In this study, photochromic PVP-stabilized tungsten oxide nanoparticles (WO3-x NPs) were shown to exhibit a dose-dependent cytotoxic effect on mouse fibroblasts in vitro. WO3-x NPs reduce viability and proliferative activity of the cells via induction of intracellular oxidative stress leading to apoptosis and cell death. WO3-x NPs modulate the mRNA expression of a wide range of genes responsible for oxidative stress and the cell redox-system.
Keywords: tungsten oxide nanoparticles, cytotoxicity, apoptosis, fibroblasts.
