摘要:

以肝脏绿色荧光转基因斑马鱼T3(lfabp:EGFP)为模型,研究水环境典型重金属污染物铜(CuCl2)、汞(HgCl2)和铅(Pb(Ac)2)在较低浓度暴露下对仔鱼(72~144 hpf)肝脏发育的影响。结果显示,各暴露组存活率均在95%以上;CuCl2和HgCl2在1 μmol/L时均能够引起鳔发育或充气异常;3种化合物均能够显著减小肝脏荧光面积和光密度。相同暴露浓度下,CuCl2抑制肝脏发育的能力强于Pb(Ac)2和HgCl2,但HgCl2在0.01 μmol/L时就能够显著抑制肝脏发育;CuCl2和Pb(Ac)2抑制lfabp表达量的能力强于HgCl2,且Pb(Ac)2在0.01 μmol/L时就能够显著抑制lfabp表达。结果表明,3种重金属化合物均能够显著抑制肝脏发育;转基因斑马鱼仔鱼可以作为检测环境污染物肝脏发育毒性的首选模型。

Abstract:

We addressed the impact of three typical heavy metal pollutants (copper chloride, mercury chloride and lead acetate) on liver growth of zebrafish larvae (72~144 hpf) with a liver green fluorescence transgenic zebrafish T3 (lfabp:EGFP) as a model. Results show that the survival rates of all groups are all more than 95%. CuCl2 and HgCl2 of 1 μmol/L can all cause abnormality of swimbladder growth or inflation. The three heavy metal compounds can all significantly reduce liver fluorescence area and integral optical density. CuCl2 has more powerful inhibition capability for liver growth than Pb(Ac)2 and HgCl2 under identical exposure concentration. However, HgCl2 of 0.01 μmol/L can inhibit liver growth. Inhibition capability of lfabp expression of CuCl2 and Pb(Ac)2 is greater that of HgCl2. Moreover, Pb(Ac)2 of 0.01 μmol/L can inhibit the expression of lfabp. Results show that the three heavy metal compounds can all significantly inhibit liver growth. Transgenic zebrafish larvae can serve as priority model for detection of environmental contaminants caused liver growth toxicity.
