Chemical carcinogens can be classified into two categories (i.e. mutagenic and non-mutagenic) on the basis of positive or negative evidence of DNA damage, mutagenicity or chromosomal aberrations in short-term test systems. Evidence indicates that carcinogenic peroxisome proliferators are negative in short-term test systems. This paper outlines approaches which may be useful in identifying a chemical carcinogen without mutagenic activity. It is conceivable that an alteration in DNA, if essential for initiation of neoplasia, may be mediated indirectly by the biological effects of nonmutagenic carcinogens.
