Figure 2: Effect of MFE on EC-induced toxicity in HepG2 cells. (a) The quantitative data of cell viability; HepG2 cells were treated with different concentrations of EC ranging from 0 to 100 mM for 24 h. (b) The quantitative data of cell viability; HepG2 cells were treated with different concentrations of MFE (0.5 mg/mL, 1 mg/mL, and 2 mg/mL) for 24 h. (c) Nuclear staining of HepG2 cells with Hoechst 33258. (d) The quantitative data of cell viability; HepG2 cells were incubated with 60 mM EC for 24 h in the presence or absence of MFE (0.5 mg/mL, 1 mg/mL, and 2 mg/mL). Results were expressed as mean value ± standard deviations. represents significant difference compared with EC group. EC, ethyl carbamate; MFE, mulberry fruit extract.
