Rank order of sarcoma susceptibility among mouse strains reverses with low concentrations of carcinogen

Science. 1979 Apr 20;204(4390):309-10. doi: 10.1126/science.432644.

Abstract

Ten mouse strains in which aryl hydrocarbon hydroxylase can be induced, or F1 hybrids of these strains, were ranked according to their sarcoma susceptibility when exposed to a high concentration (5 percent) of the chemical carcinogen 3-methylcholanthrene. This rank order was reversed when the concentration of 3-methylcholanthrene was reduced to 0.05 percent.
