Figure Legend Snippet: (A) Henryin does not affect the amount of total β-catenin and pho-β-catenin in SW480 cells. (B) Henryin does not affect the distribution of β-catenin in cytosol and nucleus fractions in SW480 cells. SW480 cells were treated with the indicated dosages of henryin for 24h. The cell extracts or fractions were prepared and analyzed by western blotting. Lamin A/C and β-actin were used as loading controls of nuclei and cytoplasm proteins, respectively. (C) Henryin antagonizes the Wnt signaling stimulated with LiCl or β-catenin. HEK293T cells were transiently transfected with ST-Luc and β-catenin or constitutively active β-catenin (S37A) plasmids, respectively, or treated with LiCl (20mM). Around 3h after transfection or treatment, henryin was added and cells were incubated for an additional 24h. Each bar is the mean ± SD from three independent experiments. (D) Henryin, but not enmenol and minheryin C, reduced the TCF4 levels associated with β-catenin in SW480 cells in a dose dependent manner. Cells were treated with the indicated dosages of henryin and its analogs enmenol and minheryin C for 12h and immune-precipitation was performed by β-catenin antibody with mouse IgG as a control, and then TCF4 was detected by western blotting. (E) Henryin directly disrupts the interaction of β-catenin with TCF4 in the in vitro binding assay. Human recombinant β-catenin (0.8µg) and TCF4 (0.5µg) were mixed, incubated with different concentrations of henryin and its analogs enmenol and minheryin C, and the mixture was subjected to co-immunoprecipitation with β-catenin antibody and western blotting analysis with TCF4 antibody, with mouse IgG used as control. (F) Quantification of the western blots shown in D and E. The software ImageJ was used to analyze the intensities of bands. Data was presented as mean ± SD from three experiments. Hen, henryin, En, enmenol, Min, minheryin C.
