Furthermore, when data were stratified for oestrogen (ER), progesteron (PR) receptor, Human Epidermal growth factor Receptor 2 (HER2) or triple negative subtypes, we confirmed a significant and positive correlation between high N-cadherin level and overall survival in patients with either ER- or PR-positive breast cancers (Figure 6b,d). The gene discussed is CDH2; the disease is breast cancer.
