We analyzed circulating galectin-9 in healthy individuals (n = 28), patients with chronic pancreatitis (n = 18), intraductal papillary mucinous neoplasms (IPMN, n = 18), and PDAC (n = 70, Supplementary Table S3). The gene discussed is LGALS9; the disease is pancreatic intraductal papillary-mucinous neoplasm.
