A combined proteomic and targeted analysis unravels new toxic mechanisms for zinc oxide nanoparticles in macrophages

The cellular responses of the J774 macrophage cell line to zinc oxide and zirconium oxide nanoparticles have been studied by a comparative quantitative, protein level based proteomic approach. The most prominent results have been validated by targeted approaches. These approaches have been carried out under culture conditions that stimulate mildly the aryl hydrocarbon receptor, thereby mimicking conditions that can be encountered in vivo in...
