N-cadherin expression was high in 127 of the 177 CCA tissue samples (71.8%; Table 3, Figure 4A, C1, C2), and the KIAA1199 and N-cadherin expression levels were significantly positively correlated in CCA specimens according to Spearman’s rank correlation analysis (r=0.311, P<0.001; Table 3). The gene discussed is CDH2; the disease is cholangiocarcinoma.
