GSK3B and hepatocellular carcinoma: Daucosterol in hepatocellular carcinoma lines HepG2 and SMMC-7721 reduced the levels of β-catenin and Wnt5a while increasing the expression of GSK3β, causing a drop in the proliferation, migration, and invasion capacity of the cells—the effects that were specifically countered by Wnt activation with the GSK3β inhibitor SB-216763 [69].
