Exposure to polystyrene nanoparticles leads to dysfunction in DNA repair mechanisms in Caco-2 cells
Summary
Researchers found that exposing intestinal cells (Caco-2) to polystyrene nanoplastics impaired DNA repair mechanisms even at doses that didn't kill the cells, raising concern that nanoplastic exposure could lead to genetic instability and long-term health risks over time.
This study highlights the sublethal effects of nanoplastics on intestinal barrier cells. It underscores the possible risks of exposure to these environmental contaminants, which can lead to genome instability and other long-term health consequences.

Nanoplastics as a potential environmental health factor: effects of polystyrene nanoparticles on human intestinal epithelial Caco-2 cells
Researchers tested how polystyrene nanoparticles interact with human intestinal cells in the lab. They found that the nanoparticles were readily taken up by the cells in a concentration-dependent manner, but no significant toxic effects were observed under the conditions tested. The study suggests that while nanoplastics can enter gut cells, their short-term toxicity at the tested levels appears limited.
Polystyrene nanoparticles induce DNA damage and apoptosis in HeLa cells
Researchers exposed human HeLa cells to polystyrene nanoplastics — particles smaller than 100 nm — and found that even short exposures at low concentrations caused DNA damage, abnormal cell division, and signs of cell death including apoptosis and necrosis. The results suggest nanoplastics can directly damage human cell DNA, raising concerns about the health implications of everyday nanoplastic exposure.
Tiny plastic, big trouble: how polystyrene nanoparticles impact DNA-damage repair deficient cervical cancer cells
Researchers investigated how polystyrene nanoparticles affect cervical cancer cells with DNA-damage repair deficiencies. The study found that exposure to uniformly sized polystyrene nanoparticles had cytotoxic effects on cancer cells, suggesting that microplastic exposure may have particular consequences for cells already compromised in their ability to repair DNA damage.
Long-Term Effects of Polystyrene Nanoplastics in Human Intestinal Caco-2 Cells
Researchers exposed human intestinal cells to polystyrene nanoplastics over an extended period to simulate chronic dietary exposure. They found that long-term exposure at low concentrations caused subtle but persistent changes in cell function, including altered gene expression and increased oxidative stress markers. The study highlights that the health effects of nanoplastics may build up gradually over time, underscoring the importance of studying chronic rather than just short-term exposure.
