An activated wild-type p53 gene expression signature plus luminal biomarkers |
Choi et al. (2014) |
High EGFR (and its ligands) expression |
High FGF3 expression |
|
Expression of “mesenchymal” markers (TWIST1/2, SNAI2, ZEB2, VIM)
|
Expression of “epithelial” markers (E-cadherin/CDH1, members of the miR-200 family)
|
|
p63 activation |
Features of active PPARgamma and estrogen receptor transcription |
Consistently resistant to neoadjuvant MVAC chemotherapy |
Squamous differentiation, sarcomatoid features |
Enriched with activating FGFR3 mutations |
|
More aggressive metastatic disease at presentation |
Potentially FGFR inhibitor sensitivity |
|
Shorter overall survival, shorter disease specific survival |
