Consistent with basal B PDXs, the TIC/EMT high patient group was enriched for co-expression of FGFR1 and HGF. Importantly, we found that co-expression of HGF and FGFR1 predicts poor relapse-free survival specifically among basal breast cancers, providing further support that FGFR1 and MET pathways contribute to the tumourigenicity of highly mesenchymal breast cancers. The gene discussed is HGF; the disease is breast carcinoma.
