The transmembrane mucin 1 (MUC1) onco-protein is aberrant overexpressed in breast cancer cells and associates with HER2.
It has been demonstrated that silencing MUC1-C in HER2-overexpressing breast cancer cells results in downregulation of constitutive HER2 activation. But what is the effect of MUC1 downregulation in HER2 gene expression in trastuzumab-responsive breast cancer cells.
Which other genes (in addition to HER2) can we analyze by RT-PCR to identify the effect of MUC1 inhibition in HER2 gene expression?
