Glycans and glycosylated proteins in serum can serve as biomarkers; it was previously reported that WFA-positive Mac-2-binding protein level was elevated in chronic pancreatitis, while the abundance of cancer-specific N-glycans on leukemia inhibitory factor receptor (i.e., centrosome-associated protein 350), vacuolar protein sorting-associated protein 13A, and haptoglobin was altered in pancreatic cancer subjects [31,32]. The gene discussed is LGALS3BP; the disease is familial pancreatic carcinoma.
