The function of HNF1A, however, is cell‐type specific (Servitja et al, 2009), and both co‐expression network analysis of PDAC samples and in vitro studies suggest that HNF1A has a tumor‐suppressive function in pancreatic exocrine cells (Hoskins et al, 2014; Luo et al, 2015). Here, HNF1A is linked to neoplasm.
