Graphene oxide (GO) has attracted enormous interests due to its extraordinary properties. Recent studies have confirmed the cytotoxicity of GO, we further investigate its mutagenic potential in this study. The results showed that GO interfered with DNA replication and induced mutagenesis at molecular level. GO treatments at concentrations of 10 and 100 μg/mL altered gene expression patterns at cellular level, and 101 differentially expressed genes mediated DNA-damage control, cell apoptosis, cell cycle, and metabolism. Intravenous injection of GO at 4 mg/kg for 5 consecutive days clearly induced formation of micronucleated polychromic erythrocytes in mice, and its mutagenesis potential appeared to be comparable to cyclophosphamide, a classic mutagen. In conclusion, GO can induce mutagenesis both in vitro and in vivo, thus extra consideration is required for its biomedical applications.
