摘要


Trace metal ions and trace organic compounds are common co-contaminants in the environment that pose risks to human health. We evaluated the effects of four metal ions (As(3+), Cu(2+), Hg(2+), and Zn(2+)) on 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induced cytotoxicity and the expression of the cytochrome P4501A1 gene (cyp1a1) in the zebrafish liver (ZFL) cell line. A metal accumulation study showed that Cu and Zn did not accumulate in ZFL cells. However, As and Hg did accumulate, which resulted in the inhibition of TCDD-mediated induction of cyp1a1 mRNA and protein expression, and 7-ethoxyresorufin O-deethylase activity. A luciferase assay showed that both As(3+) and Hg(2+) inhibited the TCDD-induced activity of gene constructs containing either synthetic 3XRE or a distal cyp1a1 promoter region, implying that the decreased levels of TCDD-induced cyp1a1 were due to transcriptional effects. A proteomic study showed that the toxic effects of As(3+) might be due to changes in cellular metabolic processes, the cellular stimulation response and the cellular redox state in ZFL cells.
