ClearTranscriptome Analysis of Gills Provides Insights Into Translation Changes Under Hypoxic Stress and Reoxygenation in Golden Pompano, Trachinotus ovatus (Linnaeus 1758)
This transcriptome study found that oxygen deprivation suppresses immune genes in the gills of golden pompano fish, potentially explaining why fish are more susceptible to infections under low-oxygen aquaculture conditions. The molecular findings support improved oxygen management practices in fish farming to protect both animal welfare and food quality.
Transcriptome Analysis Revealed the Early Heat Stress Response in the Brain of Chinese Tongue Sole (Cynoglossus semilaevis)
Researchers used transcriptome analysis to study how the brains of Chinese tongue sole fish respond to short-term heat stress. They identified distinct gene expression patterns in male and female fish, with key pathways related to cortisol production, immune signaling, and stress-response genes like heat shock proteins. The study provides new insights into the sex-specific brain mechanisms fish use to cope with temperature changes.
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.
Transcriptome alterations in zebrafish gill after exposure to different sizes of microplastics
Researchers found that microplastic exposure in zebrafish gills caused size-dependent transcriptomic changes, with smaller particles triggering more differentially expressed genes related to immune response, oxidative stress, and apoptosis pathways compared to larger particles.
Transcriptomic, histological and biochemical analyses of Macrobrachium nipponense response to acute heat stress
This study examined how acute heat stress affects the physiology of the oriental river prawn, finding significant changes in gene expression and biochemistry that provide insight into how this commercially important species responds to warming water temperatures.
The effects of exposure to microplastics on grass carp (Ctenopharyngodon idella) at the physiological, biochemical, and transcriptomic levels
Researchers exposed grass carp to microplastics at two concentrations for 21 days and observed liver damage, inhibited growth, and increased oxidative stress. Transcriptome analysis revealed over 1,500 differentially expressed genes related to immune response, metabolism, and cellular stress pathways. The study suggests that microplastic exposure can trigger broad physiological and molecular disruptions in freshwater fish.
Effects of different temperatures on Leiocassis longirostris gill structure and intestinal microbial composition
Researchers exposed a freshwater catfish species to cold (4°C), normal (26°C), and hot (32°C) water temperatures and found that both extremes damaged gill tissue and disrupted the balance of gut bacteria, with cold stress causing a larger shift toward opportunistic pathogens. The findings reveal how temperature stress compromises fish immune health, relevant as climate change increases the frequency of extreme weather events.
Transcriptome Analysis to Study the Molecular Response in the Gill and Hepatopancreas Tissues of Macrobrachium nipponense to Salinity Acclimation
Researchers used Illumina RNA sequencing to perform transcriptome analyses of gill and hepatopancreas tissues from the freshwater prawn Macrobrachium nipponense exposed to three salinity levels. They identified differentially expressed genes related to ion transport, oxidative phosphorylation, and glycometabolism, and confirmed carbonic anhydrase as a key regulator of osmotic adaptation through in situ hybridization.
Molecular responses to pollution stress in glass eels (Anguilla anguilla): Gene expression changes associated with varying contamination levels and temperature across estuaries
Researchers measured gene expression in European eel glass eels entering estuaries with varying levels of microplastic and heavy metal contamination, finding that pollution and temperature shifts alter stress-response and metabolic gene expression in ways that may impair survival.
Transcriptome wide analyses reveal intraspecific diversity in thermal stress responses of a dominant habitat‐forming species
Researchers examined transcriptome-wide diversity in how coral species respond to thermal stress, revealing intraspecific genetic variation that may influence resilience to warming oceans. The findings highlight the importance of genetic diversity within coral populations for predicting reef responses to climate change.
Revealing the Impact of Polystyrene Nanoplastics on Gill Tissues of the Intertidal Clam, Gafrarium Divaricatum (Gmelin, 1791) using Transcriptomics Approach
Researchers exposed intertidal clams to polystyrene nanoplastics and used transcriptomics to assess gill tissue impacts, finding 1,182 upregulated and 1,626 downregulated genes related to immune modulation, antioxidant defense, and apoptosis. Histopathological examination revealed structural damage to gill tissues including ciliary erosion, lamellae fusion, and lipofuscin accumulation. The study establishes a high-quality genomic resource for this clam species while demonstrating the ecotoxicological effects of nanoplastics on sessile marine bivalves.
