Researchers used computational and laboratory methods to investigate how polyethylene terephthalate microplastics may promote immune evasion in breast cancer cells. They identified four immune-related genes that appear to be affected by microplastic exposure, potentially allowing cancer cells to avoid immune detection. The study suggests that microplastic contamination could influence cancer progression through immune system disruption, though further research is needed.
Microplastics promote chemoresistance by mediating lipid metabolism and suppressing pyroptosis in colorectal cancer
This study found that microplastics can make colorectal cancer cells more resistant to chemotherapy drugs. Cancer cells absorb microplastics through a protein called clathrin, which triggers increased fat absorption and suppresses a cell death pathway that drugs normally rely on. These findings suggest that microplastic accumulation in the gut could potentially interfere with cancer treatment effectiveness.

Researchers used an integrative computational approach combining cross-species transcriptomics, network toxicology, and molecular docking to investigate potential links between polystyrene microplastic exposure and childhood obesity. They identified shared gene targets involved in lipid metabolism and insulin signaling pathways, with molecular docking confirming stable binding between microplastic compounds and key metabolic proteins. The findings provide a preliminary molecular hypothesis suggesting microplastics could disrupt metabolic processes relevant to obesity.
Microplastics: An emerging environmental risk factor for gut microbiota dysbiosis and cancer development?
This review examines how microplastics may disrupt the gut microbiome and immune system in ways that could promote cancer development.
