Fig. 5 Wnt signaling induces CRBN-mediated degradation of a subset of endogenous substrates.

a HEK cells were transfected with the indicated smart-pool siRNA, followed by PBS or Wnt3a treatment for 24 h. Extracts of these cells were evaluated by immunoblotting. A representative immunoblot (n = 3 independent experiments) is shown. b–d HEK cells were co-treated with cycloheximide along with PBS or Wnt3a. Extracts of these cells were evaluated by immunoblotting. CK1α levels from immunoblots were quantitated, normalized to HSP90 levels, and plotted to determine the turnover of the indicated protein in response to Wnt3a (mean ± SEM, n = 3 independent experiments). e–g HEK cells were transfected with control (CTRL) or one of two distinct CRBN siRNA and co-treated with Wnt3a and cycloheximide. Extracts of these cells were evaluated by immunoblotting. CK1α levels from immunoblots were quantitated, normalized to HSP90 levels, and plotted to determine the turnover of the indicated protein in response to Wnt3a (mean ± SEM, n = 3 independent experiments). Asterisks in b–g indicate statistical significance (two-way ANOVA analysis, ***p value < 0.001, ****p value < 0.0001). h Extracts of HEK cells treated for 24 h with different doses of Wnt3a or lenalidomide were evaluated by immunoblotting. A representative immunoblot (n = 3 independent experiments) is shown.
