Western blot analysis of ERK5, ERK1/2, and RSK activation in TNBC cells. (A) MDA-MB-231, (B) BT-549, (C) TU-BcX-4IC, and (D) TAMR MCF-7 cells. Data represent the ± SEM of three different experiments for each inhibitor compared to DMSO control. *p<0.05; **p<0.01; ***p<0.001; ****p<0.0001 vs DMSO control group determined by one-way ANOVA with the Bonferroni post hoc test.
