Summary: The 2010 Deepwater Horizon oil spill had an impact on the spawning season of coastal species like red drum, which develop rapidly and are sensitive to crude oil exposure. Despite increased pericardial area in red drum larvae exposed to oil, cholesterol biosynthetic genes were not affected. However, free cholesterol levels in the larvae increased significantly, potentially playing a role in the observed oil toxicity across fish species.

Summary: This study cloned and identified SoACP5 gene from red drum and found that it plays an important role in immune defense. SoACP5 is widely distributed in healthy red drum tissues, with the highest expression in the gills. Its expression significantly increases after infection with Edwardsiella tarda. The purified SoACP5 protein has phosphatase activity and can promote the proliferation of peripheral blood leukocytes. The evaluation of SoACP5's defense against bacterial infection is of great significance.

Summary: Mortality rates of marine fish larvae are high and vary among individuals and cohorts, and the causes of this variation are unknown. Through transcriptomics, we examined the molecular basis of predator evasion and foraging efficiency in larval red drum. We identified functional gene networks associated with these traits and found that energy metabolism and neural activation were important factors influencing larval survival skills.

Summary: The global sequencing of microRNA (miRNA) and mRNA expression profiles in fish exposed to crude oil revealed consistently dysregulated miRNAs with predicted roles in cardiovascular, neurological, and visually-mediated pathways. Two miRNAs, miR-203a and miR-34b, were found to be primary targets of crude oil. Inhibition of miR-203a and overexpression of miR-34b resulted in neurological and eye toxicity responses similar to those caused by oil exposure.

Summary: Recreational angling is economically important, and catch-and-release (CAR) is a conservation strategy used to offset its population-level consequences. This study focused on defining the injury and recovery profiles in red drum fish following exhaustive exercise. The results showed that smaller fish recovered faster with a maximum injury effect size, while larger fish had slower recovery rates and were more susceptible to the ancillary effects of exercise injury.

Summary: This study investigated the contribution of plastic cutting boards to the presence of microplastics in human food. The chopping style and board material were found to influence the release of microplastics. Polypropylene cutting boards released more microplastics than polyethylene boards, and chopping with vegetables resulted in higher microplastic release. The study estimated the annual exposure of microplastics from chopping boards and found that they could be a substantial source in human food. Preliminary toxicity tests showed no adverse effects of polyethylene microplastics on cell viability.

Summary: Through experiments, it was found that perfluorobutanesulfonic acid (PFBA), perfluorooctanoic acid (PFOA), and perfluorononanoic acid (PFNA) with different carbon chain lengths significantly reduced the antibacterial ability of zebrafish during the early-life stage, suppressed the innate and adaptive immune systems, and showed a positive correlation with carbon chain length. It was also discovered that PFASs exerted immunomodulatory effects by activating downstream genes of the Toll-like receptor, and inhibiting the Toll-like receptor pathway could alleviate the immunotoxicity of PFASs.

Summary: Hematite, a natural mineral with multiple crystal facets, plays a significant role in the migration and transformation of pollutants in the environment. This study investigated the photoaging of polystyrene microplastics (PS-MPs) on different crystal planes of hematite and identified the underlying mechanisms. The {012} crystal facet of hematite exhibited the strongest performance in PS-MPs photoaging, with particle size reduction and surface oxidation. The narrower bandgap and lower activation energy barrier of the {012} facet promoted effective charge carrier separation and OH formation.

Summary: Polycyclic aromatic hydrocarbons from crude oil can negatively impact the health of fish. However, the effects of dysbiosis in fish gut microbial communities and its influence on fish toxic response following exposure have been poorly characterized in marine species. This study used metagenomic and metatranscriptomic sequencing to analyze the microbial communities in juvenile Atlantic cod exposed to dispersed crude oil. The results showed significant changes in microbial composition and function, as well as altered pathways related to energy, biosynthesis, and cellular structure. The study also found common pathways between fish transcriptomic profiling and microbial functional annotations, suggesting the importance of gut microbial communities in fish response to oil exposure.

Summary: Anthropogenic discharge of nutrients, metals, and antibiotics poses multiple threats to aquatic ecosystems and human health, including eutrophication and introduction of resistance genes into pathogens. The link between microbial communities, resistance genes, and eutrophication levels in urban lakes is complex and unclear, but crucial for risk assessment. A study on five urban lakes found significant differences in microbial diversity, antibiotic resistance genes (ARGs), and metal resistance genes (MRGs). Microbial communities and mobile genetic elements (MGEs) were identified as the main drivers of resistance gene profiles, while external environmental factors played an indirect role. The study provides insights into the potential dissemination risk of ARGs in urban lakes.
