Size distribution of fullerenol nanoparticles in cell culture medium and their influence on antioxidative enzymes in Chinese hamster ovary cells

Abstract

Fullerenol (C-60(OH)(24)) nanoparticles (FNP) have a significant role in biomedical research due to their numerous biological activities, some of which have cytoprotective and anti-oxidative properties. The aim of this study was to measure distribution of fullerenol nanoparticles and zeta potential in cell medium RPMI 1640 with 10\% fetal bovine serum (FBS) and to investigate the influence of FNP on Chinese hamster ovary cells (CHO-K1) survival, as well as to determine the activity of three antioxidative enzymes: superoxide-dismutase, glutathione-reductase and glutathione-S-transferase in mitomycin C-treated cell line. Our investigation implies that FNP, as a strong antioxidant, influences the cellular redox state and enzyme activities and thus may reduce cell proliferation, which confirms that FNP could be exploited for its use as a cytoprotective agent.
