Abstract: BACKGROUND & AIM: To study on the susceptibility of two human-derived hepatic cell lines in evaluating DNA damage induced by 3-chloro-4-dichloromethyl-5-hydroxy-2(5H)-furanone(MX). MATERIALS AND METHODS: Using single cell gel electrophoresis assay, to evaluate the DNA damage induced by MX in human hepatocellular carcinoma cell lines(HepG2) and human fetal hepatocytes (L-02). RESULTS: MX could induce HepG2 and L-02 DNA single strand breaks at the concentrations of 30 and 100 μmol/L, respectively. The length of DNA migration induced by MX increased significantly in comparison to solvent control (DMSO) in a dose-response manner(P<0.05). Moderate or greater DNA damages induced by MX in HepG2 were more serious than that of L-02(χ2=20.985;8.0;11.97, P<0.05). CONCLUSION: HepG2 was more susceptible than L-02 cells to DNA damage induced by MX evaluated by using single cell gel electrophoresis assay.
