摘要:AIM: To study the influence of CXCR4/stromal cell-derived factor-1 (SDF-1) axis on E-cadherin/beta-catenin complex expression in HT29 colon cancer cells and its underlying mechanisms.; METHODS: Effect of SDF-1 on E-cadherin/beta-catenin expression was detected by immunocytochemistry. E-cadherin and p-catenin mRNA expression levels were measured by reverse transcriptase-polymerase chain reaction. SDF-1-induced phosphorylation of phosphatidylinositol 3-kinase (PI3K)/AKT and p-catenin was detected by Western blotting.; RESULTS: The E-cadherin and beta-catenin mRNA expression levels in HT29 cells were lower 48 h after incubated with SDF-1 at the concentrations of 20 and 40 ng/mL (P < 0.05). SDF-1-induced significant phosphorylation of PI3K/AKT and p-catenin. AMD3100 and LY294002 inhibited the phosphorylation cif PI3K/AKT and beta-catenin.; CONCLUSION: SDF-1 down-regulates the E-cadherin/beta-catenin complex expression in HT29 cells by decreasing mRNA synthesis and increasing p-catenin phosphorylation.
