#2738 Patient-Derived Organoid Models of Human Neuroendocrine Carcinoma
Introduction: Gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC) is a poorly understood disease with limited treatment options. Due to its low incidence and wide tissue distribution few representative preclinical models are available

#2898 Novel Preclinical Models of Small Bowel Neuroendocrine Tumors for Drug Screening
Introduction: The incidence of neuroendocrine tumors (NETs) from the small bowel (SBNETs) has increased markedly over the past several decades. Many patients with these tumors present with metastatic disease, and research into new treatment options for these tumors have been hindered by the limited number of patient-derived SBNET cell lines and in vivo models available for drug testing.

#2692 Development of Ex-Vivo Models of Metastatic Neuroendocrine Neoplasms
Introduction: The lack of relevant in-vivo and in-vitro models has precluded investigations of the pathophysiology of metastatic NENs. Organotypic tumour slices retain the complexity of tumours in-vivo without extensive manipulation of the tissue.

#2980 Metabolic Dysregulation and Circadian Clock in Cellular Models of Neuroendocrine Tumors
Introduction: The circadian clock genes encode transcription factors whose interaction with nuclear receptors allows the regulation of cellular metabolism.The invalidation of the genes of the clock core is associated with the development of many endocrine diseases including neuroendocrine cancer. Recently, the family of transcriptional coactivators PGC-1a has been identified as a key element in the integration of cellular metabolic state with the circadian clock. PRC, as a member of the PGC-1 family, was able to interact with several transcription factors, including the CLOCK factor. The specific induction of this PRC factor by the cell cycle, to modulate the energy function, the MAPkinase pathway and the expression of microRNAs, makes it a key factor in the metabolic adaptation of cancer cells.

#2974 MEK/RAF and PARP as Novel Targets in Neuroendocrine Neoplasms – First Results from a Molecular in vitro Tumor Board
Introduction: Neuroendocrine neoplasms (NEN) are a heterogeneous group comprising well differentiated neuroendocrine tumors (NET) and poorly differentiated neuroendocrine carcinomas (NEC). Although, major progress has been made in the development of targeted therapies in various cancers, establishment of a promising personalized therapy in NEN is still pending. So far, a lack of suitable preclinical models represent a major challenge concerning the validation of a mutational based targeted therapy (MBTT)

#406 YF476, a Gastrin Receptor Antagonist, Causes Regression of Tumors and Normalizes Serum Chromogranin A in Patients with Type 1 Gastric Carcinoids
Introduction: Chronic atrophic gastritis (CAG) results in achlorhydria, hypergastrinemia and, in some patients, gastric carcinoids (type 1 GCs). Type 1 GCs may become malignant and metastasize. Current treatments of type 1 GCs, such as polypectomy, somatostatin analogues and antrectomy, have their disadvantages. YF476 – a potent, selective, orally active and well-tolerated gastrin receptor antagonist in pre-clinical studies – prevented, as well as reduced, the number and size of gastric carcinoids and carcinomas in rodent models.

#1166 mTOR Pathway Inhibition Sensitizes Insulinoma Cells to Streptozotocin Induced Apoptosis
Introduction: Pancreatic neuroendocrine tumors (pNETs) are generally chemoresistants probably due to low proliferation rate and defects in apoptotic pathway. Targeted therapies are new encouraging options for pNETs however; clinical trials show limited objective response. Combination of chemotherapy and targeted therapy could be a new solution in therapeutic care. Streptozotocin (STZ) is the 1st line of therapy for unresectable pNETs.

#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.

#1867 Establishment of the First Well-Differentiated in Vivo Human Pancreatic Neuroendocrine Tumor Model
Introduction: The development of new therapeutic strategies for cancer patients relies on the in vitro and in vivo testing of novel substances in the pre-clinical setting. So far, this has not been possible for pancreatic neuroendocrine tumors (pNET) due to lack of suitable animal models resembling the disease course in human patients.

#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).
