Effects of Polystyrene Microplastic Exposure on Liver Cell Damage, Oxidative Stress, and Gene Expression in Juvenile Crucian Carp (Carassius auratus)

A considerable quantity of microplastic debris exists in the environment and toxicity these materials has a notable impact on aquatic ecosystems. In this paper, 50–500 µm polystyrene microplastics (exposure concentrations were 200 µg/L, 800 3200 µg/L concentrations) selected to study effects (PS-MPs) cell morphology, detoxification enzyme activity, mRNA expression liver tissues crucian carp juveniles. The results demonstrated that: (1) Different PS-MPs cause varying degrees pathological oxidative damage tissue cells carp. higher concentration microplastics, lower antioxidant (CAT, GST, SOD) activity greater damage. These demonstrate typical dose–effect relationship. (2) Principal component analysis Spearman’s correlation that four components, namely glutathione S-transferase (GST) its related genes (GSTpi, GSTα), along with catalase (CAT), contributed most observed outcome. components relatively high level responsiveness PS-MP exposure can be employed as ecotoxicological indicators microplastics. (3) This experiment evaluated five three treatments, which found had different gene tested involved response pathways associated virulence. study, was determined at cellular, protein, levels, combined principal identify sensitivity provide scientific basis for ecological risk assessment safe use

Differential effects of foodborne and waterborne micro(nano)plastics exposure on fish liver metabolism and gut microbiota community

Journal of Hazardous Materials, Journal Year: 2025, Volume and Issue: 488, P. 137471 - 137471

Micro(nano)plastics (MNPs) primarily enter fish through two routes: directly ingestion via their diets and respiratory filtration gills. However, the specific impacts of these routes on liver metabolism remain largely unknown. Here, we investigated gene expression profiles Nile tilapia Oreochromis niloticus following equivalent doses foodborne waterborne MNPs exposure. While phenotypes O. showed minimal differences between exposure routes, significant variations were observed in response patterns. Using WGCNA, identified key networks KEGG pathways associated with each type. The primary transcription factors regulating changes thrb for fosl2 stimulus induced metabolic disorders circadian rhythm, whereas inflammatory responses to affect host metabolism. By integrating alterations gut microbiota enrichment data, further found that Firmicutes, Fusobacteriota, Proteobacteria, Chloroflexi jointly regulated mapk13 during exposure, most leading genes was predominantly influenced by Firmicutes. Collectively, our study demonstrated a distinct pattern microbiota-gene gut-liver axis

Toxicity and Health Effects of Microplastics

Published: Feb. 21, 2025

Microplastics have received growing concerns from both society and the scientific community due to their widespread presence in environment potential toxic effects. In this chapter, we present effects of microplastics on estuarine marine organisms, freshwater soil human health, including enrichment organisms mechanisms. addition, compound toxicity with other environmental pollutants is also discussed.
