Toxicity, gut microbiota and metabolome effects after copper exposure during early life in SD rats
Copyright © 2020 Elsevier B.V. All rights reserved..
Copper, an essential microelement, can still be harmful to health and has a significant impact on the gut microbiota, which is closely related to health when copper is ingested excessively. However, the effects of low dose exposure to copper early in life on health and the gut microbiota are not well understood. Here, the effects of early-life exposure of copper on the toxicity, gut microbiota and the metabolome were investigated in Sprague-Dawley (SD) rats. The results showed that 0.20 and 1.00 mg/kg BW copper early-life exposure in SD rats significantly increased ALT, AST, and ALP levels in the blood and caused liver damage. Copper exposure had a dose-dependent effect on the alpha and beta diversity and reduced the abundance of probiotics, the ratio of Firmicutes to Bacteroidetes (F/B), and changed the abundance of fat metabolism and intestinal inflammation-related bacteria. The results of the fecal metabolome also demonstrated the effects of early-life copper exposure on liver damage and intestinal inflammation-related metabolic pathways. Together, our findings demonstrated that copper exposure during early life induced liver damage and gut microbiota dysbiosis and affected the relevant metabolic pathways.
