Effects of salinity acclimation on histological characteristics and miRNA expression profiles of scales in juvenile rainbow trout (Oncorhynchus mykiss)
Researchers investigated how rainbow trout adapt their scales at the molecular level when moved from freshwater to saltwater, identifying specific small RNA molecules (microRNAs) that regulate bone metabolism during the transition. This foundational biology work helps explain how fish adapt to changing environments, relevant to aquaculture and to understanding how fish physiology responds to environmental stressors like microplastic exposure.
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.
Transcriptome analysis provides insights into copper toxicology in piebald naked carp (Gymnocypris eckloni)
Researchers exposed piebald naked carp to copper — a common water pollutant — and found it significantly disrupted gene activity in the gills and liver, particularly genes involved in building proteins, suggesting that fish respond to metal-induced stress by broadly slowing down protein production as a protective mechanism.
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. While acute exposure did not significantly affect survival, chronic exposure led to concentration-dependent bioaccumulation and increased reactive oxygen species generation, with gene expression analysis revealing disrupted metabolic and stress response pathways.
