#2739 Epigenetic Landscape of Pancreatic Neuro-Endocrine Tumors Reveals Distinct Cells of Origin and Means of Tumor Progression
Introduction: Pancreatic Neuroendocrine Tumors (PanNETs) arise from cells of the Islets of Langerhans. The majority of PanNETs are non-functional and their cell of origin cannot be defined analysing specific hormone production. Cell of origin assessment has proven importance to identify risk factors, prevent tumour development, and tailor treatment in many malignancies. Recent data on super-enhancer signatures has suggested a potential origin of PanNET from α- or β-cells. We and others have shown that distinct epigenetic profiles assessed by DNA methylation (DNAme) characterize genomic and prognostic groups of PanNET.

#1528 Medullary Thyroid Carcinoma Cell Lines – An Update
Introduction: Medullary Thyroid Carcinoma (MTC) originates from calcitonin-producing neuroendocrine C-cells of the thyroid gland. Mutations in the RET-proto-oncogene are associated with both sporadic and familial MTC. As MTC are poorly responsive to chemo- and radiation- therapy, surgery is the only curative treatment at the moment. The cytogenetics of MTC have been sparsely investigated because the cells are very difficult to cultivate. In the last three decades our research group has established 10 continues cell lines derived from primary tumor and lymph node metastasis of patients with either sporadic or hereditary MTC.

#113 Prolonged cell survival in xenografts from human digestive endocrine tumors
Introduction: Gastroenteropancreatic endocrine tumors have the capacity to achieve very large tumor masses despite usually very low proliferative rates. This suggests that neoplastic endocrine cells may have long life spans, implying the development of specific mechanisms able to promote cell survival.

#3076 Endometrial Small Cell Neuroendocrine Carcinoma: Case Report and Literature Review
Introduction: Endometrial small-cell neuroendocrine carcinoma (ESCNEC) is extremely rare. It is characterized by early regional and systemic spread leading to rapid development of lymph nodes, pelvic and extrapelvic metastasis and compromising the outcome.

#612 Serotonin in Blood: Assessment of its Origin by Concomitant Determination of β-Thromboglobulin (platelets) and Chromogranin A (enterochromaffin cells)
Introduction: Serotonin is produced in enterochromaffin (EC) cells, taken up and stored in platelets and released during platelet activation. Measurement of platelet-poor plasma serotonin is difficult, mainly due to platelet activation during blood sampling.

#2196 The Neuroendocrine Phenotype, Genomic Profile, and Therapeutic Sensitivity of GEPNET Cell Lines
Introduction: Patient tumour-derived cell lines have been widely used for studying the molecular mechanisms of tumours and their response to therapy. The establishment of cell lines from gastro-entero-pancreatic neuroendocrine tumours (GEPNETs) has proved difficult, but despite the challenges a limited amount of cell lines now exists.

#2270 Development of Pre-Clinical NEN Models – Limitations and Opportunities
Introduction: Pre-clinical research in neuroendocrine neoplasia (NEN) has long been impaired by the paucity of NET and NEC cell lines. Furthermore, established models have not been widely available or displayed unusual features (eg. p53 and ras mutations, high proliferation rate).

#933 The Cytotoxic Effect of Sunitinib on Human Bronchial Carcinoid Cell Lines and Primary Cultures is Counteracted by EGF and IGF-1, but not by VEGF
Introduction: Bronchial carcinoids (BC) are rare tumors originating from endocrine cells dispersed in the respiratory epithelium. The main BC treatment is surgery, but which is not feasible for large, infiltrating and metastatic disease. In these settings, medical therapy is often tried. Therefore it is important to identify new therapeutic targets and new molecules capable of providing adequate medical treatment for patients with BC. Sunitinib is an oral, small-molecule, multi-targeted receptor tyrosine kinase inhibitor.
