisms,hanisms, such as by generating oxidative products which can damage DNA. This paper will focus on the minimalist definition of mutagenicity and how it may aid in identifying and understanding chemicals which operate through nonmutagenic mechanisms to induce cancer.

Nongenotoxic Carcinogenesis in the Liver, is not only a problem in rodents, and assessment of human health risks is urgently required. For this purpose we need to know the relevant .biological effects of these agents in rodent and human liver as well as the mechanisms underlying carcinogenesis.

The Role of Genotoxic and Nongenotoxic Agents in Multistage Carcinogenesis of Mouse Skin,n attempts to enter a suicide pathway, which is a frequent primary response to DNA-damaging agents. All of this must, of course, take place within the correct target cell, i.e., either a stem cell with a naturally extended lifespan, or a more committed cell which can acquire an extended lifespan upon exposure to a carcinogenic stimulus.

Nongenotoxic Chemical Carcinogens: Evidence for Multiple Mechanisms,For the purpose of this discussion a minimalist definition of a genotoxic carcinogen will be used. This definition includes chemicals which possess one of the structural alerts, generally indicative of electrophilic potential (Miller and Miller 1977) defined by Ashby (1985; Tennant and Ashby 1991),

Oxidative Damage and Carcinogenesis,nts are ubiquitous in our natural environment but they can also be formed in the tissue by endogenous cellular mechanisms (Cerutti 1985; Kozumbo et al. 1985; Cerutti and Trump 1991). Oxidants can introduce structural damage to DNA, leading to chromosomal aberrations and point mutations. Point mutati
