PSMD11 and pancreatic ductal adenocarcinoma: In this study, the expression analysis of PSMD11 and PSMD14 across cancers revealed that they were differentially expressed in a variety of tumors, including pancreatic ductal adenocarcinoma, and analysis using the GEO database revealed that the expression levels of these two proteins were significantly higher in pancreatic ductal adenocarcinoma tissues than in normal pancreatic tissues.
