Akamatsu et al. [11] have identified four specific miRNAs (miR-7, miR-34a, miR-181d, and miR-193b) that are associated with constitutive mitogen-activated protein kinase activation, commonly seen in pancreatic neoplastic diseases (PDAC and IPMN). Here, WNK2 is linked to pancreatic intraductal papillary-mucinous neoplasm.
