CDH1 and invasive breast carcinoma: The change in FOXA1 strongly coincided with a number of epithelial marker genes (GRHL2, CDH1, and EPCAM) as well as HER3. Additionally, expression of HER2, DDR1, and the TFs GATA3, XBP1, and PBX1 were also strongly correlated with FOXA1. To validate this observed correlation, we analyzed the genes correlated with FOXA1 using TCGA provisional RNAseq data from the Breast Invasive Carcinoma samples using cbioportal.org41,42.
