Pancreatic cancer markers based on aberrant glycosylation of serum proteins

Cancer is one of the leading causes of death worldwide. Pancreatic ductal adenocarcinoma (PDAC) is characterized by high intrinsic aggressiveness and late diagnosis, causing poor prognosis and resulting in the lowest five-year survival rate among all cancers. Nowadays, there is no biomarker for PDAC...

Sumario:Cancer is one of the leading causes of death worldwide. Pancreatic ductal adenocarcinoma (PDAC) is characterized by high intrinsic aggressiveness and late diagnosis, causing poor prognosis and resulting in the lowest five-year survival rate among all cancers. Nowadays, there is no biomarker for PDAC diagnosis approved. The survival rate of cancer patients increases when they are diagnosed in the early stages of the pathology; and for this reason, the research of new biomarkers is of great interest. Tumour cells present aberrant glycosylation on their cell surface and also in the secreted glycoconjugates. Hence, a strategy for new tumour biomarker discovery is based on the identification of specific glycoforms. This work has explored the glycosylation of two serum glycoproteins, the alpha-1-acid glycoprotein (AGP) and the ceruloplasmin (CP). The glycosylation of the epithelial mucins MUC1 and MUC5AC in healthy and PDAC tissues has also been analysed.
