Another study found that quercetin inhibits the migration ability of HCC cells by inhibiting the expression of transcriptional co-suppressor, C-terminal binding protein 1 (CtBP1), and up-regulating the expression of epithelial adhesion molecule E-cadherin, a tumor suppressor protein (Tang et al., 2018). This evidence concerns the gene CTBP1 and hepatocellular carcinoma.
