Sulfasalazine Enhances Copper Toxicity in Danio rerio Larvae: Divergent Protective Roles of Deferoxamine and Ferrostatin‐1

Environmental Toxicology, EarlyView.
ABSTRACT Copper is an environmental contaminant capable of disrupting redox homeostasis and impairing antioxidant defenses in aquatic organisms, thereby increasing susceptibility to oxidative stress. The cystine/glutamate antiporter (system xc−) plays a central role in maintaining intracellular glutathione (GSH) levels, a major antioxidant defense ...

Climate‐Modulated Particle Toxicity: Acute Exposure to an Environmentally Informed Microplastic Mixture Induces Sex‐Dependent Systemic Reorganization in Swiss Mice

Environmental Toxicology, EarlyView.
ABSTRACT Microplastic (MP) pollution is widely recognized as an emerging environmental threat. Yet, most studies still rely on controlled experimental conditions that poorly reflect environmental complexity, potentially underestimating risks under realistic scenarios, particularly during short‐term exposures. Here, we tested whether acute oral exposure

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Increased energetic cost of movement reduces reproductive output in zebrafish at different temperatures and water flow rates

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Locomotion consumes a large proportion of individual energy budgets and may impose energetic constraints on other fitness‐related traits particularly under variable environmental conditions.

Transcriptional breakpoints as predictors of thermal thresholds in a climate‐impacted stenothermal fish

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The biogeography of ectotherms is greatly influenced by their thermal tolerance, which is expected to be tightly coupled to aerobic performance. However, preferred temperatures of ectotherms often deviate substantially from aerobic performance optima. This suggests that

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

Integrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Daily variation in the shoaling behavior of zebrafish Danio rerio

Current Zoology, 2012
Shoaling behavior provides numerous fitness benefits for fish, including enhanced access to mates, increased success in foraging and protection from predators. We were interested in determining whether shoaling intensity differed throughout the day.

Exploring Interactive Effects of Arsenic and Selenium Exposure on Larval Zebrafish (Danio rerio). [PDF]

Environ Toxicol
ABSTRACT Arsenic contamination in aquatic ecosystems is a major environmental concern. Selenium (Se) helps mitigate oxidative stress and hence could reduce the toxic effects of arsenic. However, Se can also be toxic at high concentrations. Given that these metalloids commonly co‐occur in the environment, there is a pressing need for further research ...

Genome Expansion of ZPB1(a) and ZPC1(a) in Basal Species or Liver Expression of ZPB1a and ZPC1aa in Advanced Species, Two Different Strategies to Ensure Sufficient ZP Synthesis in Teleosts

Integrative Zoology, EarlyView.
We found that teleosts employed two different strategies to ensure sufficient ZP (zona pellucida) synthesis: expansion of ZPB1(a) and ZPC1(a) in basal species or liver expression of ZPB1a and ZPC1aa in advanced species. The N‐terminus of expanded ZPB1(a) or ZPC1(a) and liver‐expressed ZPB1a contains repeated units or low‐complexity regions to form ...
