Researchers investigated the mechanism by which nanopolystyrene causes toxicity in zebrafish oocytes, finding it triggers oxidative stress, immune disruption, and mitochondrial dysfunction through changes in key gene expression pathways.
Mepanipyrim and cyprodinil induce divergent temporal patterns of AhR-mediated responses in zebrafish (Danio rerio) embryos and larvae
This study examined how two fungicides (mepanipyrim and cyprodinil) commonly found in food and water affect zebrafish embryos through the AhR signaling pathway, which regulates responses to toxic chemicals. Both fungicides triggered AhR-related toxicity in zebrafish at different time points. These findings are relevant to understanding the effects of agricultural chemical residues in aquatic environments on fish development.
Sodium nitroprusside alleviates nanoplastics-induced developmental toxicity by suppressing apoptosis, ferroptosis and inflammation
Researchers discovered that sodium nitroprusside, a compound that releases nitric oxide, could protect zebrafish larvae from the toxic effects of nanoplastics by reducing oxidative stress, cell death, and inflammation. The treatment worked by activating a signaling pathway that neutralized the harmful reactive oxygen species triggered by nanoplastic exposure. This is one of the first studies to identify a potential treatment that could counteract nanoplastic toxicity, offering hope for developing protective strategies against plastic particle exposure.
Current Aspects on the Plastic Nano- and Microparticles Toxicity in Zebrafish—Focus on the Correlation between Oxidative Stress Responses and Neurodevelopment
This review examines how nano- and micro-sized plastic particles cause toxic effects in zebrafish, focusing on the link between oxidative stress and neurodevelopmental damage. Researchers found that plastic particle exposure disrupts the balance of reactive oxygen species in cells, which can impair brain development and nervous system function. The study suggests these oxidative stress responses may serve as early warning signals of plastic particle toxicity in aquatic organisms.
A Review of in vivo Toxicity of Quantum Dots in Animal Models
This review examines the toxicity of quantum dots, tiny semiconductor nanoparticles used in medicine and imaging, across different organs in animal studies. The main toxic mechanisms involve the release of heavy metal ions and generation of harmful reactive oxygen species, which damage cells and alter gene expression. While focused on quantum dots, the oxidative stress pathways described are similar to those triggered by micro- and nanoplastics in the body.
The FOXO pathway mediates a conserved mechanism of antioxidant defense against microplastic-induced toxicity in Aurelia coerulea polyps and mouse liver
Researchers exposed both jellyfish polyps and mice to polystyrene microplastics and found that both species suffered tissue damage, oxidative stress, and activated similar antioxidant defense pathways through what is known as the FOXO signaling pathway. The gene sequences involved in this response were nearly 50% similar between the two very different species, suggesting a conserved biological defense mechanism. The study provides evidence that the cellular response to microplastic damage may be shared across a wide range of animal life.
Developmental stage-dependent carrier effects of nanoplastics on PFOS bioaccumulation and toxicity in zebrafish: Insights from toxicokinetic-toxicodynamic perspective
Researchers used a toxicokinetic-toxicodynamic framework to study how nanoplastics affect the accumulation and toxicity of the pollutant PFOS in zebrafish at different developmental stages. They found that nanoplastics reduced PFOS uptake in embryos, offering some protection, but significantly increased PFOS accumulation and toxic effects in larvae. The study highlights that nanoplastics can act as either toxicity mitigators or amplifiers depending on the organism's life stage.
Oxidative Stress and AKT-Associated Angiogenesis in a Zebrafish Model and Its Potential Application for Withanolides
Oxidative stress and AKT signaling pathway interactions were examined in a zebrafish model to evaluate the potential of withanolides, a class of plant compounds from the Solanaceae family, as modulators of angiogenesis. The study identifies several withanolides as candidates for anti-angiogenic applications based on their ability to suppress oxidative stress and AKT-associated vascular signaling.
Effects of Metamifop on Defense Systems in Monopterus albus
Researchers exposed the rice field fish Monopterus albus to the herbicide metamifop at four concentrations, finding dose-dependent increases in reactive oxygen species, oxidative damage markers, and apoptosis indicators. The results demonstrate that metamifop poses toxicity risks to non-target aquatic organisms in paddy field environments.
Lipophagy suppression: a novel mechanism for developmental disruption by nanoplastics/MC-LR in zebrafish
Researchers co-exposed zebrafish embryos to polystyrene nanoplastics and microcystin-LR (a cyanobacterial toxin) and found that combined exposure suppressed lipophagy—a cellular process that breaks down lipid droplets—more severely than either substance alone. Disruption of lipophagy impaired early development, identifying this autophagy pathway as a novel target for nanoplastic developmental toxicity.
Production of Soybean Oil Nanoemulsion (SONE) and Evaluation of Angiogenic and Embryotoxic Activity
Researchers prepared a soybean oil nanoemulsion and tested its effects on blood vessel formation (angiogenesis) in chicken eggs and toxicity in zebrafish embryos. The study is a pharmaceutical formulation paper focused on nanoemulsion properties rather than microplastic pollution.

Integrated mRNA- and miRNA-sequencing analyses unveil the underlying mechanism of tobacco pollutant-induced developmental toxicity in zebrafish embryos
Researchers exposed zebrafish embryos to cigarette smoke extract and used gene and microRNA analysis to uncover how tobacco pollutants cause developmental defects, finding disruptions in DNA repair, cell death regulation, and fat metabolism. These results help explain why prenatal tobacco exposure harms fetal development and point to specific genes that could be targeted to reduce those effects.

Intrinsic interaction inferred oxidative stress and apoptosis by Biosurfactant-microplastic hybrid reduces coordinated in vivo biotoxicity in zebrafish (Danio rerio)
Researchers developed a biosurfactant-microplastic hybrid and tested whether coating microplastics with biosurfactant could reduce their toxicity in zebrafish. They found that the biosurfactant coating reduced oxidative stress and cell death caused by the microplastics, lowering their overall biological harm. The study suggests that biosurfactants could potentially serve as a mitigation strategy for reducing microplastic toxicity in aquatic environments.
Impact of polystyrene nanoplastics on apoptosis and inflammation in zebrafish larvae: Insights from reactive oxygen species perspective
