Figure 2.

Time course changes in mRNA levels of transcription factors in HepG2 cells exposed to 1mM ethanol concentration expressed as a relative fold change compared to control HepG2 cells (not exposed to ethanol). White, gray and black bars represent 2, 4 and 6 hr exposure times, respectively. Results are the mean of six different experiments (n=6). Error bars represents standard deviations. Significance is shown as the difference between ethanol-treated and control cells at 2 h (* p < 0.05), 4 h († p < 0.05), and 6 h (# p < 0.05).
