#2180 BRAF-V600E Driven Mutations in Grade 3 Neuroendocrine Carcinomas of Colon Origin: Results from Genomic/Epigenomic Profilings and Patient-Derived Mouse Model
Introduction: NECs of colon origin are orphan and highly aggressive neoplasms with limited molecular knowledge.

#1107 The Chicken Chorioallantoic Membrane Assay as a Preclinical Model for the Research of Rare Gastrointenstinal Neuroendocrine Tumours
Introduction: Preclinical trials of cancer therapeutics require both in vitro and in vivo evaluations. For neuroendocrine tumours (NET) studies are limited to cell lines, thus xenograft models are needed for screening and evaluation of anti-cancer drugs. The chick chorioallantoic membrane (CAM) assay is a well-established model system to investigate tumour growth, angiogenesis and metastasis.

#1180 A Novel Human Cell Line from Familial Medullary Thyroid Carcinoma
Introduction: Cell lines from hereditary medullary thyroid carcinomas (MTC) are very rare, therefore, there is a substantial need to establish new cell lines. Here, we present a novel familial MTC (FMTC) cell line, designated SCHWE.

#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.

#1637 The Effect of the Autophagy Inhibitor Chloroquine (CQ), Alone or in Combination with mTOR Inhibitors, on Neuroendocrine Tumor (NET) Growth and Metastatic Spread in Mouse Models
Introduction: mTOR inhibitors (mTORi) such as RAD001 demonstrated promising anti-cancer effect in NETs. Autophagy, a cell survival mechanism, is activated by mTORi. We have recently shown in the human NET cell line BON1 that autophagy is essential for cell survival. Treatment with CQ alone or together with mTORi robustly inhibited cell proliferation and survival, suggesting that treatment with CQ may potentiate the anti-tumorigenic effects of mTORi.

#2280 The BON-SSTR2 Chicken Chorioallantoic Membrane (CAM) Model for the Analysis of Lu-17-DOTATOC Sensitizing Agents
Introduction: Peptide radioreceptor therapy (PRRT) is a promising therapy option for SSTR2-positive pancreatic neuroendocrine neoplasms (NEN). However, therapeutic effects are often not satisfying concerning sensitivity to PRRT. We hypothesize that the slow proliferation of NENs provides sufficient time for the repair of beta-particle induced-DNA damage. The ubiquitin-proteasome-system is involved in DNA damage repair and affected by the proteasome inhibitor bortezomib (Velcade®). The inhibition of DNA damage repair during PRRT may be an option to improve therapy response in NEN. We have recently demonstrated the damage repair inhibitory and pro-apoptotic effect of bortezomib in NEN in vitro (Briest et al., in revision).

#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.

#204 A Proteomic Approach Identifies Novel Proteins Involved in Invasion Mechanisms in Enteroendocrine Carcinomas
Introduction: Enteroendocrine tumors dramatically lack reliable biomarkers to accurately select therapeutic strategy, due to a poor knowledge of molecular mechanisms leading to local invasion and dissemination.
