In addition to proteins known to be secreted, we identified several putatively intracellular, non-N-glycosylated proteins, such as β-glucocerebrosidase and paladin, linked to pancreatic cancer (PC) as well as proteins associated with extracellular vesicles (EVs) in PC, such as dCTP pyrophosphatase 1. Here, PALD1 is linked to familial pancreatic carcinoma.
