Abstract
Bisphenol A (BPA), a widely used chemical to produce polycarbonate plastics, has become an ubiquitous pollutant due to its extensive use. Its endocrine disrupting properties have been documented in several studies, as well as its potential to induce metabolic and reproductive impairments at environmentally relevant concentrations. Recent insights highlighted the role of the Endocannabinoid System (ECS) in energy homeostasis and lipid metabolism. In fact, disruption of the ECS may induce metabolic alterations among other effects. Thus, the main objective of this study was to investigate the disruptive effects of environmentally relevant concentrations of BPA on the ECS of female zebrafish liver and brain. Adult female zebrafish were exposed for 3 weeks to three different concentrations of BPA (5 μg/L; 10 μg/L; 20 μg/L). We observed changes in the expression of a number of genes involved in the Anandamide (AEA) and 2-Arachidonoylglycerol (2-AG) metabolism in the liver and brain, as well as altered levels of endocannabinoids and endocannabinoid-like mediators. These changes were associated with greater presence of hepatic lipid vacuoles, following exposure to the highest concentration of BPA (20 μg/L) tested, although there were no changes in food intake and in the expression of the molecular markers for appetite. The overall results support the hypothesis that exposure to BPA induced changes in the central and hepatic ECS system of adult female zebrafish causing the increase of the area covered by lipids in the liver at the highest concentration tested, but not via food intake.
