Ardicli et al. investigate the effects of the widely used polyethylene terephthalate polymer, known as #PET, which is commonly used for water and beverage bottles and packaged foods, on human intestinal cell cultures at various concentrations and particle size range. At high doses, transepithelial electrical resistance measurements and the MTT cell viability assay indicate epithelial barrier dysfunction and oxidative stress, respectively. Transcriptomic analysis supported the dose-dependent physiological and proteomic changes. Upregulated genes corresponded to pathways related to apoptosis, endoplasmic reticulum stress and oxidative stress responses. These findings highlight the toxic effects of micro and nanoplastic ingestion on human health.
