| Abstract: | Nanoplastics (NPLs) are contaminants with the potential to threat human health. Inhalation is a major route for NPLs exposure, as evidenced by their detection in human lungs, where polyethylene terephthalate (PET) has been detected as one of the most abundant. However, the potential harmful effects of the accumulation of these particles are still largely unknown, as chronic effects have not yet been studied. To study these long-term effects, BEAS-2B bronchial cell line was exposed to PET-NPLs for 30 weeks. Genotoxicity, phenotypic hallmarks of carcinogenicity and a panel of genes related with cancer progression were studied and compared between three different time points: 24h, 15 and 30 weeks . Increased genotoxic damage, anchorage independent growth ability and invasive potential was observed after 30 weeks of exposure. Gene expression analysis results were in concordance with an incremented response in the amount of DEGs over time. GSEA disclosed EMT and RAS signaling pathways as candidates. Overall, the results suggest that long-term exposures to PET-NPLs exhibit a carcinogenic potential in BEAS-2B cells. |
