In another study [36], HNF1B was also found deregulated in a mouse model of intraductal papillary mucinous neoplasm (IPMN) to PDAC progression with another duct-specific factor, SOX9, while the latter was not found deregulated in our data and was not predicted in our regulatory analysis. The gene discussed is HNF1B; the disease is pancreatic intraductal papillary-mucinous neoplasm.
