#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.

#387 Combined Blockade of Several Signalling Pathways Shows Marked Anti-Tumor Potential in Two Novel Mouse Phaeochromocytoma Cell Lines
Introduction: The current study explores novel targeted therapies for malignant pheochromocytomas (PCCs) and paragangliomas, utilizing a more benign (MPC) and a more malignant (MTT) PCC cell line. We have previously shown that the dual PI3K/mTORC1 inhibitor NVP-BEZ235 significantly reduced MPC and MTT cell viability, but increased ERK signalling.

#2101 The Effect of Temozolomide on Pancreatic Neuroendocrine Tumors in Vitro and Role of MGMT and MMR System in Temozolomide Resistance
Introduction: Temozolomide (TMZ) has been suggested as a treatment option for patients with pancreatic neuroendocrine tumours (PNETs). The tumour response to TMZ has been linked to expression levels of O6-methylguanine-DNA methyltransferase (MGMT) and components of the mismatch repair (MMR) system.

#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.

#624 Identification of New GPCR Targets in NET Cell Lines Using Ligand Screening
Introduction: Although somatostatin analogs constitute an important part of current therapeutic strategies, both hypersecretion and proliferation of NETs cannot be controlled efficiently in many patients. Identifying and dissecting new molecular targets and regulatory pathways may help to improve diagnostic and therapeutic options for NET patients.

#2008 Preliminary Evaluation of Influence of Different Targeted Drugs of Vascular Endothelial Growth Factor Signaling Pathway on the Proliferation of Neuroendocrine Neoplasm Cell Lines
Introduction: Sunitinib and bevacizumab are intracellular and extracellular inhibitor of vascular endothelial growth factor(VEGF) pathway respectively, the influence of both of which on the proliferation of neuroendocrine neoplasm (NEN) cell lines in vitro was not known yet.

#1183 Establishment of a New Human Pancreatic Neuroendocrine Tumour Cell Line
Introduction: The development of new therapeutic strategies for patients with pancreatic neuroendocrine tumours is impaired by the paucity of suitable pre-clinical models. Although the two available tumour cell lines BON and QGP have a neuroendocrine phenotype, the proliferation rate is too high for a well differentiated neuroendocrine tumour.

#1542 Selective Inhibition of PI3Kalpha (BYL719) - Promising Therapeutic Option for Neuroendocrine Tumors?
Introduction: Neuroendocrine tumors are heterogeneous, often functional malignancies and their therapeutic options are limited. As the PI3 kinase signaling is ­in GEP-NENs, selective PI3Kalpha inhibitors may be more potent than panPI3K inhibitors.

#1999 Study of Cell Cycle Protein Expression Pattern in Bronchial Carcinoids: A New Potential Target for Medical Therapy?
Introduction: Bronchial Carcinoids (BCs) are rare neuroendocrine neoplasms arising from respiratory epithelium. The only effective treatment option is surgery, but its efficacy is frequently limited by metastatic spread. Everolimus prolongs progression free survival but patients may develop resistance. Previous studies demonstrated that Everolimus reduces viability of NCI-H720 cells (Atypical Carcinoid) but not of NCI-H727 cells (Typical Carcinoid). Everolimus decreases Ciclyn D1 protein levels in both cell lines but NCI-H727 cells survive, indicating a derangement in cell cycle control.

#874 The pan-TRK Inhibitor GNF5837 Inhibits Cell Viability and Akt and MAPK Signaling in Human Neuroendocrine GOT1 Tumor Cells
Introduction: The tropomyosin receptor kinase family (TRKA, TRKB, TRKC) effects tumor cell growth in various models. Recent preclinical studies in neuroendocrine carcinoma of the lung cell lines have shown that Trk receptors might be a therapeutic target for neuroendocrine neoplasias.
