#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.

#1560 Cannabinoids as Inhibitor of Tumour Growth and Invasiveness in Small Intestine Neuroendocrine Cancer
Introduction: Tumour cell invasion and proliferation is a key factor for the prognosis and progression of cancer. A recent study revealed that cannabinoids can inhibit tumour invasion and proliferation in breast cancer through the down-regulation of ID-1, an inhibitor of helix-turn-helix transcription factors.

#1115 Cancer Stem Cells in Small Intestine Neuroendocrine Cell Line P-STS: Isolation and Molecular Characterisation
Introduction: Cancer stem cells (CSCs) represent a small subpopulation of tumour cells responsible for invasive tumour growth. Even though the presence of CSCs in neuroendocrine tumours is documented, their role in neuroendocrine tumourigenesis and metastasis is not defined as yet.

#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.

#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).

#1040 TIM16 Inhibition Decreases Calcitonin Secretion and Enhances Sensitivity to Paclitaxel in a Human Medullary Thyroid Carcinoma Cells
Introduction: TIM 16 protein is part of the traslocase complex TIM 23 situated in the mitochondrial inner membrane, encoded by the Magmas gene, that is overexpressed in several tumors. Magmas silencing causes a greater sensitivity to apoptotic stimuli. We recently demonstrated that, in a human medullary thyroid carcinoma cell line (TT), compound 5, a TIM 16 inhibitor, was not cytotoxic but enhanced the proapoptotic effects of staurosporine

#2682 PAK4-NAMPT Dual Inhibition as a Novel Strategy for Therapy Resistant Pancreatic Neuroendocrine Tumors
Introduction: Pancreatic neuroendocrine tumors (PNET) remain an unmet clinical need. In this study, we show that targeting both nicotinamide phosphoribosyltransferase (NAMPT) and p21-activated kinase 4 (PAK4) could become a synthetic lethal strategy for PNET.

#2934 Vasostatin-1 Predicts Recurrence in Patients Submitted to Surgery for Nonfunctioning Pancreatic Neuroendocrine Tumors (NF-PanNET)
Introduction: An association between preoperative Vasostatin-1 (VS-1) plasma level and pathological features of aggressiveness was previously reported in patients with surgically resected nonfunctioning (NF) PanNET.

#2988 Epigenetic Treatment with Histone Deacetylase Inhibitor Enhances Uptake of [111In]In-DOTA-TATE by Increased SST2 Expression on Neuroendocrine Tumor Cells
Introduction: The somatostatin-2 receptor (SST2) is a target for peptide receptor radionuclide therapy (PRRT) in neuroendocrine tumors (NETs). By using epigenetic drugs, which can regulate gene transcription, PRRT efficacy may be further improved due to enhanced SST2 expression.

#3320 TGF-β increase caspase activation and migration in typical bronchial carcinoids
Introduction: Typical bronchial carcinoids (TBC) are well-differentiated neuroendocrine neoplasms (NEN) whose management can still be very challenging due to reduced sensitivity to therapy. Previous studies have reported TGF-β’s ability to activate mTOR pathway and induce epithelial to mesenchymal transition (EMT). Moreover, preliminary results show an overexpression of TGF-β signalling and caspase activation in TBC.
