Synergistic Effect of Metal Oxide Nanoparticles on Cell Viability and Activation of MAP Kinases and NFκB
AbstractIn recent years, there has been an increase in the production of several types of nanoparticles (Nps) for different purposes. Several studies have been performed to analyse the toxicity induced by some of these individual Nps, but data are scarce on the potential hazards or beneficial effects induced by a range of nanomaterials in the same environment. The purpose of the study described here was to evaluate the toxicological effects induced by in vitro exposure of human cells to ZnO Nps in combination with different concentrations of other metal oxide Nps (Al2O3, CeO2, TiO2 and Y2O3). The results indicate that the presence of these Nps has synergistic or antagonistic effects on the cell death induced by ZnO Nps, with a quite marked beneficial effect observed when high concentrations of Nps were tested. Moreover, analysis by Western blot of the main components of the intracellular activation routes (MAPKs and NFκB) again showed that the presence of other Nps can affect cell activation. In conclusion, the presence of several Nps in the same environment modifies the functional activity of one individual Np. Further studies are required in order to elucidate the effects induced by combinations of nanomaterials. View Full-Text
