Figure 2. CSNK1E is an essential gene in breast cancer cells with active β-catenin.
(A) Schematic overview of RNAi screens and integrative analysis to identify essential regulators of β-catenin activity and cancer cell proliferation. (B) Immunoblot analysis of CK1ε levels after RNAi-induced suppression. (C) Effects of CSNK1E suppression with two shRNA sequences (A and B) on proliferation. Graph shows mean ± SD of a representative experiment performed in triplicate.
