Additional file 2: of IΚΚε cooperates with either MEK or non-canonical NF-kB driving growth of triple-negative breast cancer cells in different contexts

Figure S1. Protein activity suppressed by inhibitors. Western blot quantification and short time point for phospho-ERK western blot. a) Quantification of western blot represented in Figure 2a showing protein level changes in BT549 or MDA MB 468 cells after 6 h treatment with indicated inhibitors. Quantification is relative to vehicle control lanes. b) Western blot showing decrease in phosphorylated ERK1/2 upon 30-min exposure to IKKε inhibitor, and accompanying graph for quantitation of phospho-ERK, as normalized to GAPDH, and relative to expression in untreated MDA468.
