Chrebp silencing by specific siRNA for 48h induces downregulation of Fasn and Scd1 targets and cooperates with the MEK inhibitor U0126 to downregulated Plk1, Skp2, and Foxm1 genes (as determined by quantitative real-time RT-PCR) in the AKT/Ras mouse HCC cell line. Quantitative values for Chrebp, Fasn, Scd1, Plk1, Skp2, and Foxm1 mRNA levels were calculated by using the PE Biosystems Analysis software and expressed as Number target (NT). NT = 2−ΔCt, wherein ΔCt value of each sample was calculated by subtracting the average Ct value of the target gene from the average Ct value of the β-Actin gene (housekeeping gene). Experiments were conducted three times in triplicate. Tukey–Kramer test: at least P < 0.001 a, vs scrambled siRNA; b, vs DMSO (solvent); c, vs U0126; d, vs ChREBP siRNA.
