Sodium Hypochlorite (NaClO) Disturbed Lipid Metabolism in Larval Zebrafish (Danio rerio), as Revealed by Lipidomics and Transcriptomics Analyses.
Sodium hypochlorite (NaClO) has been widely utilized since the initial outbreak of coronavirus disease (COVID-19). The widespread use of NaClO means that it can directly enter aquatic ecosystems through wastewater discharge. In this study, we analyzed the expression of PPAR-γ, FAS, and ACC1, which significantly increased in larval zebrafish following exposure to 300 μg/L NaClO for 7 days. Additionally, we examined the effects of high concentrations of NaClO on zebrafish through non-targeted lipidomics and transcriptomics. A total of 44 characteristic lipid molecules were identified using non-targeted lipidomics; an absolute quantitative analysis revealed that the contents of these subclasses of lipids decreased significantly following exposure to 300 μg/L NaClO for 7 days. The levels of triglyceride (TG), phosphatidylethanolamines (PE), and diglyceride (DG) were particularly affected. Transcriptomic analysis revealed that exposure to 300 μg/L NaClO could significantly disrupt global gene transcription in larval zebrafish. Interestingly, more than 700 differentially expressed genes (DEGs) were identified, primarily associated with lipid metabolism and glycometabolism pathways. Overall, our study provided new insights into the toxicological effects of chlorine-containing disinfectants in aquatic organisms.

期刊介绍:
The Journal accepts papers describing work that furthers our understanding of the exposure, effects, and risks of chemicals and materials in humans and the natural environment as well as approaches to assess and/or manage the toxicological and ecotoxicological risks of chemicals and materials. The journal covers a wide range of toxic substances, including metals, pesticides, pharmaceuticals, biocides, nanomaterials, and polymers such as micro- and mesoplastics. Toxics accepts papers covering:
The occurrence, transport, and fate of chemicals and materials in different systems (e.g., food, air, water, soil);
Exposure of humans and the environment to toxic chemicals and materials as well as modelling and experimental approaches for characterizing the exposure in, e.g., water, air, soil, food, and consumer products;
Uptake, metabolism, and effects of chemicals and materials in a wide range of systems including in-vitro toxicological assays, aquatic and terrestrial organisms and ecosystems, model mammalian systems, and humans;
Approaches to assess the risks of chemicals and materials to humans and the environment;
Methodologies to eliminate or reduce the exposure of humans and the environment to toxic chemicals and materials.
