Figure 10From: Evaluation of cytotoxic, genotoxic and inflammatory responses of nanoparticles from photocopiers in three human cell lines Gene expression change in THP-1 cells after 6 hr exposure of 5 μg/mL nanoparticles collected from photocopiers. RT-qPCR indicated gene alteration by fold change (Y-axis), *compared to untreated control, *p < 0.05. n = 3.Back to article page
