Fig. 4From: The impact of CBP expression in estrogen receptor-positive breast cancerEffect of CBP downregulation by siRNA on the expression of ERĪ± in MCF7 and T47D cells. a, b Western blot analysis of CBP and ERĪ± proteins in a MCF7 and b T47D cells transfected with negative control (NC) or CBP siRNA for 24ā96Ā h. The graphs show the relative amounts of ERĪ± protein normalized to Ī²-actin. Fold change of ERĪ± expression was done over cells transfected with NC siRNA for each time point. Full blots images are available in Additional file 1: Fig. S10. Average present as meanāĀ±āSEM (nā=ā3). *pā<ā0.05 versus untreated control, unpaired t testBack to article page
