#4299 Defective DNA repair promotes progression of small intestinal neuroendocrine tumours despite a lack of common genomic drivers

#3959 Sortilin: A novel marker and potential therapeutic target for functional neuroendocrine tumors

Introduction: A subset of neuroendocrine tumors (NETs) causes a hormone-related disease (functional syndrome); e.g. carcinoid syndrome due to over-secretion of mainly serotonin. Notably, on a molecular level, what distinguishes this subset of functional NETs from nonfunctional tumors is unknown. Furthermore, accurate models of functional NETs are missing. Sortilin, a widely expressed transmembrane receptor, is expressed in many cancer cells, including NETs, and is involved in secretion processes.
