Nanotoxicity assessment of titanium dioxide (TiO2) under oxidative stress (OS) conditions is a novel field. Compared with nanomaterials (NMs) exposure only, OS conditions and nano-TiO2 synergistically reduced BRL-3A cell viabilities and resulted in the rapid G0/G1 to S phase transition and G2/M arrest. Interactions between OS conditions and nano-TiO2 induced obvious pathological changes in rat livers and enhanced the activities of liver damage biomarkers.
