**Figure 4. **LFE up-regulates Beclin-1, LC3-I and LC3-II expression in HSV-1 infected SIRC cells. Cells pretreated with 0.05, 0.1 or 0.2
μg/ml of LFE for 1.5 h then infected with HSV-1 at 1 MOI for 24 h. The protein levels were normalized against the β-actin
signal. Bars are means ± standard error of the mean (SEM). **A**, **B**, **C**, **D**: bars with different letters differed (p<0.05).
