CDH2 and familial pancreatic carcinoma: Although, the expression of N-cadherin or Vimentin was not detected in HPAC cells, which rarely express mesenchymal markers, downregulation of vimentin and upregulation of E-cadherin by GLRX3 knockdown was detected in the other pancreatic cancer cell line, CFPAC-1 (Additional file 1: Fig. S4).
