Figure 1: Effect of long-term cisTPD treatment on CYP2B1 and CYP2B2 genes expression in normal diet and HFD rat livers. Total RNAs were prepared and subjected to RT-PCR for measurement of mRNA. Fold change was expressed by taking the corresponding value of the control rats as one. Bars mean ± S.D (n=5). *Indicate a significant difference from control animals (p< 0.05); †Indicate a significant difference from HFD animals (p< 0.05).
