Fecha de publicación: | 16-sep-2022 | Editor: | Elsevier | Citación: | Toxicology in Vitro 85: 105477 (2022) | Resumen: | Precision-cut tissue slices (PCTS) are frequently used in mammalian research, but its application in the area of aquatic toxicology is still humble. This work proposes the use of PCTS to investigate the effects of the antimicrobial triclosan (TCS) in the mussel Mytilus galloprovincialis. PCTS sectioned from the digestive gland (400 μm) were exposed to 10, 100, and 500 nM TCS for 24 h, and the expression of selected genes, together with the biomarkers, carboxylesterases (CbE) and glutathione S-transferases (GST), and the analysis of lipids in PCTS and culture medium, were used to investigate the molecular initiating events of triclosan in the digestive gland of mussels. Significant dysregulation in the expression of phenylalanine-4-hydroxylase (PAH), glutamate dehydrogenase (GDH), fatty acid synthase (FASN), and 7-dehydrocholesterol reductase (DHCR7), involved in energy, phenylalanine and lipid metabolism, were detected. The analysis of lipids evidenced significant changes in cholesteryl esters (CEs) and membrane lipids in the culture medium of exposed PCTS, suggesting dysregulation of energy and lipid metabolism that can affect lipid dynamics in mussels exposed to triclosan. | Versión del editor: | https://doi.org/10.1016/j.tiv.2022.105477 | URI: | http://hdl.handle.net/10261/281388 | DOI: | 10.1016/j.tiv.2022.105477 | ISSN: | 08872333 |
