Researchers used lipidomics and transcriptomics to examine how polystyrene microplastic exposure affects liver lipid metabolism in mice over eight weeks. The study found that while body weight and serum lipid levels were not significantly affected, microplastics caused impaired glucose metabolism and specific changes in hepatic lipid profiles, revealing subtle but measurable disruptions to liver function.
Impacts of polypropylene microplastics on lipid profiles of mouse liver uncovered by lipidomics analysis and Raman spectroscopy
Researchers found that polypropylene microplastics accumulated in mouse liver tissue and caused significant changes to lipid metabolism, even without obvious outward health symptoms. Advanced analysis revealed altered fat profiles and lipid droplet buildup in the liver. This study suggests that microplastic exposure could quietly disrupt liver fat processing, which is relevant to understanding long-term metabolic health effects in mammals.
Untargeted metabolomics and transcriptomics joint analysis of the effects of polystyrene nanoplastics on lipid metabolism in the mouse liver
Mice exposed to polystyrene nanoplastics for 12 weeks gained weight without eating more and showed increased cholesterol levels and fat accumulation in their livers. Gene and metabolite analysis revealed that the nanoplastics disrupted fat metabolism pathways in the liver, essentially reprogramming how the body processes and stores fat. These findings suggest that nanoplastic exposure could be a hidden factor contributing to obesity and fatty liver disease in humans.
[The effect and mechanism of exposure to polystyrene nanoplastics on lipid metabolism in mice liver].
Researchers exposed mice to 20 nm polystyrene nanoplastics and investigated the effects on hepatic lipid metabolism using multi-omics approaches. Nanoplastic exposure disrupted lipid metabolic pathways in the liver, causing significant changes in lipid accumulation and related gene expression, suggesting a mechanism by which nanoplastic ingestion may contribute to metabolic disorders.

The study found that microplastic exposure disrupted hepatic lipid metabolism pathways and caused liver oxidative stress in birds.
