Cytotoxic and genotoxic effects of cadmium sulfide nanoparticles
Cadmium compounds are highly toxic substances characterized by mutagenic, genotoxic and carcinogenic effects, and having high cumulative properties. Application of cadmium nanoparticles (NPs) in medicine stimulates the study of their mechanism of action at the cellular level and at the level of orga...

The aim of the study was to compare the features of cytotoxic and genotoxic effects of cadmium sulfide (CdS) NPs of different sizes on cell cultures of different histogenesis with those of cadmium chloride (CdCl2). Materials and Methods: In this work, we used cadmium compounds in the nanoform: NPs CdS of 4–6 nm and of 9–11 nm in size; and in the ionic form: CdCl2. The studies were conducted in vitro in cell lines — IMR-32, НEК-293 and MАEC.

We evaluated the genotoxic effect of the substances studied in vitro using DNA comet assay in alkaline conditions. Results: CdS NPs and CdCl2 demonstrated pronounced dose-dependent cytotoxic effect in MАEC, НEК-293 and IMR-32 cell lines, by impairing membrane permeability, functioning of mitochondria and lysosomes, and inhibiting the function of protein synthesis. Cytotoxic effect of CdCl2 was the most pronounced, this effect of CdS NPs of 9–11 nm in size being the least pronounced. The comet DNA assay in alkaline conditions revealed a statistically significant increase in DNA comet index when exposed to CdCl2 and CdS NPs in comparison with the negative control, which indicates their genotoxic effect. CdS NPs of 4–6 nm in size showed a more pronounced effect in comparison with those of 9–11 nm in size.
