ClearPhenotypic and Gene Expression Alterations in Aquatic Organisms Exposed to Microplastics
This review summarizes research on how microplastics affect aquatic animals at the genetic level, covering changes in hatching, development, and growth. Microplastics, especially when combined with other pollutants, trigger abnormal gene activity in antioxidant and stress-response systems in fish and other water organisms. These genetic disruptions in aquatic life are relevant to human health because affected organisms can enter the food chain through seafood.
Experimental Approaches for Characterizing the Endocrine-Disrupting Effects of Environmental Chemicals in Fish
This review examines experimental approaches used to characterize the endocrine-disrupting effects of environmental chemicals, including microplastics, in fish. Researchers summarize methods spanning molecular, cellular, and whole-organism levels, including gene expression analysis, hormone measurements, and reproductive assays. The study provides a framework for evaluating how pollutants interfere with hormonal regulation in aquatic vertebrates and highlights the value of fish as sentinel species.

The effect of environmental stressors on growth in fish and its endocrine control
This review examines how environmental stressors, including pollution and climate change, affect fish growth through hormonal disruption. Pollutants like microplastics and heavy metals can interfere with the growth hormone system, leading to stunted development and reproductive problems in fish. These effects on fish health are relevant to humans because they can reduce the quality and safety of fish as a food source.

Researchers studied how microplastics and halogenated contaminants in fish feed affected the toxicokinetics of those contaminants, finding that microplastics in feed altered how persistent organic pollutants were absorbed and distributed in fish tissues.
The role of environmental stress in fish health: A review
This review examines how environmental stressors including temperature changes, pesticide contamination, microplastics, and algal blooms affect fish health. Researchers found that these factors substantially influence fish growth, reproduction, respiration, and metabolic function. The study emphasizes the need for new strategies to address the growing impact of environmental changes on aquatic ecosystems and the global fish economy.
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.
Evaluation of Detoxification‐Related Gene Expression, Oxidative Stress Biomarkers, and Blood Biochemical Parameters in Common Carp ( Cyprinus carpio ) Co‐Exposed to Polyethylene Microplastics and Deltamethrin
Researchers investigated whether polyethylene microplastics worsen the toxic effects of the insecticide deltamethrin in juvenile common carp over a 30-day exposure. The study found that co-exposure to microplastics and deltamethrin affected detoxification-related gene expression, oxidative stress biomarkers, and blood biochemistry, suggesting that microplastics can modify the bioavailability and toxicity of co-occurring pesticides in fish.
Transcriptome analysis of discus fish (Symphysodon haraldi) skin and brain to identify genes involved in ‘milk’ secretion during parental care
Researchers analyzed the gene expression profiles of discus fish skin and brain to understand the molecular basis of their unique parental behavior of feeding larvae with skin mucus. This is a fish biology study with no direct relevance to microplastics or environmental contamination.
Effects of microplastics on the toxicity of co-existing pollutants to fish: A meta-analysis
Meta-analysis of 1,380 biological endpoints from 55 studies found that microplastics in co-existing pollutant solutions significantly increased toxicity to fish beyond what the pollutants caused alone, particularly elevating immune system damage, metabolic disruption, and oxidative stress. The effect depended on fish life stage and microplastic size, but not on pollutant or polymer type.
