The Wnt/β-catenin pathway was down-regulated in the CKI group and up-regulated in the DDP group. a Quantitative RT-PCR analysis revealed that the expression of β-catenin, TCF4, LEF1, CyclinD1 and c-Myc (mean ± SD) were lower in CKI group than those in the control group. Most of the differences were statistically significant (* P < 0.05). The expression of β-catenin, TCF4, LEF1, CyclinD1 and c-Myc (mean ± SD) in DDP group were comparable to those in the control group. b Western blot analysis showed that Wnt1, β-catenin, CyclinD1 and c-Myc in the CKI group were significantly lower than those observed in the control group. The protein level of Wnt1, β-catenin, CyclinD1, and c-Myc in DDP group were comparable to those in the control group. The experiment was run in triplicate.
