Cis-platinum(II) diamine dichloride causes mutation, transformation, and sister-chromatid exchanges in cultured...

The anti-tumor agent cis-platinum(II) diamine dichloride caused dose-dependent toxicity in V79 Chinese hamster cells and in secondary Syrian hamster embryo cells. Chromosome aberrations were induced and positive dose--response relationships were observed for induction of sister-chromatid exchanges and 6-thioguanine-resistant mutations in V79 cells and morphologic transformation of secondary Syrian hamster embryo cells. The findings suggest that this chemical is a potential human carcinogen.
