Cell monolayer scratching assay was performed to explore the role of quercetin in the migration ability of SMMC-7721 cells. Western Blot and immunofluorescence assay were conducted to detect the protein expression of transcriptional co-suppressor, CtBP1, and epithelial adhesion molecule, E-cadherin. The migration ability of SMMC-7721 cells was decreased by the addition of quercetin in a time and concentration dependent manner. Results of western blot and immunofluorescence assay demonstrated that quercetin inhibited the expression of CtBP1, while up-regulated the expression of E-cadherin. These findings suggest that quercetin contributed to the upregulation of E-cadherin through inhibition of CtBP1 expression. This in turn hinders the underlying EMT process, and finally prevents the invasiveness and metastasis of HCC cells. However, the mechanism how quercetin up-regulation CtBP1 in HCC cells still need to be elucidated. }
