Web9 de abr. de 2024 · Secreted predominantly by hepatocytes, hepcidin synthesis is regulated by two major mechanisms: iron status and inflammatory stimuli. High circulating iron stimulates hepcidin expression, which induces cellular retention of iron, decreases intestinal absorption of iron and lowers concentrations of circulating free iron [6,7]. WebAs clarified in our study, hepcidin expression was correlated with pStage and vascular invasion in patients with pancreatic cancer, and high expression in the hepcidin group indicated shorter OS. pN, adjuvant chemotherapy, and hepcidin expression were found to be independent prognostic factors for OS. intex power banks price
