Transcriptomic and metabolomic analysis reveals hepatic lipid metabolism disruption in Japanese quail under polystyrene microplastics exposure

Researchers fed Japanese quail polystyrene microplastics at environmentally relevant concentrations for 35 days and analyzed liver effects using transcriptomics and metabolomics. Low doses caused increased food intake and weight gain with liver lipid accumulation, while high doses led to decreased intake and weight loss, suggesting a hormetic dose-response pattern. The study found that microplastic exposure disrupted hepatic lipid metabolism pathways and caused liver oxidative stress in birds.

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.
