Supplementary Figure 3: α-catenin does not regulate IκBα, RelA and RelB protein levels in luminal-like mammary cells.

(a) Immunoblotting of α-catenin, IκBα, RelA, RelB and HSP90 in T47D and MCF10A cells transduced with two independent α-catenin shRNAs. (b, c) Immunoblotting of α-catenin, IκBα, p-RelA, RelA and HSP90 in α-catenin shRNA-transduced T47D (b) and MCF10A (c) cells, with or without TNFα treatment (20 ng/ml). Uncropped images of blots are shown in Supplementary Figure 7.
