ClearHypoxia in the Blue Mussel Mytilus chilensis Induces Transcriptome Shift Associated with Endoplasmic Reticulum Stress, Metabolism, and Immune Response.
Scientists used gene expression analysis to study how low-oxygen conditions affect the blue mussel Mytilus chilensis at the molecular level. Researchers found that hypoxia triggered stress responses in the mussels' gills, digestive glands, and muscles, including cellular stress pathways, metabolic shifts, and immune changes. The study highlights how climate-driven oxygen depletion in coastal waters can stress economically important shellfish species.

Differential responses of selectively bred mussels (Perna canaliculus) to heat stress—survival, immunology, gene expression and microbiome diversity
This study examined how selectively bred green-lipped mussels respond to heat stress, finding that genetic background significantly influenced survival rates, immune responses, and gene expression during heat challenges. While not directly about microplastics, the research is relevant because environmental stressors like microplastic pollution can compound heat stress effects on shellfish. Understanding how marine organisms cope with stress helps predict how additional pressures from plastic pollution might affect seafood species.
Starvation shrinks the mussel foot secretory glands and impairs the byssal attachment
Researchers investigated the effect of starvation on byssal attachment in the hard-shelled mussel Mytilus coruscus, finding through histological analysis and gene expression studies that 7–21 days of starvation shrinks foot secretory glands and reduces expression of mussel foot proteins, impairing byssus secretion and substrate attachment.
Responses of Mytilus galloprovincialis in a Multi-Stressor Scenario: Effects of an Invasive Seaweed Exudate and Microplastic Pollution under Ocean Warming
Researchers exposed mussels to a combination of invasive seaweed exudate, polyethylene microplastics, and elevated temperatures to study their combined effects. The study found that simultaneous exposure to all three stressors greatly reduced byssal thread production and depleted antioxidant defenses in gill tissue, suggesting that multiple environmental stressors can amplify harmful effects on marine organisms.
Impacts of microplastics exposure on mussel (Mytilus edulis) gut microbiota
Researchers exposed marine mussels (Mytilus edulis) to microplastics and analyzed changes to their gut microbiota, finding significant shifts in microbial community composition that could affect digestion, immunity, and overall health.
Physiological and transcriptome analysis of Mytilus coruscus in response to Prorocentrum lima and microplastics
The combined effects of diarrhetic shellfish toxin and microplastics on the mussel Mytilus coruscus were assessed at physiological and transcriptomic levels, revealing synergistic disruption of immune function, antioxidant responses, and metabolic pathways. The study provides molecular-level evidence of interactive toxicity between two common coastal contaminants.
Exploring the Potential of Metatranscriptomics to Describe Microbial Communities and Their Effects in Molluscs
Metatranscriptomics revealed a more complete picture of mussel microbiomes — including bacteria, viruses, fungi, and protozoans — than traditional 16S sequencing alone. The approach also identified host genes whose expression changed with pathogen load, providing new insights into how molluscs respond to microbial infections.
Molecular biomarker responses in the freshwater mussel Anodonta anatina exposed to an industrial wastewater effluent
Researchers exposed freshwater mussels to industrial wastewater effluent containing elevated levels of copper, nickel, and zinc, then measured a panel of molecular stress markers in gill and digestive tissue. While most markers showed little change, increased nerve enzyme activity and heat shock protein expression were detected, suggesting mussels can serve as sensitive pollution bioindicators but require more research to standardize responses.

Researchers used iTRAQ-based proteomics to reveal that okadaic acid exposure in scallops (Chlamys farreri) triggers oxidative stress, immune suppression, and disruption of cytoskeletal and energy metabolism pathways, providing mechanistic insights into shellfish toxicity during harmful algal blooms.
Profiling of microRNAs and mRNAs in marine mussel Mytilus galloprovincialis
Researchers used deep sequencing to profile microRNAs in the Mediterranean blue mussel Mytilus galloprovincialis, identifying 137 miRNA sequences — 104 conserved across species and 33 potentially novel — providing a genomic baseline for studying how this ecologically important species responds to environmental stressors.
