Abstract

Vinyl carbamate (VC) is a suspect metabolic intermediate in ethyl carbamate (EC) carcinogenesis. In the present studies, EC and VC were evaluated for their relative abilities to induce adenomas and sister chromatid exchanges (SCEs) in lung cells of A/J, C3HeB/FeJ, and C57BL/6J strain mice. For both end points, animals were administered a single i.p. injection of the test chemical. Percentage of mice with adenomas and number of adenomas per mouse were compared among the three strains 24 weeks following exposure to EC or VC. Although the relative order of strain sensitivity was the same for both chemicals: A/J greater than C57BL/6J greater than C3HeB/FeJ, VC was much more potent than EC. For SCE analysis of primary lung cells cultured from treated animals, EC and VC showed potency differences similar to those observed for tumorigenesis. All three mouse strains revealed significant dose-dependent increases in SCE frequency. However, there was no strain specificity for this effect. SCE persistence over time was also compared in treated A/J and C57BL/6J mice. Although EC- and VC-induced SCE frequencies declined over a 2-week observation period, again, there was no strain specificity for this effect. VC was also tested for enhancement of SA7 virus transformation of Syrian hamster embryo cells. Significant concentration-dependent increases in cell transformation frequency were observed.
