A flounder (Paralichthys olivaceus) gill cell line as in vitro acute assay system of nonylphenol cytotoxicity
A cell line (FG cells) derived from a gill of the flounder, Paralichthys olivaceus were used to determine the cytotoxic effects of nonylphenol (NP). Cytotoxicity was measured by three endpoint systems: neutral red (NR) uptake assay, methyl thiazolyl tetrazolium (MTT) assay and cell protein assay. The result showed that NP was cytotoxic to FG cells at all tested concentrations, and toxicity increased as the concentration of NP was progressively increased. The 24 h-IC50 values of NP were 39.81, 37.76 and 38.22 μmol/L for NR uptake, MTT assay and cell protein assay, respectively. Moreover, the morphological changes of FG cells were also studied at the concentration of 30 μmol/L for 24 h. Cells morphology were markedly altered by NP observed under a scanning electron microscopy, as evidenced by swelling cells, two and more nucleolus and an increased number of lipid particles. This would suggest that the FG cell line is a suitable bioindicator for the screening of the acute toxicity of NP.
