Clastogenic effects of acrylamide in mouse bone marrow cells.
Acrylamide, known to induce dominant-lethal mutations (Shelby et al., 1986; Smith et al., 1986) and heritable translocations (Shelby et al., 1987) in rodent germ cells, was hitherto a questionable clastogen in rodent bone marrow (Shiraishi, 1978). Therefore, it was tested for chromosomal aberrations in mouse bone marrow cells, spermatogonia and by the micronucleus test. The intraperitoneally injected doses ranged from 50 to 150 mg/kg. In the chromosomal bone marrow test and the micronucleus assay positive results were obtained with acrylamide, and in the latter test the effect increased linearly with dose. Chromosomal aberrations were not induced in differentiating spermatogonia by the acute acrylamide treatment. Cisplatin was used as a positive control and gave the expected positive response in all 3 tests. The present results demonstrate that acrylamide is no exception among clastogens. It breaks chromosomes not only in mammalian germ cells but also in somatic cells.[1]References
