Researchers found that polystyrene nanoplastics significantly decreased molting frequency and induced oxidative stress in adult freshwater prawns, with effects on antioxidant enzyme activities observed at environmentally relevant concentrations.
Change in energy-consuming strategy, nucleolar metabolism and physical defense in Macrobrachium rosenbergii after acute and chronic polystyrene nanoparticles exposure
Researchers examined how polystyrene nanoplastic exposure affects freshwater prawns over both short-term and long-term periods, finding significant changes in gene expression related to energy metabolism and physical defense. The study revealed that nanoplastic exposure disrupted nucleolar metabolism and triggered shifts in energy-consuming strategies, suggesting these particles pose a meaningful threat to aquatic crustaceans.
Polystyrene nanoplastics induce apoptosis, histopathological damage, and glutathione metabolism disorder in the intestine of juvenile East Asian river prawns (Macrobrachium nipponense)
Researchers exposed juvenile East Asian river prawns to different concentrations of polystyrene nanoplastics for 28 days. They found that nanoplastic exposure caused intestinal cell death, tissue damage, and disrupted the glutathione antioxidant system in a dose-dependent manner. The study suggests that nanoplastic pollution in freshwater environments could significantly compromise the intestinal health and immune defenses of crustaceans.
Effects of nanoplastics on antioxidant and immune enzyme activities and related gene expression in juvenile Macrobrachium nipponense
Researchers explored the effects of nanoplastics on survival, antioxidant activity, immune enzyme activity, and gene expression in juvenile oriental river prawns. The study found that increasing nanoplastic concentrations suppressed antioxidant and immune enzyme activities while altering related gene expression levels, indicating that nanoplastic exposure can compromise the defense systems of freshwater crustaceans.
Transcriptomic analysis following polystyrene nanoplastic stress in the Pacific white shrimp, Litopenaeus vannamei
Researchers used transcriptomic analysis to study how polystyrene nanoplastics affect gene expression in Pacific white shrimp. They found that nanoplastic exposure activated lysosome pathways and disrupted genes involved in immune response, protein processing, and metabolism. The study provides molecular-level evidence that nanoplastics can interfere with multiple biological systems in commercially important shrimp species.
Transcriptomic analysis reveals nanoplastics-induced apoptosis, autophagy and immune response in Litopenaeus vannamei
Shrimp exposed to polystyrene nanoplastics for 28 days showed dose-dependent damage to their immune systems, including increased cell death, tissue destruction in the liver-like organ, and disrupted antioxidant defenses. At high concentrations, the nanoplastics overwhelmed the shrimp's ability to fight off threats. Since shrimp are an important food source, these findings raise concerns about the quality and safety of seafood from nanoplastic-contaminated waters.
Effects of nanoplastic on cell apoptosis and ion regulation in the gills of Macrobrachium nipponense
Researchers exposed juvenile oriental river shrimp to varying concentrations of nanoplastics and examined effects on gill cell viability and ion regulation. They found that higher nanoplastic concentrations increased cell death rates, decreased ion content, reduced ATPase enzyme activity, and disrupted ion transport gene expression in gill tissues. The study suggests that nanoplastic pollution can impair critical ion regulation functions in freshwater crustaceans, with implications for aquaculture.

Acute and chronic effects of polystyrene microplastics on brine shrimp: First evidence highlighting the molecular mechanism through transcriptome analysis
Researchers investigated both acute and chronic toxicity of polystyrene microplastics on brine shrimp, using transcriptome analysis to uncover molecular mechanisms.

Ecotoxicological effects of polystyrene nanoplastics on common carp: Insights into blood parameters, DNA damage, and gene expression
Exposing common carp to polystyrene nanoplastics caused significant DNA damage in blood and brain cells, along with changes in genes related to immune function and stress response. Higher concentrations led to more severe effects, and the nanoplastics also disrupted liver antioxidant defenses. Since carp are widely consumed fish, these findings raise questions about the safety of fish from nanoplastic-contaminated waters for human consumption.
