CDH1 and breast carcinoma: Among all CDH family members, CDH1/2/3/4/7/9/10/11/12/13/15/16/26 were significantly positively associated with a lower DMFS (Figure 4), and CDH1/2/4/6/7/11/12/13/15/22/23/24 mRNA expression levels were higher in breast cancer than in normal tissues in the Oncomine database (Figure 2A, 2B).
