ClearIntegrative network toxicology and molecular docking preliminarily explore the potential role of polystyrene microplastics in childhood obesity
Researchers used computational methods including network toxicology, machine learning, and molecular docking to explore how polystyrene microplastics might contribute to childhood obesity.

Exposure to a mixture of micro- and nanoplastics increased fat production and impaired the body's ability to use insulin and process sugar in both cell and zebrafish experiments. The plastic mixture triggered inflammation, boosted fat-storing genes, and suppressed insulin signaling pathways. These findings suggest that microplastic exposure could contribute to obesity and type 2 diabetes.
