Researchers exposed pregnant mice to polystyrene microplastics and examined how placental metabolism was affected. The study found significant changes in placental metabolic pathways that could help explain the fetal growth restriction previously observed in microplastic-exposed pregnancies.

Mice orally exposed to polystyrene or mixed polymer microspheres showed plastic particle distribution across multiple tissues including the liver, kidney, and spleen, with metabolomic analysis revealing distinct alterations in lipid, amino acid, and energy metabolism pathways.
[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.
Molecular Landscape Remodeling Unravels the Cross-Links of Microplastics-Induced Lipidomic Fluctuations, Nutrient Disorders and Energy Disarrangements
Researchers fed mice polypropylene microplastics chronically and used lipidomics and transcriptomics to show that microplastics accumulated in the liver and disrupted lipid metabolism, cholesterol homeostasis, and redox balance, with high doses causing fibrotic liver changes.
Maternal nanoplastic ingestion induces an increase in offspring body weight through altered lipid species and microbiota
Researchers found that when mother mice ingested nanoplastics derived from polystyrene and polypropylene during pregnancy and nursing, their offspring showed increased body weight gain. The weight changes were associated with alterations in fat metabolism and shifts in gut microbiome composition in the pups. The study suggests that maternal exposure to nanoplastic pollution may act as an environmental factor contributing to weight gain in offspring.

Maternal exposure to polystyrene nanoparticles retarded fetal growth and triggered metabolic disorders of placenta and fetus in mice
Researchers exposed pregnant mice to polystyrene nanoplastics through drinking water and found that higher concentrations led to significantly reduced fetal weight. The nanoplastics caused abnormal cell structures in the placenta and disrupted metabolic processes in both placental tissue and fetal livers. The study suggests that maternal nanoplastic exposure during pregnancy can cross the placental barrier and interfere with normal fetal growth and metabolism.
Maternal Polystyrene Microplastic Exposure during Gestation and Lactation Altered Metabolic Homeostasis in the Dams and Their F1 and F2 Offspring
Researchers exposed pregnant mice to polystyrene microplastics during pregnancy and nursing and found significant metabolic disruptions in both the mothers and their offspring across two generations. The microplastics altered lipid metabolism, gut microbiota composition, and key metabolic signaling pathways. The study suggests that microplastic exposure during critical developmental windows may have lasting health consequences that pass to future generations.
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.
