ClearLipidomics and transcriptomics insight into impacts of microplastics exposure on hepatic lipid metabolism in mice
Researchers used lipidomics and transcriptomics to examine how polystyrene microplastic exposure affects liver lipid metabolism in mice over eight weeks.

Researchers exposed rats to polystyrene microplastics over 6 and 12 months and used advanced lipid profiling to assess liver damage. They found that long-term exposure caused liver inflammation, fatty liver changes, and significant alterations in eight key lipid metabolites involved in fat processing. The study provides evidence that chronic microplastic exposure can disrupt liver lipid metabolism, raising concerns about long-term health effects.

Researchers investigated the effects of orally administered polystyrene microplastics on liver metabolism in normal and obese mice over eight weeks. They found that microplastic exposure altered lipid, glucose, and amino acid metabolism pathways in the liver and adipose tissues. The study suggests that microplastic ingestion may disrupt hepatic metabolic functions, with potentially different impacts depending on baseline metabolic health status.

Researchers exposed chickens to polystyrene nanoplastics through feed for 120 days and used metabolomics to assess the impact on liver health. They found significant liver damage, including increased lipid accumulation and elevated liver enzyme levels, along with disruption of 193 metabolites primarily related to lipid and amino acid metabolism. The study raises food safety concerns, suggesting that nanoplastic contamination in poultry feed could affect the quality and safety of poultry products entering the food chain.
[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.
Polystyrene microplastic exposure disturbs hepatic glycolipid metabolism at the physiological, biochemical, and transcriptomic levels in adult zebrafish
Researchers exposed adult zebrafish to polystyrene microplastics for 21 days and examined effects on liver metabolism at multiple biological levels. The study found that microplastic exposure caused significant decreases in body weight and disrupted glycolipid metabolism, with reduced levels of key metabolic enzymes and gene expression changes in the liver. Transcriptomic analysis confirmed widespread downregulation of genes related to fatty acid, amino acid, and carbon metabolism.
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.
Long-term exposure to polystyrene microplastics induces hepatotoxicity by altering lipid signatures in C57BL/6J mice
Researchers exposed mice to tiny polystyrene particles for 16 weeks and found the plastics accumulated in their livers, disrupting fat metabolism and energy production. The microplastics altered lipid profiles and interfered with key enzymes involved in cellular energy cycles. The study suggests that long-term microplastic exposure may contribute to liver damage through metabolic disruption.
