To examine differences in DNA methylation of MUC1, MUC2 and MUC4 among pancreatic neoplastic lesions, we evaluated pancreatic juice samples from 15 patients with PDAC, 11 patients with gastric-type IPMN, 8 with intestinal-type IPMN, 9 with other IPMN types, and 2 non-neoplastic pancreases (Table 1). The gene discussed is MUC4; the disease is pancreatic intraductal papillary-mucinous neoplasm.
