Abstract

The genotoxic effects of acrylamide, a recently detected carcinogen, have been studied in the somatic (wing primordia) and germ cells of Drosophila melanogaster by the wing mosaic assay and the sex-linked recessive lethal test respectively. Larvae, 72 +/- 4 h old, were exposed to 6 different concentrations of acrylamide ranging between 0.25 mM and 5.0 mM in instant medium for 48 h. It is observed that acrylamide is both mutagenic and recombinogenic in the wing disc cells and induces sex-linked recessive lethals.

摘要

最近检测出的致癌物丙烯酰胺的遗传毒性效应,已分别通过翼镶嵌试验和性连锁隐性致死试验,在黑腹果蝇的体细胞(翅原基)和生殖细胞中进行了研究。将72 ± 4小时龄的幼虫在即时培养基中暴露于6种浓度范围在0.25 mM至5.0 mM之间的丙烯酰胺中48小时。观察到丙烯酰胺在翅盘细胞中具有致突变性和重组性,并能诱导性连锁隐性致死。
