This antibody also detected a 20 kDa protein corresponding to the predicted molecular weight of native AGR2 in the cell lysate of CFPAC-1, which expresses a high level of AGR2, but not in the pancreatic cancer cell line MiaPaca, which expresses a low level of AGR2 (Figure 2), nor in the normal pancreatic ductal cell line HPDE (data not shown). The gene discussed is AGR2; the disease is familial pancreatic carcinoma.
