Figure 5: Levels of expression of miRNA-122 in tumor tissue determined by real time PCR. C1= benzoimidazoquinazoline, C2= Benzimidazotriazine. Values are expressed as mean of log 2 fold change vs the normal group ± SD. The expression of the normal group is normalized to 1 where log2(1) = zero. Data were analyzed using ANOVA followed by Bonferroni post hoc test. * significantly different compared to the normal group, # significantly different compared to the control group, $ significantly different compared to the cisplatin group. Differences were considered significant at p <0.05.
