Fig. 1

Baseline expression level of CBP and GCN5 in a panel of normal and cancer breast cells. Upper panel: Immunoblot images for a CBP and b GCN5 expression in normal cells (HMEpC and HME1) and in breast cancer cells (MCF7, T47D, BT474, SkBr3, BT-549, MDA-MB-231, MDA-MB-468, BT-20 and Hs578T). Lower panel: Graphs for relative expression level of CBP and GCN5 after normalization to β-actin. Full blots images are available in Additional file 1: Figure S4. Average present as mean ± SEM (n = 3). *p < 0.05 versus HMEpC, unpaired t test. c, d Correlation between the expression level of CBP and c the expression of HER2 or d ERα in nine breast cancer cell lines. Shown are “r” values (Pearson’s correlation coefficient) with the corresponding p values
