Inhibited nuclear translocation of β-catenin and Smad 2/3 by sLRP6E1E2-expressing Ad. Upon Wnt3a (100 ng/mL) stimulation, the expression of β-catenin and Smad 2/3 was reduced at the cytosols, but increased in the nucleus. In contrast, transduction with dEl-k35/sLRP6E1E2 (50 MOI) decreased nuclear translocation of (a) β-catenin and (b) Smad 2/3. The data are representatives of three independent experiments.
