This C/EBP delta binding site in aromatase promoters I.3/II seems to act as a positive regulatory element in non-p65-overexpressing breast cancer epithelial cells, whereas it is possibly inactive in p65 overexpressing cancer epithelial cells, such as estrogen receptor-negative breast cancer cells.
We also demonstrate how this methodology can be used to study molecular pathways involved in cancer by performing in-depth characterization of biological and pharmacological mechanisms such as p65 nuclear translocation via TNF stimuli, and to predict the treatment outcome in the clinic via MDT response to taxane-based therapies.
