Abstract
Sodium arsenite and sodium arsenate were observed to induce morphological transformation of Syrian hamster embryo cells in a dose-dependent manner. A linear dose-dependence with a slope of ∼1 was observed with both compounds when the data were plotted on a log-log graph. The trivalent sodium arsenite was > 10-fold more potent than the pentavalent sodium arsenate. The compounds also exhibited toxicity; however, transformation was observed at non-toxic as well as toxic doses. At low doses, enhanced colony-forming efficiency of the cells was observed. To understand the mechanism of arsenic-induced transformation, the genetic effects of the two arsenicals were examined over the same doses that induced transformation. No arsenic-induced gene mutations were detected at two genetic loci. However, cell transformation and cytogenetic effects, including endoreduplication, chromosome aberrations, and sister chromatid exchanges were induced by the arsenicals with similar dose-responses. These results support a possible role for chromosomal changes in arsenic-induced transformation.This publication has 8 references indexed in Scilit:
