Inducation of chromosomal aberrations in cultured mammalian cells by nickel compounds.

Abstract

The effects of 4 Ni compounds, nickel chloride, nickel acetate, potassium cyanonickelate, and nickel sulfide were studied in a line of mammary carcinoma cells from the C3H mouse. All 4 were easily taken up by the cells and reacted with protein, RNA, and possibly DNA. Measurements of leucine, uridine, and thymidine uptake during exposure showed that the syntheses of protein and DNA were more sensitive than RNA. Chromosomal aberrations were observed during the recovery period following the end of the treament with Ni. The implications of these results were discussed with respect to the carcinogenicity of the compounds and to the recommended protocols for mutagenicity testing by chromosomal aberrations.
